Why is presentModalViewController hindering UITextField responses?

Question

Any uitextfield I add to a view which is presented from another view controller with presentModalViewController:animated: does not respond to any touch events (like the keyboard doesnt display when the uitextfield is tapped) also if i use [textField becomeFirstResponder] to force the keyboard to display, the only time this works is in the viewDidLoad method of the view controller

Anyone know why the uitextfield is not responsive whatsoever when i use presentModalViewController:animated: to display the view controller which the uitextfield is on?

Answer 1

after much trouble i came to find that

-(BOOL)canBecomeFirstResponder {    
    return YES; 
}

was hidden in my code somewhere, this for some reason was not allow the textfield to become first responder if i added the view via the presentModalViewController:animated: method
