Answer 1

Give your various UIButton instances different tag property values.

In your IBAction method -myMethod:, you might then do something like:

- (void) myMethod:(id)sender {
    switch (sender.tag) {
        case (firstButtonTag):
           doFooStuff;
           break;
        case (secondButtonTag):
           doBarStuff;
           break;
        // etc.
    }
}

The values firstButtonTag and secondButtonTag can be stored in an enum if you want to make this easy to maintain.
