00:00:07,970 --> 00:00:13,460

Hey everybody welcome to the core data section of the Iowas 11 COURSE I'M SO EXCITED TO TEACH YOU.



2

00:00:13,470 --> 00:00:15,710

Chordata it's really really cool.



3

00:00:15,800 --> 00:00:21,280

It's going to allow you to basically have persistent storage in your app for all kinds of data.



4

00:00:21,290 --> 00:00:25,250

We're only going to be working with a few different kinds of data but I just want to show you the app



5

00:00:25,280 --> 00:00:27,690

I want to show you a demo of what you're going to build.



6

00:00:27,710 --> 00:00:30,920

It's called goal post and it's really cool let me show you here.



7

00:00:30,920 --> 00:00:32,710

We're going to go ahead and open up a goalpost.



8

00:00:32,720 --> 00:00:36,510

And as you can see it says welcome to goal post to begin create a goal.



9

00:00:36,530 --> 00:00:42,470

So we're going to click the Create Go button and now we're going to go ahead and type a goal here.



10

00:00:42,470 --> 00:00:46,790

I'm going to show you what happens when I toggle the keyboard and notice the button pops up it's pretty



11

00:00:46,790 --> 00:00:47,500

sweet.



12

00:00:47,780 --> 00:00:58,070

So let's go ahead and let's set a goal complete one coding challenge daily and let's do this as a long



13

00:00:58,070 --> 00:01:00,950

term goal OK click set.



14

00:01:00,950 --> 00:01:02,570

And how many points until complete.



15

00:01:02,570 --> 00:01:05,820

Let's say that we want to do this for three days.



16

00:01:05,810 --> 00:01:08,590

It's not really long term but it could be 30.



17

00:01:08,600 --> 00:01:14,630

But let's just set three for now and then click Create goal as you do that you'll see that it pops up



18

00:01:14,690 --> 00:01:17,320

in our table view here which is really cool.



19

00:01:17,330 --> 00:01:18,570

Now here's the coolest part.



20

00:01:18,620 --> 00:01:25,220

I'm going to go ahead and double tap the home button and I'm going to quit out of goalpost and watch



21

00:01:25,220 --> 00:01:27,840

what happens when I go back in.



22

00:01:27,950 --> 00:01:29,600

There's the magical Chordata stuff.



23

00:01:29,600 --> 00:01:31,830

It's persistent meaning it stays.



24

00:01:31,850 --> 00:01:36,380

Now what you can do is as you make progress towards your goal let's say that I completed my challenge



25

00:01:36,470 --> 00:01:42,020

for the day you can swipe to the left and tap at and you'll see the number goes up on the cell.



26

00:01:42,110 --> 00:01:48,530

I can keep doing this keep adding until I hit my third day which was our goal three right and you'll



27

00:01:48,530 --> 00:01:50,730

see it changes to complete.



28

00:01:51,050 --> 00:01:57,830

At this point I can add another goal if I want to like eat salad for lunch every week.



29

00:01:57,830 --> 00:02:03,200

How about that short term goal and let's just do it for two weeks just to go on a little bit of a health



30

00:02:03,200 --> 00:02:04,000

kick here.



31

00:02:04,220 --> 00:02:07,030

Press create goal and you'll notice we have a new goal.



32

00:02:07,430 --> 00:02:12,410

So let's go ahead and let's add that we're going to keep going until it's complete and when we're done



33

00:02:12,440 --> 00:02:17,090

if we want to get rid of it we can either press delete or we can swipe all the way over and it deletes



34

00:02:17,090 --> 00:02:19,010

automatically This is goalpost.



35

00:02:19,010 --> 00:02:24,290

It's an amazing Chordata app that we're going to build in the next couple videos so let's head over



36

00:02:24,290 --> 00:02:25,050

to the next one.



37

00:02:25,100 --> 00:02:25,730

Let's begin.
