I need to add a gesture (move, rotate, scale) to a UIButton.

I'm not sure I understand what you mean about adding a gesture. Right now, your buttons aren't set up to do anything at all.

I created the button in code, but I don't know how to use it.

You need to add a target and action to your button. When a button is tapped, it sends an action message to some other object, which is its target. To set up a button, you need to add a target and action using the -addTarget:action:forControlEvents: method inherited from UIControl. If you want the button to send a move message to the same object that's creating the button, you'd change your addButton method to include this:

[buttonImage1 addTarget:self action:@selector(move) forControlEvents:UIControlEventTouchUpInside];
