Immediately starting new UIViewController from a viewcontroller

When the UIViewController starts, I want to start another UIViewController immediately. This doesn't work:

-(void) awakeFromNib {
    UIViewController *newcontroller = [[[UIViewController alloc] init] autorelease];
    ...
    [self presentModalViewController:newcontroller animated:YES];
}

In order for this to work, I have to do afterDelay for a method, like so:

-(void) awakeFromNib {
    [self performSelector:@selector(startNewController) withObject:nil afterDelay:0.5];
    [super init];
}
-(void) startNewController {
    UIViewController *newcontroller = [[[UIViewController alloc] init] autorelease];
    ...
}

Is it possible to get it to work without delay?

Solution

  • Call startNewController in your viewDidAppear method instead, that happens because your viewController is not totally loaded when you try to present the modal viewController, so that's why it works when you wait.
