00:00:07,730 --> 00:00:12,950

Hey everybody this is Caleb with Dev soapstar calm and in this video we're going to fix that dismissal



2

00:00:12,950 --> 00:00:18,800

error that we had in the last video where we dismissed finished goals Visi but instead of dismissing



3

00:00:18,800 --> 00:00:24,170

two goals Visi it dismissed back on top of create goal VC which we did not want.



4

00:00:24,170 --> 00:00:29,530

Once we leave that controller we want to leave it forever and dismiss back down to goals.



5

00:00:29,540 --> 00:00:35,630

VC So in this video we're going to fix that by modifying or you view controller extension so go ahead



6

00:00:35,660 --> 00:00:38,660

and pull open your X code project and go there now.



7

00:00:38,770 --> 00:00:45,020

Do you view controller XTi And what we're going to do is we're going to create a modification of present



8

00:00:45,020 --> 00:00:46,310

detail now.



9

00:00:46,340 --> 00:00:55,130

The issue is that we are presenting create goals VC like so let me show you in the simulator here we



10

00:00:55,130 --> 00:01:01,400

are presenting it just like so we're typing something and now we're calling present detail again.



11

00:01:01,400 --> 00:01:05,080

So we are presenting this view controller on top of this one.



12

00:01:05,320 --> 00:01:06,530

OK that's fine.



13

00:01:06,530 --> 00:01:13,300

But the issue is that when we give it some points like one and we press create goal it's dismissing.



14

00:01:13,310 --> 00:01:19,910

But since this is the one that presented it it is dismissing back to this one and not the view controller



15

00:01:20,120 --> 00:01:21,080

that we want.



16

00:01:21,200 --> 00:01:26,720

So we're going to write a function that's actually going to dismiss create goals Visi and then instantiate



17

00:01:26,720 --> 00:01:32,630

the new View Controller from goals AVC so that when we actually dismiss to create our goal at the very



18

00:01:32,630 --> 00:01:40,460

end like so like this when we press create goal it's actually going to dismiss all the way back down



19

00:01:40,520 --> 00:01:42,020

to the home view.



20

00:01:42,020 --> 00:01:49,230

The goals VC so to do that go ahead and type phunk present secondary detail.



21

00:01:49,610 --> 00:01:57,320

And of course we're going to need a view controller to present of type UI view controller and we're



22

00:01:57,320 --> 00:01:58,760

going to give it some curly brackets.



23

00:01:58,760 --> 00:02:06,170

Now the thing is this is going to be the exact same transition the duration the type the subtype.



24

00:02:06,170 --> 00:02:12,080

The only thing that's going to change is that we're going to first create a.



25

00:02:12,530 --> 00:02:18,140

The only thing that changes is that we are first going to create a reference to the presented view controller



26

00:02:18,560 --> 00:02:24,200

meaning we're going to create a reference to whatever view controller is currently presenting.



27

00:02:24,380 --> 00:02:28,820

We're going to dismiss that one and then upon the completion we're going to add the animation to the



28

00:02:28,820 --> 00:02:29,230

new one.



29

00:02:29,240 --> 00:02:33,650

So we're basically going to remove and animate and present the new one.



30

00:02:33,650 --> 00:02:35,750

All at the same time with this function.



31

00:02:35,870 --> 00:02:37,470

So go ahead and paste this in.



32

00:02:37,790 --> 00:02:43,040

And now we're going to do is we're going to basically create a constant that's going to hold our presented



33

00:02:43,040 --> 00:02:44,700

view controller.



34

00:02:44,930 --> 00:02:49,740

If you go into any view controller you can go ahead and find which one presented it by calling presented



35

00:02:49,740 --> 00:02:53,750

a view controller so let's use guard lead to create this by typing.



36

00:02:53,870 --> 00:02:57,750

Guard let presented view controller.



37

00:02:58,580 --> 00:03:02,460

And we're going to set that to be equal to the presented view controller.



38

00:03:02,450 --> 00:03:06,410

Now this is the view controller that is presented by this view controller.



39

00:03:06,410 --> 00:03:07,020

OK.



40

00:03:07,430 --> 00:03:13,210

So let's say that we call present secondary detail on Create Goals.



41

00:03:13,210 --> 00:03:20,030

VC we are going to go ahead and this is basically just a reference that references that controller.



42

00:03:20,150 --> 00:03:21,120

OK.



43

00:03:21,230 --> 00:03:24,720

Now if that doesn't work of course we're going to need to return.



44

00:03:24,920 --> 00:03:30,320

But assuming that it does work assuming we have a presented view controller we're going to go ahead



45

00:03:30,350 --> 00:03:36,630

and call presented view controller dismiss and we're going to go ahead and call animated false.



46

00:03:36,680 --> 00:03:41,510

Right because we're overriding the animation now now the completion is where things matter.



47

00:03:41,510 --> 00:03:47,390

Once it has properly dismissed meaning once it's gone and there's no animation we're going to go ahead



48

00:03:47,390 --> 00:03:54,200

and call self view window layer just like we did earlier and we're going to add our transition.



49

00:03:54,350 --> 00:03:54,920

OK.



50

00:03:55,100 --> 00:03:57,160

Which our transition is the same as before.



51

00:03:57,200 --> 00:03:59,780

We're presenting it from the left to the right.



52

00:04:00,050 --> 00:04:02,330

So let's pass that in transition.



53

00:04:02,600 --> 00:04:05,850

And the key is still KCA transition.



54

00:04:06,170 --> 00:04:07,030

That's great.



55

00:04:07,250 --> 00:04:10,580

But then what we're going to do is we're going to present the view controller we've passed in.



56

00:04:10,580 --> 00:04:15,380

So first we're going to dismiss it then we're going to add in the new transition and present the new



57

00:04:15,380 --> 00:04:15,980

one.



58

00:04:15,980 --> 00:04:23,150

So basically at the same time we are setting up goals Visi to actually present the new View Controller.



59

00:04:23,300 --> 00:04:31,340

So go ahead and call self at present and we're going to call you controller to present your controller



60

00:04:31,430 --> 00:04:32,370

to present.



61

00:04:32,630 --> 00:04:35,990

Animated is false because remember we're overwriting the animation.



62

00:04:36,170 --> 00:04:38,810

And at this point the completion doesn't matter.



63

00:04:38,870 --> 00:04:44,170

So we need to call present secondary detail we need to think where we need to call that from.



64

00:04:44,390 --> 00:04:52,340

We are first presenting create goals we see then from Create Goals VC we want to dismiss to the goals



65

00:04:52,340 --> 00:04:56,630

Visi while also simultaneously animating a new view controller on top.



66

00:04:56,630 --> 00:05:04,850

So now go into Create Goals Visi and instead of saying that create goals VC is doing the presenting.



67

00:05:04,850 --> 00:05:06,210

Get rid of this altogether.



68

00:05:06,350 --> 00:05:08,050

We're not presented from goals.



69

00:05:08,050 --> 00:05:13,950

VC we're going to instead go ahead and get the presenting the controller meaning the view controller



70

00:05:13,950 --> 00:05:16,260

that's presenting this one which is goals.



71

00:05:16,410 --> 00:05:23,460

The base VC we want and we're going to call present secondary detail from the presenting View Controller.



72

00:05:23,760 --> 00:05:29,300

So to do that go ahead and type finish goal.



73

00:05:29,310 --> 00:05:31,260

So to do that go ahead and type finish go.



74

00:05:31,290 --> 00:05:31,960

VC.



75

00:05:32,040 --> 00:05:37,920

So now we are saying goals VC dismiss this view controller and then present the new one at the same



76

00:05:37,920 --> 00:05:38,570

time.



77

00:05:38,820 --> 00:05:40,020

Let's go ahead and build and run.



78

00:05:40,110 --> 00:05:41,400

Let's go check to see if that works.



79

00:05:41,400 --> 00:05:44,190

And this should properly fix our dismissal error.



80

00:05:45,670 --> 00:05:54,860

All right cool so press add goal eat salad and let's make it long term press next and so you probably



81

00:05:54,860 --> 00:05:57,730

noticed at the same time it dismissed and animated.



82

00:05:57,740 --> 00:05:59,140

K that's cool.



83

00:05:59,150 --> 00:06:01,010

Now press 2 maybe.



84

00:06:01,000 --> 00:06:06,290

And when you press create goal watch what happens it properly dismisses to our goals.



85

00:06:06,290 --> 00:06:07,880

VC that's what we want.



86

00:06:07,880 --> 00:06:10,670

And it says it successfully save data double cool.



87

00:06:10,670 --> 00:06:12,080

So that's still working.



88

00:06:12,140 --> 00:06:14,390

Our dismissal now works perfectly.



89

00:06:14,390 --> 00:06:16,040

And awesome guys this is great.



90

00:06:16,040 --> 00:06:19,060

So I just wanted to fix that little air before we moved on.



91

00:06:19,250 --> 00:06:22,940

Let's go ahead and let's fetch our data from core data in the next video.



92

00:06:22,940 --> 00:06:28,100

Let's save it and let's fill an array with goals so that we can actually set up our table view here



93

00:06:28,100 --> 00:06:30,890

with all kinds of cool stuff I'll see in the next video.
