1 00:00:07,980 --> 00:00:11,600 Hey hey hey everybody this is Caleb with Dev's Loeb's dot com. 2 00:00:11,610 --> 00:00:17,100 And in this awesome video we're going to request location services and I'm going to show you what is 3 00:00:17,100 --> 00:00:20,760 new in Iowa 11 forgetting the user's location. 4 00:00:20,760 --> 00:00:22,280 There are some things that have changed. 5 00:00:22,380 --> 00:00:26,340 Some things you need to know about that are really important to ensure that your app gets approved on 6 00:00:26,340 --> 00:00:27,380 the App Store. 7 00:00:27,540 --> 00:00:31,440 If you're using these skills for an app that you're going to release this one as well we're going to 8 00:00:31,440 --> 00:00:35,670 teach you best practices to make sure that you know what is new and what is up. 9 00:00:35,670 --> 00:00:42,320 So open your X called Project and let's get started requesting location services. 10 00:00:42,570 --> 00:00:45,920 So to do this we're going to need to go into map B.c. 11 00:00:46,440 --> 00:00:51,830 And of course to get location we're going to need to import the Core Location frameworks so go ahead 12 00:00:51,830 --> 00:00:56,800 and type import Core Location and that looks great. 13 00:00:56,940 --> 00:01:02,900 And now what we need to do is we need to create an instance of a C-L location manager. 14 00:01:03,020 --> 00:01:08,460 OK that's what we're going to use to manage locations of course see a location manager makes sense that 15 00:01:08,460 --> 00:01:10,020 it manages locations. 16 00:01:10,020 --> 00:01:18,180 So above view did load go Hedden type var location manager whoops capital M and we're going to set it 17 00:01:18,180 --> 00:01:23,720 to be equal to see location manager and we're going to instantiate it from the get go. 18 00:01:23,910 --> 00:01:24,780 All right. 19 00:01:24,900 --> 00:01:30,050 Now similarly to our map view we need to also set the delegate of our location manager. 20 00:01:30,150 --> 00:01:35,800 So go ahead and type location manager dot delegate equals self OK. 21 00:01:35,820 --> 00:01:42,250 And if you build and run this you'll notice it says cannot assign value of map b c to see location manager 22 00:01:42,250 --> 00:01:43,350 or delegate. 23 00:01:43,350 --> 00:01:48,540 The reason for that is because we have not conformed to it like we have MKM that you delegate. 24 00:01:48,540 --> 00:01:54,350 So go ahead and do that by creating another extension called extension Matthysse. 25 00:01:54,690 --> 00:02:01,550 And it's going to conform to C-L location manager delegate and give it some curly braces. 26 00:02:02,190 --> 00:02:05,890 So as soon as you do that you'll notice that the error goes away. 27 00:02:05,910 --> 00:02:12,610 This also means that there are no required methods to conform to cel location manager delegate. 28 00:02:12,660 --> 00:02:19,590 Unlike you I table view or collection view there are some required methods that you conform to but there 29 00:02:19,590 --> 00:02:21,830 are none foresee allocation managers delegate. 30 00:02:21,850 --> 00:02:24,900 We're going to add some though so that we can actually have an app that works because you know that's 31 00:02:25,200 --> 00:02:26,830 important or whatever. 32 00:02:26,870 --> 00:02:28,640 Now it's totally important anyway. 33 00:02:28,650 --> 00:02:35,010 So in our extension we're going to use one of the given functions but we're also going to create one 34 00:02:35,010 --> 00:02:36,100 of our own. 35 00:02:36,150 --> 00:02:42,600 So we're going to go ahead and we're going to basically write a function of our own first called configure 36 00:02:43,620 --> 00:02:46,800 location services. 37 00:02:47,190 --> 00:02:54,470 And inside this function might give us some space here so we can see stuff awesome inside this function 38 00:02:54,480 --> 00:03:01,350 we're basically going to check to see is our app authorized to grab our location. 39 00:03:01,680 --> 00:03:05,510 If not it's going to go ahead and request those services. 40 00:03:05,640 --> 00:03:07,580 If it is it's just going to return. 41 00:03:07,700 --> 00:03:11,640 OK so it's a way to check to see if we are authorized to use our location. 42 00:03:12,420 --> 00:03:17,100 But you know what we need to actually create a variable that's going to keep track of our authorization 43 00:03:17,100 --> 00:03:17,820 status. 44 00:03:17,820 --> 00:03:18,630 So to do that. 45 00:03:18,630 --> 00:03:19,710 Go ahead. 46 00:03:20,190 --> 00:03:21,520 It's actually going to be a constant. 47 00:03:21,570 --> 00:03:34,050 So go ahead untyped let off rise zation status equals a location manager dot wups authorization. 48 00:03:34,560 --> 00:03:35,090 Okay. 49 00:03:35,310 --> 00:03:38,750 Sorry I can't type C-L location manager. 50 00:03:38,850 --> 00:03:42,000 Authorization status if you option click on that you'll see. 51 00:03:42,000 --> 00:03:48,070 This is a function from the location manager that returns C-L location authorization status. 52 00:03:48,070 --> 00:03:54,450 Okay and if you pull that up in the help docs you'll notice that it is of type in 32 the number but 53 00:03:54,450 --> 00:03:59,740 basically these are constants that indicate whether the app is authorized to use location services. 54 00:03:59,850 --> 00:04:00,570 OK. 55 00:04:00,900 --> 00:04:07,200 So authorization status is there and it's going to be checking to see if we're authorized or not. 56 00:04:07,200 --> 00:04:15,080 So what we're going to do is we're first going to check to see if our authorization status is not determined. 57 00:04:15,090 --> 00:04:17,600 That's the name of one of the authorization statuses. 58 00:04:17,610 --> 00:04:22,320 So go ahead and type if authorization status is not determined. 59 00:04:22,350 --> 00:04:25,840 Meaning if the app doesn't know if it's approved or denied. 60 00:04:26,130 --> 00:04:30,450 We're going to go ahead and we're going to call location manager. 61 00:04:30,520 --> 00:04:33,770 That request always authorization. 62 00:04:33,770 --> 00:04:39,540 This is going to request authorization so that our location is used always whether the app is open or 63 00:04:39,540 --> 00:04:40,190 not. 64 00:04:40,510 --> 00:04:48,900 OK then we're going to say else meaning if it is determined maybe it's denied maybe it's approved for 65 00:04:48,990 --> 00:04:54,210 when in use authorization we're going to go ahead and just return right because if we already are approved 66 00:04:54,210 --> 00:04:57,000 or already are denied there's no need to do anything else. 67 00:04:57,000 --> 00:04:58,310 We can just return. 68 00:04:58,350 --> 00:05:02,040 So that's how we're going to configure location services. 69 00:05:02,040 --> 00:05:02,910 All right. 70 00:05:03,000 --> 00:05:04,340 Very very cool. 71 00:05:04,380 --> 00:05:09,210 And now what we need to do is we need to call this function to run as soon as the view loads. 72 00:05:09,220 --> 00:05:12,030 So it's going to check to see if if we're good to go. 73 00:05:12,100 --> 00:05:15,540 So call it from view did load configure location services. 74 00:05:15,550 --> 00:05:18,850 And let's go ahead and build and run it to see if it works. 75 00:05:20,490 --> 00:05:21,930 Very cool. 76 00:05:21,930 --> 00:05:23,130 Where did we go. 77 00:05:23,130 --> 00:05:23,910 There it is. 78 00:05:24,360 --> 00:05:24,970 OK. 79 00:05:26,600 --> 00:05:30,080 And it looks like it's not working but check out the terminal here. 80 00:05:30,080 --> 00:05:36,370 It says the apps info up the list must contain both and s location always. 81 00:05:36,410 --> 00:05:44,360 And when in use usage description and as location when in use usage description keys with string values 82 00:05:44,360 --> 00:05:49,630 explaining to the user how the app uses this data Apple is huge on privacy. 83 00:05:49,630 --> 00:05:53,960 So we've got to make sure we explain to the user exactly how we're using their data. 84 00:05:53,960 --> 00:05:59,190 So to do this go ahead and go to info's up the list and down at the bottom if you hover over the bottom 85 00:05:59,190 --> 00:06:05,930 and you see the plus and minus that pop up click on the plus and type privacy and then scroll down to 86 00:06:05,930 --> 00:06:07,550 find location. 87 00:06:08,030 --> 00:06:12,880 And we're going to go ahead and we need to use location always usage description which I'll pull this 88 00:06:12,890 --> 00:06:19,430 open so you can see that location always usage description and do another one here click. 89 00:06:19,430 --> 00:06:22,230 Plus privacy location. 90 00:06:22,340 --> 00:06:28,910 When in use usage description and then furthermore we need another one and I actually copy it from here 91 00:06:29,440 --> 00:06:34,240 and that's location always and when in use the usage description that's a mouthful. 92 00:06:34,370 --> 00:06:39,270 I'm going to copy that and paste that in here because in X code beta it's not yet working. 93 00:06:39,270 --> 00:06:42,000 So you actually need to paste in this long name. 94 00:06:42,080 --> 00:06:44,140 It doesn't look nice and pretty like this. 95 00:06:44,150 --> 00:06:49,280 Now the thing is for all three of these we can use the same description but we need to use all three 96 00:06:49,280 --> 00:06:57,020 of them because in iOS 11 Apple has changed location services work instead of only showing when in use 97 00:06:57,110 --> 00:07:07,550 or always use or do not allow it forever it's basically been you can show one or the other or at different 98 00:07:07,550 --> 00:07:08,220 times. 99 00:07:08,270 --> 00:07:09,340 It's been a mess. 100 00:07:09,500 --> 00:07:13,130 But Apple is basically wanting their apps to be more user centric. 101 00:07:13,130 --> 00:07:15,950 The user is completely in control of how their data is used. 102 00:07:15,950 --> 00:07:16,920 Like it says. 103 00:07:17,120 --> 00:07:21,930 So when this pops up it's going to give the user three options when in use. 104 00:07:21,950 --> 00:07:27,860 Always in use or disallow instead of one or the other at different times based on the context so we're 105 00:07:27,860 --> 00:07:31,530 going to give the user the choice to decide which is kind of cool. 106 00:07:31,760 --> 00:07:43,850 So in order to do this we're going to say this app requires your location to pull photos from flicker 107 00:07:43,910 --> 00:07:45,370 which we are using. 108 00:07:45,480 --> 00:07:50,240 We should put a period at the end because that's a sentence we are going to use that so go ahead and 109 00:07:50,240 --> 00:07:51,140 copy this. 110 00:07:51,140 --> 00:07:56,340 Paste it here and then paste it here for all three of these keys and values. 111 00:07:56,350 --> 00:07:58,160 OK we're going to just save it like that. 112 00:07:58,160 --> 00:08:03,450 And now that that's done we should be able to request authorization. 113 00:08:03,530 --> 00:08:06,200 So go ahead and build and run this one more time. 114 00:08:06,380 --> 00:08:11,810 Pull open your simulator and let's see if it requests our location suite. 115 00:08:11,810 --> 00:08:13,370 All right so it pulls it up. 116 00:08:13,400 --> 00:08:14,000 This is great. 117 00:08:14,030 --> 00:08:21,220 And it gives us the choice only while using the app always allow or don't allow the click always allow. 118 00:08:21,350 --> 00:08:24,940 And as soon as you do that you'll notice my location pops up right there on the map. 119 00:08:25,130 --> 00:08:26,550 That's exactly what we wanted. 120 00:08:26,560 --> 00:08:31,180 But we're a little bit too far out here we can't really see anything that's going on on the map. 121 00:08:31,310 --> 00:08:35,110 So we need to actually write a function now that's going to zoom us in. 122 00:08:35,350 --> 00:08:40,370 OK we're going to call it Center map on user location and basically what it's going to do is we're going 123 00:08:40,370 --> 00:08:45,820 to set a region that is about 1000 meters around where the user is and we're going to zoom the map in 124 00:08:45,820 --> 00:08:47,820 to show that whole region. 125 00:08:47,840 --> 00:08:48,890 Pretty cool. 126 00:08:49,250 --> 00:08:53,700 So to do that we're going to actually write this function in M-K map view delegates. 127 00:08:53,710 --> 00:08:56,260 It has to do with the map view and so let's do that. 128 00:08:56,300 --> 00:09:05,150 Let's write phunk center map on user location give it some curly brackets there. 129 00:09:05,150 --> 00:09:06,420 That looks awesome. 130 00:09:06,740 --> 00:09:12,050 And now we're going to do in order to center this on the user's location is we're going to need to create 131 00:09:13,700 --> 00:09:15,970 a constant for the coordinate. 132 00:09:15,980 --> 00:09:16,390 Right. 133 00:09:16,400 --> 00:09:20,340 So on our map view there's a coordinate here where this pin has been dropped. 134 00:09:20,360 --> 00:09:25,970 The only issue is that sometimes the location manager might be a little bit slower or faster when the 135 00:09:25,970 --> 00:09:26,990 app opens. 136 00:09:27,020 --> 00:09:31,040 So we're actually going to safely create a constant using a guard. 137 00:09:31,040 --> 00:09:35,200 Let k this make sure that there is a value of the coordinates. 138 00:09:35,210 --> 00:09:36,860 Otherwise it just returns. 139 00:09:37,190 --> 00:09:40,510 So if it doesn't work the first time it's going to just return. 140 00:09:40,520 --> 00:09:45,470 And then as soon as the map view starts updating the location we can call it the center which is pretty 141 00:09:45,470 --> 00:09:46,070 cool. 142 00:09:46,310 --> 00:09:53,330 So go ahead and type guard let cord in it and this is going to be equal to location manager and the 143 00:09:53,330 --> 00:09:56,650 location manager we can get the location right. 144 00:09:56,660 --> 00:09:59,000 So that's where the blue dot is where it's showing up. 145 00:09:59,390 --> 00:10:01,500 And then we can get the coordinates from that. 146 00:10:01,820 --> 00:10:02,060 OK. 147 00:10:02,060 --> 00:10:03,060 Very cool. 148 00:10:03,080 --> 00:10:03,960 Now for a guard let. 149 00:10:03,980 --> 00:10:04,700 We need to put. 150 00:10:04,700 --> 00:10:11,070 Else at the end meaning if there is no value here what we're going to do happens inside these brackets. 151 00:10:11,120 --> 00:10:12,110 And we're just going to return. 152 00:10:12,110 --> 00:10:16,730 Meaning we're going to exit out of this function until it can be called later when there definitely 153 00:10:16,730 --> 00:10:17,640 is a value. 154 00:10:17,810 --> 00:10:22,880 OK so this is basically a guard lead and this is a constant that we can use. 155 00:10:22,880 --> 00:10:29,450 So assuming there's a value assuming coordinate comes back something other than nyl we're going to create 156 00:10:29,480 --> 00:10:31,150 a coordinate region. 157 00:10:31,220 --> 00:10:35,320 So go ahead and type let coord in that region. 158 00:10:35,630 --> 00:10:40,860 And this is going to be equal to M-K coordinate region which you can see right here. 159 00:10:41,030 --> 00:10:46,340 Now if I put a parentheses here you can see that a co-ordinate region has a center which hint hint it's 160 00:10:46,340 --> 00:10:49,210 going to be the blue dot and it has a span. 161 00:10:49,580 --> 00:10:54,620 So the center of course is going to be the coordinate as you would expect. 162 00:10:54,860 --> 00:10:56,460 And the M.K. coordinates span. 163 00:10:56,480 --> 00:11:03,350 If I press enter here and then option click you can see that this comes from map kit geometry and basically 164 00:11:03,650 --> 00:11:10,690 the span is where we're going to set how wide we want our region to be how big. 165 00:11:10,850 --> 00:11:16,220 And in order to keep track of that we're actually going to just set a constant of the radius that we 166 00:11:16,220 --> 00:11:18,080 want this region to be. 167 00:11:18,080 --> 00:11:21,110 And so what I'm going to do is actually up here at the tippy top. 168 00:11:21,110 --> 00:11:25,220 I'm going to go ahead and create a constant called region radius. 169 00:11:25,310 --> 00:11:31,880 Now bear in mind this needs to be of type double and we're going to set that to be equal to 1000 meaning 170 00:11:31,880 --> 00:11:33,980 1000 meters. 171 00:11:33,980 --> 00:11:38,030 That way we can set a region that is 1000 meters wide 1000 meters tall. 172 00:11:38,030 --> 00:11:40,880 We're basically creating a circle around our user. 173 00:11:41,240 --> 00:11:47,420 So with our region radius in place go ahead and scroll back down to M-K coordinates span and the M.K. 174 00:11:47,420 --> 00:11:52,730 coordinates span is going to basically allow us to set how far of a radius we want our map view to be. 175 00:11:52,730 --> 00:11:54,080 So go ahead. 176 00:11:54,410 --> 00:11:57,710 At the end of M-K coordinates spand type dot net. 177 00:11:57,920 --> 00:12:00,340 And you'll notice that there is. 178 00:12:00,530 --> 00:12:04,180 It's asking for a latitude Delta and a longitude Delta. 179 00:12:04,430 --> 00:12:04,720 OK. 180 00:12:04,730 --> 00:12:06,530 So let's go ahead and delete that. 181 00:12:06,800 --> 00:12:11,030 And now the latitude Delta is going to be the amount of change over the map. 182 00:12:11,030 --> 00:12:16,790 So we're going to have it basically go from one point plus a thousand k so we can just go ahead and 183 00:12:16,790 --> 00:12:24,070 type region radius OK and then we're going to do longit to delta of region radius as well. 184 00:12:24,390 --> 00:12:29,310 OK so that's cool our coordinate coordinate region is set. 185 00:12:29,330 --> 00:12:34,710 And now what we need to do is we need to basically just ask the map view to set that region type map 186 00:12:34,720 --> 00:12:39,900 do you set region passen coordinate region. 187 00:12:40,220 --> 00:12:42,510 And we want it to be animated. 188 00:12:42,530 --> 00:12:42,810 OK. 189 00:12:42,860 --> 00:12:43,820 Easy is that. 190 00:12:44,090 --> 00:12:45,900 So our co-ordinate region is now done. 191 00:12:45,920 --> 00:12:51,770 We're setting this region on our map view and this way it should be able to go ahead and zoom in nicely 192 00:12:51,770 --> 00:12:56,000 right to where the user is with about 1000 meter radius around the user. 193 00:12:56,000 --> 00:13:00,890 So now we just need to know where to call this to center the map on the user's location. 194 00:13:00,890 --> 00:13:06,110 And that's actually going to be a part of C-L location manager delegate. 195 00:13:06,110 --> 00:13:12,320 So in order to do that we're going to call one of the built in functions called did change. 196 00:13:12,440 --> 00:13:12,830 Oh whoops. 197 00:13:12,860 --> 00:13:19,820 I probably should call location manager and then let's type authorization did change. 198 00:13:19,820 --> 00:13:20,230 OK. 199 00:13:20,450 --> 00:13:28,160 So this function here did change authorization status is called any time the map view changes authorization. 200 00:13:28,160 --> 00:13:35,540 So with that in mind if suddenly our map view gets approved right if we approve when in use location 201 00:13:35,540 --> 00:13:42,830 services we want to center the map it's not the action center map on user location whenever we approve 202 00:13:42,830 --> 00:13:42,940 it. 203 00:13:42,950 --> 00:13:44,930 It's going to center on the user. 204 00:13:45,020 --> 00:13:50,690 And that's actually why we use the guard let when we press the authorization. 205 00:13:50,690 --> 00:13:56,030 If the map for some reason was not yet loaded it would try to zoom in and it would crash because it 206 00:13:56,030 --> 00:13:57,020 doesn't have a coordinate. 207 00:13:57,040 --> 00:14:01,910 But we use the guard left to return just in case we're being very safe programmers and that's one of 208 00:14:01,910 --> 00:14:04,710 the wonderful things about Swift is that you can do that. 209 00:14:04,940 --> 00:14:06,560 So let's build and run. 210 00:14:06,560 --> 00:14:12,700 Let's see if this actually does center properly like we want credit we go it built. 211 00:14:12,710 --> 00:14:13,790 And let's take a look. 212 00:14:16,320 --> 00:14:22,350 How are we going to crash was that it says Invalid region center. 213 00:14:22,700 --> 00:14:23,360 OK that's good. 214 00:14:23,360 --> 00:14:26,690 And the span is a thousand. 215 00:14:26,690 --> 00:14:28,390 Let's take a look why. 216 00:14:28,460 --> 00:14:29,380 Interesting. 217 00:14:30,290 --> 00:14:35,900 We have an M-K coordinate region and the span is good. 218 00:14:38,380 --> 00:14:43,220 OK let's you know what let's Oh I think I know what's wrong. 219 00:14:43,220 --> 00:14:43,450 OK. 220 00:14:43,460 --> 00:14:44,800 M-K coordinate region. 221 00:14:44,810 --> 00:14:47,930 There's another one called with make with distance. 222 00:14:47,930 --> 00:14:48,230 Yes. 223 00:14:48,230 --> 00:14:48,400 OK. 224 00:14:48,410 --> 00:14:49,660 This is exactly right. 225 00:14:49,670 --> 00:14:52,650 Sorry guys I should have shown you this from the get go. 226 00:14:52,850 --> 00:15:00,290 M-K coordinate region make with distance allows you to use a distance length instead of a circular region. 227 00:15:00,290 --> 00:15:07,190 That's what I'm trying to do is to set a distance meaning a thousand meters in all directions longitudinally 228 00:15:07,280 --> 00:15:08,780 and latitude. 229 00:15:09,160 --> 00:15:11,040 I think those are real words anyway. 230 00:15:11,060 --> 00:15:15,120 So go ahead and pass in that coordinate coordinate. 231 00:15:15,710 --> 00:15:18,980 Sorry guys coordinate not to coordinate region. 232 00:15:18,980 --> 00:15:21,860 Now the latitudinal meters is going to be region radius. 233 00:15:21,860 --> 00:15:23,870 But remember this is just one way. 234 00:15:23,870 --> 00:15:28,970 So we actually need to multiply it by two in order to get 1000 thousand meters on the left and the right 235 00:15:28,970 --> 00:15:33,260 side of us and then let's do that again for the distance the other way. 236 00:15:33,260 --> 00:15:35,840 Region radius times 2.0. 237 00:15:35,840 --> 00:15:42,920 Now we have a region radius going 1000 this way and that way and this way in that way north east south 238 00:15:43,010 --> 00:15:45,080 and west and all around. 239 00:15:45,080 --> 00:15:46,530 Let's try this one more time. 240 00:15:46,550 --> 00:15:49,130 Let's go ahead and build and run this. 241 00:15:49,340 --> 00:15:53,340 And let's check to see if it can properly set our region and zoom in. 242 00:15:57,160 --> 00:15:58,390 All right look at that. 243 00:15:58,420 --> 00:16:05,010 It centered us right on our little dot and we have about 1000 meters on either side top to bottom. 244 00:16:05,020 --> 00:16:07,760 That's our little radius here that we're paying attention to. 245 00:16:07,810 --> 00:16:09,060 Super super cool. 246 00:16:09,070 --> 00:16:11,120 Looks like it's zooming in perfectly. 247 00:16:11,170 --> 00:16:16,090 The only thing is we now need to set it so that this button when we click the center button it should 248 00:16:16,090 --> 00:16:18,420 center our location back down to the middle. 249 00:16:18,640 --> 00:16:18,890 OK. 250 00:16:19,000 --> 00:16:20,410 That is the only thing. 251 00:16:20,590 --> 00:16:25,930 And to do that we're going to actually go into our action we created centerman button was pressed and 252 00:16:25,930 --> 00:16:29,220 we're going to check against the authorization status just like we did before. 253 00:16:29,410 --> 00:16:37,600 So go ahead and type if author status is equal to authorized always Or you can use the two straight 254 00:16:38,350 --> 00:16:39,190 straight slashes. 255 00:16:39,190 --> 00:16:45,590 I don't know what else to call them or authorization status is equal to when in use. 256 00:16:45,640 --> 00:16:50,510 So if it's authorized in any way we're going to go ahead and center the map on the user location. 257 00:16:50,740 --> 00:16:51,000 OK. 258 00:16:51,010 --> 00:16:55,340 Now let's try and build and run this and let's double check to make sure that that works. 259 00:16:55,360 --> 00:16:57,440 And then we're going to go ahead and move on to the next video. 260 00:16:59,040 --> 00:17:00,060 OK so we zoom in. 261 00:17:00,060 --> 00:17:01,280 That's lovely. 262 00:17:01,290 --> 00:17:02,610 Looks good. 263 00:17:02,610 --> 00:17:06,790 Let's go ahead and move the map and if I clicked this it should zoom. 264 00:17:06,810 --> 00:17:07,760 Yeah there we go. 265 00:17:07,830 --> 00:17:08,340 It works. 266 00:17:08,340 --> 00:17:10,080 It zooms in centers us. 267 00:17:10,290 --> 00:17:15,030 You might be noticing this looks a little messed up and I think that's just because I'm using the iPhone 268 00:17:15,330 --> 00:17:20,340 6 or iPhone 7 plus and I'm a little bit zoomed out if I zoom in. 269 00:17:20,340 --> 00:17:21,820 It looks a lot better. 270 00:17:22,470 --> 00:17:27,620 So when I click it it animates and it zooms right to the center that's super super cool. 271 00:17:27,630 --> 00:17:27,920 All right. 272 00:17:27,930 --> 00:17:29,770 So this works this is wonderful. 273 00:17:29,880 --> 00:17:33,840 In this video we have set it up so that we can get location services. 274 00:17:33,840 --> 00:17:38,380 We've given the user the power to choose always when in use or disallow. 275 00:17:38,520 --> 00:17:44,580 And we've also centered the map on the user's location using both a delegate method and the center map 276 00:17:44,580 --> 00:17:44,910 button. 277 00:17:44,910 --> 00:17:46,090 So very awesome. 278 00:17:46,170 --> 00:17:51,420 In the next video we're going to add a UI tap gesture recognizer so we can drop a pin exactly where 279 00:17:51,420 --> 00:17:53,560 we want on our map you see over there.
