Question

Is there a way to have all UIButtons on a view use the same Touch Up Inside handler? Or perhaps set all the buttons to the same delegate using the Interface Builder?

Answer 1

Yes. Control drag the first button into the header file the way your normally would and create the action. Then in the .xib file, connect each of the other buttons to File’s Owner and choose the same action that you just created.

In the .xib file, look at the Attributes Inspector on the View pane. You can set the Tag for each button individually. Then you can use the following code…

- (IBAction)myButtons:(id)sender {

    switch ([(UIButton *)sender tag]) {
        case 0:
            // code for first button
            break;

        case 1:
            // code for second button
            break;

        case 2:
            // code for third button
            break;

        default:
            break;
    }
}
