Enabling and disabling multiple buttons in view issue

Question

I have a view with 12 buttons. I want to be able to perform the action's button just once when i tap it and then set that specific button disabled. When i tap on another button i want the same thing to happen + set the other buttons enabled. Is there a solution?

You can give to each button a tag, and when you tap on a button using method viewWithTag you can enable and disable each button:

When you create UIButton, you can add:

UIButton *button0 = ...
button0.tag = 0;

UIButton *button1 = ...
button1.tag = 1;

//and so on

In every action of the buttons, you must pass the id object like this:

-(void)tapButtonOne:(id)sender {

   //with this sender you can retrive the tag of the button clicked
   UIButton *button = sender;
   int buttonTag = button.tag

   //now you can check every button and enable the other that haven't the same buttonTag
   //with the first tag = 0 plus 12 the last tag will be 11 so i<12
   for (int i = 0; i<12; i++) {
     //self.view if you have added the buttons on self.view, otherwise you must write your view
     UIButton *buttonTemp = (UIButton *)[self.view viewWithTag:i];
     if(buttonTemp.tag != buttonTag) {

       buttonTemp.enabled = YES;
     }
     else {
       buttonTemp.enabled = NO;
     }
   }
}
