How to access Object ID Identity attribute?

Question

1. In the IB under Identity tab you can find an attribute called "Object ID". I can not find a way to get hold of this ID from code. Oh, and I know about the tag attribute but it's not what I need.

2. I essentially would like to get the unique object ID for a UIComponent that was touched on the sceen. I already have the UITouch object.

Answer 1

For UIView I normally use the tag property.

- (IBAction) buttonPressedid) sender {
NSLog(@"tag: %i", [sender tag]);
}

I'm pretty sure you can set the tag property in IB :)

Answer 2

The Object ID in Interface Builder is only an internal book-keeping value used by IB when deserializing/serializing XIB files, and does no longer exist when the Application runs.

You want to use tag, or alternately, a property/outlet.
