Change UI control height after keyboard

Question

I've got this code to shrink and move my controls when the keyboard opens:

-(void)keyboardWillShow:(NSNotification *)notification {
    NSValue *value = [notification.userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey];
    NSTimeInterval interval = 0;
    [value getValue:&interval];

    CGSize keyboardSize = [[notification.userInfo objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;

    [UIView animateWithDuration:interval animations:^{
        self.composeBarBottomConstraint.constant = (-1) * keyboardSize.height;
        [self.view layoutIfNeeded];
    }];
}

This works perfect with the normal keyboard, but when I tap the emoji keyboard button the UI controls position isn't where it should be (offset upwards) and jumps rather than animating - making me think the values I retrieve from [notification userInfo] is wrong with the emoji keyboard.

Any ideas what's going on here?

What happens if you try to use `UIKeyboardFrameEndUserInfoKey` instead of `UIKeyboardFrameBeginUserInfoKey`? — Azat, Mar 27 '16 at 18:02

Replace UIKeyboardFrameBeginUserInfoKey to UIKeyboardFrameEndUserInfoKey. This key contains the information about keyboard size after all animations that system will perform. You can read more in this answer
