Question

I want to iterate thru all controls existing in a View on iOS when the view is loaded.

Also, it would be acceptable to have a callback that is called when these controls are initialized.

How can I obtain this?

Answer 1

To iterate through subviews (controls) in a parent view, call the parent view’s -subviews method:

for (UIView *subview in [parentView subviews]) {
    /* do something with subview */
}

You could subclass the control, creating a custom control. Here, you override the custom control view’s initializer method. In this method, you would call the parent’s initializer, and add your custom code.
