Control more than one button using tags

I have 28 buttons in my application. I need to control them in a single function. All I want to do is make all the buttons visible. I gave tags to the buttons. I tried it with a for loop but I couldn't do it how can I solve this problem?

(IBAction)btnAction:(id)sender{

UIButton *btnPressed = (UIButton *)sender;

NSUInteger i=btnPressed.tag;

for(i=0; i<29; i++)
{
    btnPressed.hidden=NO;

}

}

You can create a single IBAction method, check tag values and then do what you want to do 

- (IBAction)btnAction:(id)sender{
     UIButton *btnPressed = (UIBUtton *)sender;

    // Check button tags and write code accordingly //
  }

Instead of tags, use an IBOutletCollection. So now you have a single NSArray pointing to all of the buttons. Now just cycle through that NSArray.
