- (UIViewController*)GetViewController:(UIView*)uView
{
    for (UIView* next = [uView superview]; next; next = next.superview) {
        UIResponder* nextResponder = [next nextResponder];
        if ([nextResponder isKindOfClass:[UIViewController class]]) {
            return (UIViewController*)nextResponder;
        }
