For instance I have created a view with 50 sequential buttons named btn1-btn50. If I want to address these buttons and make some changes to them in a loop how can I address the controls with a string name?
The typical way to get a view in a hierarchy is to call [parentView viewWithTag:] to get the view. If you give the buttons tag values from 1 to 50 you can use that to access the buttons.
If for some reason you need strings, you will have to create a custom subclass of UIButton that has a name member, assign a name to that member, then later iterate through the view hierarchy searching for an instance of your custom class with a name matching your search criteria.
