iOS 之 获取View所在控制器

1. UIResponder

UIViewController *uvc;

    UIResponder* nextResponder = [self.superview.superview.superview nextResponder];

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

        uvc = (UIViewController*)nextResponder;

    }

2.获取当前屏幕中present出来的viewcontroller

- (UIViewController *)getPresentedViewController

{

    UIViewController *appRootVC = [UIApplication sharedApplication].keyWindow.rootViewController;

    UIViewController *topVC = appRootVC;

    if (topVC.presentedViewController) {

        topVC = topVC.presentedViewController;

    }

    return topVC;

}
