寻找当前视图有没有想要的视图

-(UIView *)findView:(UIView *)aView withName:(NSString *)name{

Class cl = [aView class];

NSString *desc = [cl description];

NSLog(@"********%@",desc);

if ([name isEqualToString:desc])

return aView;

for (NSUInteger i = 0; i < [aView.subviews count]; i++)

{

UIView *subView = [aView.subviews objectAtIndex:i];

subView = [self findView:subView withName:name];

if (subView)

return subView;

}

return nil;

}
