Don't allow user interaction when activity indicator view is visible

Question

I have a view which contains two views. One of those views contains two buttons and some text labels. The other one, with alpha set to 0.25, has an UIActivityIndicator

Answer 1

Though answer is replied in earlier response, just like to add for information purpose "[self.activityIndicatorView setHidden:YES];" no need to call this method explicitly, because startAnimating/stopAnimating already take care of this. I'm assuming you are using default value of "hidesWhenStopped" property.
