Question

I have many UIButtons which are linked to codes, but I wanted to have a method which works for all UIbuttons without connecting the method to the button, to play a sound when each button is pressed. Is there a way to detect when a general UIbutton is pressed? even if not linked to any code?

As mentioned in my comments, one option is by subclassing UIButton. You can create a subclass of UIButton and implement its init methods to add an action which will play a sound when pressed. This would be like the normal button actions but the target will be this custom subclass.

- (id)initWithFrame:(CGRect)frame {
    if (self=[super initWithFrame:frame]) {
        [self addTarget:self action:@selector(playSound) forControlEvents:UIControlEventTouchUpInside];
    }
    return self;
}

- (void)playSound {
  //play sound
}

Then use the button as,

CustomButton *aButton = [[CustomButton alloc] initWithFrame:aFrame];

If you are using xib or storyboard, you can change the class of button object from UIButton to CustomButton.
