Hey guys this is Caleb with dustups dot com.

2
00:00:10,470 --> 00:00:15,440
And again congratulations on finishing the core data section of the Iowa 11 course.

3
00:00:15,480 --> 00:00:16,190
Amazing work.

4
00:00:16,190 --> 00:00:21,910
So this video is a little challenge for you to make goalpost even cooler and even better.

5
00:00:22,050 --> 00:00:27,420
So as you know in goalposts we can create goals we can save them to our table view we can remove them

6
00:00:27,420 --> 00:00:29,150
we can set progress.

7
00:00:29,160 --> 00:00:33,360
Your challenge is to add an Undo feature.

8
00:00:33,960 --> 00:00:40,210
Your job is to figure out a way that you can add this view make it pop up whenever you delete a cell.

9
00:00:40,290 --> 00:00:42,620
So let's go ahead and let's go through the process.

10
00:00:42,630 --> 00:00:44,020
Eat healthy.

11
00:00:44,250 --> 00:00:46,460
A TERRIBLE go by the way it's not specific.

12
00:00:46,770 --> 00:00:48,230
And let's just say two.

13
00:00:48,510 --> 00:00:51,200
OK so let's say you finish this goal.

14
00:00:51,210 --> 00:00:53,490
It's complete and you want to get rid of it.

15
00:00:53,550 --> 00:00:55,470
So you press delete.

16
00:00:55,470 --> 00:01:01,590
But what you want to happen is you want it to show here goal removed then you want to be able to click

17
00:01:01,680 --> 00:01:05,660
undo and have it reappear in your table view.

18
00:01:05,670 --> 00:01:08,420
Now you have what you need to do this.

19
00:01:08,420 --> 00:01:09,530
I believe in you.

20
00:01:09,720 --> 00:01:10,670
This is your challenge.

21
00:01:10,680 --> 00:01:13,940
Add an Undo feature to goalpost.

22
00:01:14,010 --> 00:01:16,160
Amazing work again on the core data section.

23
00:01:16,260 --> 00:01:17,920
And let's head over to the next section now.
