Title Body

Im stuck trying to animate a table view smoothly which has an autolayout contraint. I have a reference to the constraint "keyboardHeight" in my .h and have linked this up in IB. All i want to do is animate the table view with the keyboard when it pops up. Here is my code: - (void)keyboardWillShow:(NSNotification *)notification { NSDictionary *info = [notification userInfo]; NSValue *kbFrame = [info objectForKey:UIKeyboardFrameEndUserInfoKey]; NSTimeInterval animationDuration = [[info objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue]; CGRect keyboardFrame = [kbFrame CGRectValue]; CGFloat height = keyboardFrame.size.height; [UIView animateWithDuration:animationDuration animations:^{ self.keyboardHeight.constant = -height; [self.view setNeedsLayout]; }]; } The thing is the animation block is instantaneous and I see white space appear before the keyboard has finished its animation. So basically I see the white background of the view as the keyboard is animating. I cannot make the animation last for as long as the keyboard is animating. Am i approaching this the wrong way? Thanks in advance!
