如何通过一个view找到viewcontroller

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