1 00:00:05,370 --> 00:00:06,730 Hey what's up guys. 2 00:00:06,740 --> 00:00:11,030 I'm Jacob blitzed with Def slips dot com in this lesson. 3 00:00:11,090 --> 00:00:16,110 We're going to get our duration timer working and formatted. 4 00:00:16,610 --> 00:00:18,130 So that's going to be really cool. 5 00:00:18,140 --> 00:00:23,820 Last time we got our distance finally working and we have it all formatted for meters to Miles. 6 00:00:23,990 --> 00:00:29,690 And obviously if you want kilometers you can just change that extension that we made and you have your 7 00:00:29,690 --> 00:00:31,410 kilometers. 8 00:00:31,460 --> 00:00:35,570 So in this lesson we need to start a duration timer right. 9 00:00:35,600 --> 00:00:43,390 And so that'll be in our Start Run we'll probably have like us start timer function. 10 00:00:43,400 --> 00:00:52,040 So inside of our Start Run why don't we just call start timer cool and underneath and run let's go ahead 11 00:00:52,040 --> 00:01:01,730 and make a function func start timer and opening and closing brackets and all right. 12 00:01:01,730 --> 00:01:05,460 So let's also we need a variable for our timer right. 13 00:01:05,510 --> 00:01:12,770 So underneath run distance Let's go ahead and just do var counter or you call it timer or whatever you 14 00:01:12,770 --> 00:01:15,030 want and set it to zero. 15 00:01:15,290 --> 00:01:20,630 So this is just going to be an integer and it's just going to keep track of seconds for us and then 16 00:01:20,630 --> 00:01:30,100 we are going to put an extension on type integer and do our whole formatting thing that we did before 17 00:01:30,460 --> 00:01:32,200 with meters to Miles. 18 00:01:32,200 --> 00:01:41,820 But we're going to format the timer from seconds to our minutes and seconds format. 19 00:01:41,840 --> 00:01:49,530 And so it'll be really cool just like our label if you remember I don't let's say let's just pull up 20 00:01:49,530 --> 00:01:51,420 our docs real quick. 21 00:01:52,830 --> 00:01:55,300 On run here we go. 22 00:01:55,610 --> 00:02:04,550 So basically we'll have you know are our hours minutes and seconds and that is we're going to format 23 00:02:04,640 --> 00:02:06,120 seconds to display it. 24 00:02:06,140 --> 00:02:08,600 All three of those. 25 00:02:08,610 --> 00:02:14,610 All right so we have our counter which is just an integer which is great. 26 00:02:14,720 --> 00:02:19,770 And then we need to create a our start timer function. 27 00:02:19,820 --> 00:02:30,660 So the first thing would be we need to format or we would need to start a timer right. 28 00:02:31,910 --> 00:02:40,020 So to create a timer we're going to need a another variable and we'll put it underneath a last location 29 00:02:40,020 --> 00:02:49,910 so var timer and timer is going to be equal to a instance of timer just like that. 30 00:02:49,930 --> 00:02:57,120 So we have our timer here and now in start timer we just have to set it up so to set up our timer. 31 00:02:57,160 --> 00:03:01,080 Let's go ahead and start timer function. 32 00:03:01,210 --> 00:03:08,550 Let's go ahead and do timer equals timer capital for timer scheduled timer. 33 00:03:08,830 --> 00:03:11,330 And we want it with interval. 34 00:03:11,740 --> 00:03:20,980 We want it not we don't want the repeating one we want to have the selector. 35 00:03:20,990 --> 00:03:23,730 Here we go this is what we want. 36 00:03:24,960 --> 00:03:34,770 OK so our interval is going to be one we want to count one value every time it gets called The Target 37 00:03:34,830 --> 00:03:44,320 self and our selector is going to be a function that we have to make right after this. 38 00:03:44,820 --> 00:03:48,870 But we'll call our function like Update counter. 39 00:03:49,770 --> 00:03:50,480 OK. 40 00:03:50,520 --> 00:03:56,890 And then the user info we don't need nyl and we want this to repeat Trews. 41 00:03:56,890 --> 00:04:01,980 So this is constantly going to be running when we're in this Visi and it's yelling at us because it 42 00:04:01,980 --> 00:04:02,530 doesn't know where. 43 00:04:02,570 --> 00:04:04,880 Update timer so underneath start timer. 44 00:04:05,100 --> 00:04:09,000 Let's make another function and call this update counter. 45 00:04:11,580 --> 00:04:19,600 Our cool and inside update counter are variable we created at the top. 46 00:04:19,600 --> 00:04:24,260 Instead it's a zero let's just say counter plus equals 1. 47 00:04:24,260 --> 00:04:28,680 So we're just going to add 1 to it every time this is called. 48 00:04:28,740 --> 00:04:30,610 Which is it makes sense right. 49 00:04:30,660 --> 00:04:35,910 And then we also want to take our duration label dot text. 50 00:04:36,060 --> 00:04:42,630 Whoops I can't get the period text and we want that to equal our counter. 51 00:04:42,630 --> 00:04:43,490 Right. 52 00:04:43,510 --> 00:04:44,930 All right cool. 53 00:04:45,670 --> 00:04:48,630 And we should probably have our start timer. 54 00:04:49,780 --> 00:04:55,440 Also set our duration level as well. 55 00:04:55,440 --> 00:05:01,500 So duration dot text equals counter that way. 56 00:05:01,500 --> 00:05:06,390 Start timers only called once but we want our label to be updated to zero right away right. 57 00:05:06,390 --> 00:05:12,040 Without using the default storyboard label. 58 00:05:12,070 --> 00:05:19,750 So with this being done we're going to now display segments on our Visi what doesn't. 59 00:05:19,790 --> 00:05:21,100 Oh I have to just 60 00:05:29,770 --> 00:05:31,330 you go. 61 00:05:34,680 --> 00:05:38,140 At once a string because it's a label. 62 00:05:38,280 --> 00:05:40,780 So we'll just print this for now. 63 00:05:41,130 --> 00:05:46,110 But the problem is it's just going to show one integer it's going to be seconds. 64 00:05:46,110 --> 00:05:46,490 Right. 65 00:05:46,500 --> 00:05:51,240 And that's not how we want to display but we'll make sure our timer works. 66 00:05:51,240 --> 00:05:53,090 So go ahead and press start. 67 00:05:53,100 --> 00:05:54,490 Run. 68 00:05:54,650 --> 00:05:59,260 And there we go our timer is counting up our distances move in. 69 00:05:59,360 --> 00:06:03,080 And if your distance isn't moving de-bug location city run. 70 00:06:03,080 --> 00:06:06,080 So our timer works but now we just need to format it. 71 00:06:06,080 --> 00:06:15,380 So it looks nice because if it gets over 60 seconds it's going to be pretty unreadable at a glance right. 72 00:06:15,410 --> 00:06:26,410 So let's go ahead and create our extension off of integer or we should extend and. 73 00:06:26,520 --> 00:06:28,450 So let's open our extensions. 74 00:06:28,710 --> 00:06:31,970 Class or file. 75 00:06:32,160 --> 00:06:41,310 And we want to now extent an extension off of int it opening and closing brackets and we will call this 76 00:06:41,790 --> 00:06:46,920 function format time duration 77 00:06:49,310 --> 00:06:50,590 2 string. 78 00:06:50,600 --> 00:06:58,140 So we're we're actually going to change our integer directly into a string before we return it. 79 00:06:58,140 --> 00:07:04,240 So we don't have to cast it in the label later it'll just make our lives a little easier. 80 00:07:04,460 --> 00:07:10,440 So let's go ahead and call this format time duration to string and we're returning a string. 81 00:07:10,970 --> 00:07:17,030 So this is also cool because you extending and right and you're not returning and you're actually returning 82 00:07:17,030 --> 00:07:19,670 a string so that's cool. 83 00:07:19,850 --> 00:07:21,890 And let's see we're passing. 84 00:07:21,900 --> 00:07:29,810 And so we're going to be formatting and integer and we need duration for hours minutes and seconds. 85 00:07:32,640 --> 00:07:43,410 So let's set up a variable for lat duration of hours equal self and we need to divide the integer to 86 00:07:43,410 --> 00:07:46,340 figure out hours by 3600. 87 00:07:46,770 --> 00:07:50,320 And that's because there are thirty six hundred seconds in an hour. 88 00:07:50,760 --> 00:07:59,720 And now we need to also create a variable for duration minutes and that is going to be equal to. 89 00:07:59,830 --> 00:08:02,430 We need a opening in parentheses. 90 00:08:02,430 --> 00:08:03,470 So we need self. 91 00:08:03,510 --> 00:08:08,030 And then we're going to use a modulus 3600. 92 00:08:08,220 --> 00:08:18,600 And what that does it's going to return how many times we can divide thirty six hundred into it. 93 00:08:20,810 --> 00:08:27,620 And then once we know that we can then divide by 60 which there are 60 Minutes in an hour and that will 94 00:08:27,620 --> 00:08:35,850 give us how many minutes are in the integer of seconds we just passed in and then we all are going to 95 00:08:35,850 --> 00:08:42,030 do the same thing for seconds so that duration seconds equal 96 00:08:44,910 --> 00:08:55,270 self modulus 3600 and then we also want to have this one return. 97 00:08:55,270 --> 00:08:56,200 How many times 98 00:09:00,740 --> 00:09:10,040 seconds can be divisible into the remaining value so we're going to do another modulus 60. 99 00:09:10,670 --> 00:09:18,410 And that is going to give us how many seconds are left in this integer we passed in and then we can 100 00:09:18,410 --> 00:09:25,810 do some cool things like if duration. 101 00:09:26,010 --> 00:09:30,540 Second chance is less than zero. 102 00:09:30,540 --> 00:09:33,760 That means it would actually return zero. 103 00:09:33,790 --> 00:09:40,230 Right well you still want it to return a value that we want to see so we can just return the string 104 00:09:40,260 --> 00:09:45,030 of 0 0 0 0 0 0. 105 00:09:45,030 --> 00:09:46,920 So that's what we want it to look like. 106 00:09:46,980 --> 00:10:01,660 If there is no value and then else we can also do like if duration hours isn't equal to zero or is equal 107 00:10:01,660 --> 00:10:02,850 to zero I'm sorry. 108 00:10:03,070 --> 00:10:08,030 Then we will return a string. 109 00:10:08,110 --> 00:10:08,650 Whoops. 110 00:10:08,680 --> 00:10:10,120 I'm having struggles here. 111 00:10:10,690 --> 00:10:23,170 A string of type format and the way you format a string now is you create a string and you do a percent 112 00:10:23,170 --> 00:10:23,690 sign. 113 00:10:23,710 --> 00:10:25,700 And then we want two places. 114 00:10:25,720 --> 00:10:30,980 So we always want if only like a single integers return like one or two. 115 00:10:31,120 --> 00:10:36,970 We want to make sure the second below far left field still has a value in it. 116 00:10:37,090 --> 00:10:44,330 And so we are going to put a 0 0 here and that means it'll always be filled with a 2. 117 00:10:44,440 --> 00:10:46,460 Or I mean I'm sorry. 118 00:10:47,020 --> 00:10:50,920 We always want two spots in this field right. 119 00:10:51,100 --> 00:10:54,230 And if there is only one it will put a zero there. 120 00:10:54,340 --> 00:10:55,610 That's what that means. 121 00:10:55,780 --> 00:10:57,510 And then we'll put our colon. 122 00:10:57,730 --> 00:11:00,940 And we want the same thing as 0 2. 123 00:11:01,150 --> 00:11:06,070 And we also need Deese there because they are type double. 124 00:11:06,360 --> 00:11:13,400 And then we just end our quotation and then arguments we pass in here since duration ours is zero. 125 00:11:13,410 --> 00:11:18,530 We just pass and duration minutes and duration seconds. 126 00:11:19,230 --> 00:11:26,220 And so this will get passed here and then duration seconds will get passed here and then so if duration 127 00:11:26,250 --> 00:11:28,540 hours isn't equal to zero. 128 00:11:28,800 --> 00:11:38,500 We want to return all three locations with the values so format opening and closing parentheses percent. 129 00:11:38,520 --> 00:11:43,120 0 2 d Colan percent 0 2 D. 130 00:11:43,160 --> 00:11:47,600 Colon and percent zero D. 131 00:11:49,040 --> 00:11:58,950 And then our arguments would be duration hours duration minutes and duration seconds. 132 00:12:00,380 --> 00:12:04,870 And that will return our formatted label for us. 133 00:12:04,880 --> 00:12:13,190 So now let's go ahead and go back to our current current run Visi and where the counter is let's just 134 00:12:13,190 --> 00:12:22,670 delete our our string where we can add the variable in and just call counter and we can say Dot. 135 00:12:22,730 --> 00:12:31,250 And we want to format time duration to string and then same in our update counter counter data format 136 00:12:31,250 --> 00:12:33,170 time duration 2 string. 137 00:12:33,380 --> 00:12:35,250 And let's go ahead and run this. 138 00:12:35,270 --> 00:12:41,400 And we should now see our cool label being updated and formatted properly. 139 00:12:45,690 --> 00:12:52,210 All right so now if we just press Start Run There we go with that. 140 00:12:52,220 --> 00:12:59,090 Our seconds are there and minutes will fill in there and our hours are missing until the run would get 141 00:12:59,090 --> 00:13:01,100 that long of an hours would appear. 142 00:13:01,100 --> 00:13:02,450 So that's really cool. 143 00:13:03,970 --> 00:13:05,350 So we are getting there guys. 144 00:13:05,350 --> 00:13:10,660 I'm going to call this video done before we are there let's go ahead and pull up our terminal and make 145 00:13:10,660 --> 00:13:23,050 sure we commit this so get ad period get commit Desch am and we got our duration timer functioning. 146 00:13:23,710 --> 00:13:30,900 All right sweet guys in the next run or in the next lesson we are going to get our average pace working. 147 00:13:31,060 --> 00:13:37,630 So if you guys want to stretch your abilities you should try to get that working before starting the 148 00:13:37,630 --> 00:13:38,640 next lesson. 149 00:13:38,890 --> 00:13:40,590 And then if you get stuck. 150 00:13:40,630 --> 00:13:44,250 Watch the next lesson and I will help you figure it out. 151 00:13:44,260 --> 00:13:44,530 All right. 152 00:13:44,530 --> 00:13:45,730 So I will see you in the next lesson.
