iOS Development Project-02 adding sub-controllers and project tiering

First, add a sub-controller

1. Setting the root controller (custom)

Description: Analyze Sina Weibo application and observe its overall construction level. and the controller of the system can not meet the needs of the project development, here the project has the original controller deleted. Define a Tabbarviewcontroller class yourself. Let this class act as the root Controller for window windows.

YYAPPDELEGATE.M File Code:

1 #import "YYAppDelegate.h" 2 #import "YYTabBarViewController.h" 3  4 @implementation yyappdelegate 5  6-(BOOL) AP Plication: (uiapplication *) application didfinishlaunchingwithoptions: (nsdictionary *) launchoptions 7 {8   9    / /1. Creating Windows     Self.window=[[uiwindow alloc]init];11     self.window.frame=[uiscreen mainscreen].bounds;12     13     //2. Setting the root controller of a window//    Uitabbarcontroller *TABBARVC =[[uitabbarcontroller alloc]init];15//    SELF.WINDOW.ROOTVIEWCONTROLLER=TABBARVC;     self.window.rootviewcontroller=[[yytabbarviewcontroller alloc]init];17     //3. display window     [ Self.window makekeyandvisible];20     return yes;21}22         

2. Create a new four custom controller

Description: According to the Function module division, divides the project into four big parts, respectively is the homepage, the message, the discovery and "I", according to the project need, the custom four sub-controller, carries on the management to these four modules respectively.

Customize four controllers to inherit from Uitableviewcontroller

In the controller (Yytabbarviewcontroller), add four sub-controllers

3. Copy the required picture material into the project

Recommendation: When copying images, it is recommended to use a hard disk copy of the hard disk, that is, in the Finder.

4. Modify the System plugin

In the project, it is often used to classify (such as the use of a self-defined uiimage in this project), but when we use this classification method, we can only hint that the plugin may not have smart hints, then in this case you may try to modify the plugin.

(1) Find the installation path of the plugin in Xcode

Hint: Xcode plug-in Installation path:/users/User name/Library/Application Support/developer/shared/xcode/plug-ins

(2) Show Package Contents

(3) Modify the Plist file

Second, the implementation of the Code

III. Planning Project Document structure

The development of this project is divided into modules, the file structure is as follows:

Tip: In the construction of the structure, you can create a new group in the project, after the group is complete, drag the corresponding files to the corresponding group, but the group is a virtual folder, by viewing the code of the file can be found, on the hard disk is essentially no sub-folder.

Recommendation: Group directly on the hard disk to resolve this issue.
