00:00:00,390 --> 00:00:02,310

OK, so how did you find that task?



2

00:00:02,340 --> 00:00:08,190

Well, I've completed it here with basically three lines of code, but one important line and you'll



3

00:00:08,190 --> 00:00:11,170

notice that I can't actually swipe this down.



4

00:00:11,220 --> 00:00:13,020

I simply cannot dismiss it.



5

00:00:13,410 --> 00:00:21,320

But if I do my usual rubbish and I register that person, it will disappear.



6

00:00:21,720 --> 00:00:24,930

And how I've done that is I had to override the view.



7

00:00:24,930 --> 00:00:26,140

Did load, first of all.



8

00:00:26,400 --> 00:00:28,830

So this is a life-cycle call.



9

00:00:29,370 --> 00:00:34,100

The View, the view controller that we're loading goes through lifecycle.



10

00:00:34,110 --> 00:00:39,660

So first it gets called and then it gets initialized and then the view gets prepared and then the view



11

00:00:39,660 --> 00:00:42,860

loads, but it isn't shown and then the view appears.



12

00:00:43,290 --> 00:00:45,030

So at the point it loads.



13

00:00:45,030 --> 00:00:49,830

I know I have everything available to me that a view controller can do, but it's not yet shown.



14

00:00:50,080 --> 00:00:54,450

So before it shows, I get to say is modal in presentation.



15

00:00:54,450 --> 00:01:00,870

Now, modal means it just pops up on the screen and there's no way to dismiss it unless I plumb that



16

00:01:00,870 --> 00:01:01,830

in somehow.



17

00:01:02,070 --> 00:01:06,780

And of course with our login register items, we've already plumbed that in.



18

00:01:06,810 --> 00:01:13,650

So we don't need to do anything more and simply set that to true and then we can't actually swipe anything



19

00:01:13,650 --> 00:01:14,080

away.



20

00:01:14,490 --> 00:01:16,710

So that was the homework that was pretty simple.



21

00:01:17,220 --> 00:01:23,190

If you got stuck, it's probably because you didn't use the right terminology on Google when you were



22

00:01:23,190 --> 00:01:24,780

searching for this solution.



23

00:01:25,650 --> 00:01:27,410

Now, what did I use here?



24

00:01:28,200 --> 00:01:32,460

I use the words prevent view controller from dismissing.



25

00:01:33,400 --> 00:01:38,260

And I got loads and loads of Google hits, some are old, some of the code didn't work because it is



26

00:01:38,260 --> 00:01:44,650

that old, but someone said an iOS 13, we get this new popover view, the one that we're seeing within



27

00:01:44,650 --> 00:01:45,670

our particular app.



28

00:01:46,030 --> 00:01:50,430

And the way to stop it from swiping away is to just set that to true.



29

00:01:50,470 --> 00:01:51,340

That's the easy way.



30

00:01:51,580 --> 00:01:55,520

There are other ways of doing it, but we'll just do it the easy way.



31

00:01:55,600 --> 00:01:56,590

Thank you very much.
