iOS 获取UIView所在的VIewController

写程序的时候我们经常要封装代码,当你封装了一个UIView的子类里需要调用所在ViewController的方法用如下代码调取所在的VIewController

#pragma mark - 获取所在ViewController

- (UIViewController *)superViewController:(id)sender {

    for (UIView* next = [self superview]; next; next = next.superview) {

        UIResponder* nextResponder = [next nextResponder];

        if ([nextResponder isKindOfClass:[UIViewController class]]) {

            return (UIViewController *)nextResponder;

        }

    }

    return nil;

}
