IOS: Using UITableView to create a table application walkthrough (2) Loading and displaying data from a plist file

A very simple walkthrough of table loading and display is described above. Some friends may say, this also said is simple, can be a bit complicated?

Don't worry, as a programmer, keep in mind that no matter how complex applications evolve from simple applications.

This article is based on the above, the application is extended to introduce the following content:

1. Data structure definition;

2. Loading and displaying data from plist files;

3. Display the Avatar in the table and adjust the table style;

4. Use the data model.

I. Data structure definition

In the previous walkthrough, an array was defined with Nsarray to provide tabular content, but in practice this functionality is far from satisfying the actual usage requirements.

In the previous article, we mentioned that we would like to do a maintenance of "Weibo concern people" application. So for the attention of people, a name clearly does not meet the needs of our application.

1. Click the right mouse button in "My Focus", select "New Group" in the pop-up menu, and enter "Data" as the name of the new group, as shown in the following figure:

2. Click the right mouse button on "Data", select "New File ...", then select "Resource" "Property List" and click "Next" to see the following image:
