Undo an IBAction?

I am trying to press a UIBarButtonItem and perform an action, which it does. When It does I'm changing the name of the title of the BarButtonItem. That way if I hit it again I want to Undo the action it performed rather than coding everything out to change it back. Here is an example of my code.

- (IBAction)MyAction:(id)sender{

if([[MyButton title] isEqualToString:@"Test1"]){

//My Action is performed.

    [MyButton  setTitle:@"Test2"];
    [[undoManager prepareWithInvocationTarget:self] MyAction:?];
    [undoManager setActionName:@"UndoLastAction"];


}else if ([[MyButton title] isEqualToString:@"Test2"]){

    [MyButton setTitle:@"Test1"];
    [[undoManager prepareWithInvocationTarget:self]MyAction:?];
    [undoManager setActionName:@"UndoLastAction"];
}

}
Solution

  • Never mind, it's easier just to re-run the original code to "Undo" the action.
