How to create a multiple windows/views on the iPhone?

Question

Is it possible to create multiple view or window in a (Window based) iPhone app?

Answer 1

Yes kind of possible. Just create a new view using a view controller and create an instance of that view in your class. Then in an ibaction you could do some removing and adding subviews. That's just a quick and easy way tho, you can get into a lot more detail with how you would manage each view, etc.

Edit on Request: In your class, you would create an instance of it in the interface like so:

MyClass *myClass; (make sure to alloc and init in the init or awakeFromNib method)

Then make an instance of the app delegate in the ibaction like this:

MyAppDelegate *myAppDelegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate];

And then you can do this to switch from one view to another:

[self removeFromSuperView]; (or self.view in case this is a view controller)
[[myAppDelegate window] addSubview:myClass];

Answer 2

You can do something like the following to add a view programatically:

     //If you create controllers via XCode, just link them in the .h file with IBOutlet
     UIViewController *aViewController = [[UIViewController alloc] initWithNibName:@"YourNibName" bundle:[NSBundle mainBundle]];
     self.viewController = aViewController;
     [aViewController release];
     // Add the view controller's view as a subview of the window
     UIView *controllersView = [viewController view];
     [window addSubview:controllersView];
     [window makeKeyAndVisible];
