Hi there and welcome back to Section Twelve of this IRS bootcamp.

2
00:00:05,370 --> 00:00:10,950
So this section is about table views and collection views and it's actually one of our most important

3
00:00:10,950 --> 00:00:17,310
sections simply because almost every real application out there at least benefits from a table view

4
00:00:17,790 --> 00:00:25,230
a table view in general is a scrolling view that has a prototype cell that that cell can repeat itself

5
00:00:25,230 --> 00:00:31,890
so many many times every ten days repeats a brand new set of data gets populated and we end up seeing

6
00:00:31,920 --> 00:00:38,850
a difference an example of that the simplest one is an email application that you have all of the emails

7
00:00:38,880 --> 00:00:44,730
they all have a subject a little part of the body of the email and then the next cell repeats not for

8
00:00:44,730 --> 00:00:45,540
another email.

9
00:00:45,900 --> 00:00:51,600
Now what table views do which is a little bit difficult to do it manually is that they get rid of the

10
00:00:51,600 --> 00:00:52,720
use it.

11
00:00:52,740 --> 00:00:58,860
So if a cell is not currently within the view it gets deleted and a memory that was allocated for it

12
00:00:59,100 --> 00:01:00,500
it also frees up.

13
00:01:00,570 --> 00:01:05,460
We will see more about this and I will go through the details of that process for you as we go through

14
00:01:05,460 --> 00:01:08,640
the different lessons as an overview in this section.

15
00:01:08,640 --> 00:01:13,860
We will talk about table view controllers and table views as a standalone outlets.

16
00:01:13,890 --> 00:01:16,560
We'll talk about customizing table view cells.

17
00:01:16,560 --> 00:01:22,080
We'll talk about search controllers both within table views and outside table views.

18
00:01:22,230 --> 00:01:27,720
And then we'll talk about collection view controllers collection views cells as well as a very important

19
00:01:27,720 --> 00:01:31,180
topic which is the floor and the layout of a collection view.

20
00:01:31,180 --> 00:01:35,120
I will also show you how to use the master detail template up.

21
00:01:35,190 --> 00:01:37,960
So a pretty full on section.

22
00:01:38,040 --> 00:01:38,910
Let's get started.
