Create a navigation-based application in xcode4.2

No navigation-based application exists in xcode4.2, instead of the master-detailapplication. When we create the application on the iPhone, we can get a navigation application.Program, Which is a uitabelview as the root view, but we prefer the version in the old version.

1. Create a master-detailapplication Program

2. Deleted the uitableview-based controller.

3. Create a mainwindow. XIB File

4. create our own rootviewcontroller, which inherits from uiviewcontroller.

The current project structure should be:

5. Modify appdelegate. h and appdelegate. M.

Appdelegate. h:

# Import <uikit/uikit. h>

@ Interface appdelegate: uiresponder <uiapplicationdelegate> {

Uiwindow * window;

Uinavigationcontroller * navigationcontroller;

}

@ Property (nonatomic, retain) iboutlet uiwindow * window;

@ Property (nonatomic, retain) iboutlet uinavigationcontroller * navigationcontroller;

@ End

Appdelegate. M:

Major changes:

-(Bool) Application :( uiapplication *) Application didfinishlaunchingwitexceptions :( nsdictionary *) launchoptions

{

[Self. Window addsubview: navigationcontroller. View];

[Self. Window makekeyandvisible];

Return yes;

}
