開發中有的時候需要涉及當前視圖的父級視圖，可以通過UIResponder來獲取，有兩種實現方式:

UIView *next=sender;
while ([next superview]) {
    next=[next superview];
    UIResponder *nextResponder = [next nextResponder];
    if ([nextResponder isKindOfClass:[UIViewController class]]&&![nextResponder isKindOfClass:[UINavigationController class
 
]]) {
        Class cls=[nextResponder class];
        NSLog(@"ClassName:%@",cls);
    }
    NSLog(@"FlyElephant---%@",next);
    NSLog(@"FlyElephant---%@",nextResponder);
}

還有一種類似的實現方式如下:

for (UIView *next = [sender superview]; next; next = next.superview) {
    NSLog(@"UIView---%@",next);
    UIResponder 
 
*nextResponder = [next nextResponder];
    NSLog(@"UIResponder---%@",nextResponder);
}
