How to set my own ViewController class as the first screen (root view)

问题

I have created a windows based project in XCode using IPhone as target platform and then I added a ViewController Sub Class. Now I want to make my newly added class to be shown at first screen. What is the proper way to achieve it?

Regards.

回答1:

Modify your appdelegate, you'll find something like this:

[window addSubview:myView];
[window makeKeyAndVisible];

Change my view to the view you want to show first.

That is the correct way i found

first declare your view controller in appdelegate.h

SaveViewController *SaveController;

also

@property (nonatomic, retain) SaveViewController * SaveController;

then synthesize it in your appdelegate.m file

@synthesize SaveController;

now add the following lines of code in your application didFinishLaunching Method

SaveController = [[SaveViewController alloc]initWithNibName:@"SaveViewController" bundle:nil];

[window addSubview:[SaveController view]];


[self.window makeKeyAndVisible];

Thats all.. you are done :)
