ios ui object check for text property

Question

I need to check if some object has text property. For example it can be an UIButton or an UILabel. But there is an issue between properties that display text for an UIButton and for an UILabel.

This is the difference:

For an UIButton we set text using setTitle: method, but for an UILabel we using another one named setText:

What I need to do with this:

I need to get all subviews and if these subviews have text property I need to change this property value with some text.

So of course I can check class of object and setup needed property, but maybe we have another approach to do it without checking class of object.

for (id item in [self.view subviews])
{
    if ([item respondsToSelector:@selector(text)])
        [item setText:@"text"]; // change text for UILabel
    else if ( [item respondsToSelector:@selector(setTitle:forState:)])
        [item setTitle:@"text" forState:UIControlStateNormal]; // change text for UIButton
}

Thanks for response. this is really work solution. Unfortunately, I understand that we can't using just one property for setting text cause of differences in ui objects property. but this one of few solutions that's working great.
