Question

The issue is that in iOS 8, an NSLayoutConstraint that sets the inputAccessoryView's height equal to its initial frame height is installed automatically. In order to fix the layout problem, you need to update that constraint to the desired height and then instruct your inputAccessoryView to lay itself out.

- (void)changeInputAccessoryView:(UIView *)inputAccessoryView toHeight:(CGFloat)height {
    for (NSLayoutConstraint *constraint in [inputAccessoryView constraints]) {
        if (constraint.firstAttribute == NSLayoutAttributeHeight) {
            constraint.constant = height;
            [inputAccessoryView layoutIfNeeded];
            break;
        }
    }
}
