Question

i’m writing an ap for which, when you press on the button, the button should be disabled for a random amount of time between 0-10seconds and after that, the button becomes active again. However, while the button is disabled, if the user clicks, the click seems to just be queued up waitingg for the button to be enabled and the click will be processed. how would i disable and not enqueue user clicks?

-(void)buttonPressed{
    NSLog(@"Button pressed!");
    button.userInteractionEnabled=false;
    sleep(rand()%10);
    progLabel.text=@"button is enabled!";
    button.userInteractionEnabled = true;
}

I’m assuming you are using a button that derives from UIControl (UIButton?). You can take advantage of its existing enabled property. Setting the property to NO will ignore all touch events. See this link for information regarding UIControl.

Also, another issue I see in your example is your sleep() function. I’m not familiar with that function, but it could be blocking the main thread. Be cautious. Instead, you should use an NSTimer. After each interval, you might do this: button.enabled = !button.enabled for a toggle effect.
