继承UIResponder 类有:
1 AppDelegate
2 UIApplication
3 UIViewController
4 UIView
superView 取出来的类只是 [UIView class];
通过superView 在取一次Responder很有可能控制器,具体视文件结构来定
-(UIViewController* )nextControll{
for(UIView*view = [self superview];view ;[view superview]){
UIResponder*responder = [view nextResponder];
if( [responderisKindOfClass:[UIViewControllerclass]]) {
UIViewController* Vc= (UIViewController*)responder;
returnVc;
}
}
returnnil;
}
