IsKindOfClass not working properly iOS 7

The code below returns “YES” in iOS 5.0, 6.0, 6.1, etc., but returns “NO” in iOS 7.0. Do you have any idea about this? Is this an iOS 7.0 bug? Many thanks..

[view isKindOfClass:[SimpleLabel class]]

PS: "SimpleLabel" is a class inherited from UILabel.

---- UPDATE ----

Sorry for the incomprehensible question. :( I use the code above in the UITableViewCell class and add SimpleLabel , as shown below:

  [self addSubview:label];

I override the layoutSubviews function, the loop in self.subviews , but the [view class] always returns a UITableViewCellScrollView .

 -(void)layoutSubviews { [super layoutSubviews]; for (UIView*view in self.subviews) { if ([view isKindOfClass:[SimpleLabel class]]) { SimpleLabel*label = (SimpleLabel*)view;

UITableViewCell view hierarchy has changed a bit in iOS 7

On iOS <= 6, the hierarchy looks like

 <UITableViewCell> | <UITableViewCellContentView> | | <UILabel>

whereas in iOS 7 it looks like

 <UITableViewCell> | <UITableViewCellScrollView> | | <UIButton> | | | <UIImageView> | | <UITableViewCellContentView> | | | <UILabel>

(source: http://www.curiousfind.com/blog/646 )

When you add a subview, it is inserted into the UITableViewCellContentView , which is one level deeper than where you are looking.

isKindOfClass: working correctly, the problem is that you are going through the wrong set of subheadings.

By the way, this is a great example of why you should never rely on internal hierarchies of views: Apple can change them at any time.
