iOS UIAlertView in AppDelegate have to call Method in ViewController

[poke]

Hi,

i have a method called perform4 in the ViewController.m

-(void) perform4
{
 NSLog(@"perform4");
 UIStoryboard *mainStoryBoard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
ViewController4 *view4 = (ViewController4 *) [mainStoryBoard instantiateViewControllerWithIdentifier:@"ViewController4"];

[self.view removeFromSuperview];
[self release];

self.view = view4.view;
[self release];
}

this Method has to be called from my AppDelegate.m with this AlertView Button

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
 if(buttonIndex==0)
{
   NSLog(@"Button 0");

  
  //EVERYTHING I WILL PUT HERE DO NOT WORK OR MAKE A CRASH :/
  //like
  // ViewController *view1 = [[ViewController alloc]init];
  // [view1 perform4];
  // WHY DO THIS DONT WORK? 

}

Thanks

it works, when i call it from the viewcontroller.m , but not when i try to call it from the appdelegate.m - i need to know how to call it, to make everything work

can you help me please?

ok i realized this with

self.window.rootViewController.view = view4;
[self.window makeKeyAndVisible];

but i have now the problem to switch back, while

self.window.rootViewController.view = view;
[self.window makeKeyAndVisible];

let crash my app

Crash

Are you sure you should be calling [self release]? Twice?

That seems very bad. If you try to switch back to this view it will crash because the view controller has been improperly deallocated.

In Xcode, click on the menu "Product" in the menubar. Select the item "Edit Scheme". Under "Diagnostics", you should have "Enable Zombie Objects" checked off. If you do this, you will receive a warning whenever an object that has been dealloced is sent a message. (either because you released too often, as I suspect you did, or because you didn't retain as often as you should have.)
