How to remove view from window?

Question

I am using Cocos2D for my main framework. In some cases, I want Cocos2D to load a nib file and have that be the view:

window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
TargetPlayerViewController *myController = [[TargetPlayerViewController alloc]initWithNibName:@"TargetPlayerViewController" bundle:nil];
[window addSubview:[myController view]];
[window makeKeyAndVisible];

This works as expected, and shows the TargetPlayerViewController. Wonderful!

What I need to know is: once that view has been loaded, how can I have the view remove itself? I've tried a few different ways, but all of them result in the program crashing.

To test I have a button on the view set up which triggers this method:

- (IBAction)GTFOnow:(id)sender {
    NSLog(@"GFTO");
    //window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    //[self.view removeFromSuperview];
    //[window makeKeyAndVisible];
}

GTFOnow is a method in TargetPlayerViewController. When it is called, the current subview (that was called in the Cocos2D code above) should be removed from the window.

"In this method the view should remove itself from the view". This is very confusing. I suppose you mean the view controller should remove the view from the window? — Felixyz

First of all, you shouldn't create a new window just because you want to remove a subview. Secondly, whatever else happens, this shouldn't cause the app to crash. In which class do you have the GTFOnowmethod? I suppose in the TargetPlayerViewController class?
