Find all controls of a type in a UIView

Question

I am looking for a way to automatically localize texts on buttons/textfields etc and for this method I need to find all (for example) UIButton's on a UIView.

I tried the following 2 methods, but they both do no work like I want them to work:

for (UIView* subView in self.view.subviews)
{
    NSLog(@"object class : %@", [subView class]);

    if ([subView isMemberOfClass:[UIButton class]])
        NSLog(@"Button found!");
}

The problem with this piece of code is that a RoundedRectButton does not match the UIButton class, while it really is just a UIButton.

I also tried the following:

for (UIButton* button in self.view.subviews)
{
// Do my stuff
}

But the stupid thing is, is that cocoa-touch actually just lists all subviews in that for-loop (also the UITextFields etc).

Is there a way to actually just get all UIButtons from a view? Or do I really need to find controls by looking at their selectors.

Answer 1

the first method is correct, except you need to change isMemberOfClass function to isKindOfClass:

isKindOfClass: Returns a Boolean value that indicates whether the receiver is an instance of given class or an instance of any class that inherits from that class.
