开发中有的时候需要涉及当前视图的父级视图，可以通过UIResponder来获取，有两种实现方式:
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);
}
还有一种类似的实现方式如下:
for (UIView *next = [sender superview]; next; next = next.superview) {
NSLog(@"UIView---%@",next);
UIResponder *nextResponder = [next nextResponder];
NSLog(@"UIResponder---%@",nextResponder);
}
