如何根据View获取所在的Controller

- (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;
}
