Best Solution

Create:

spinner = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
[spinner setCenter:CGPointMake(kScreenWidth/2.0, kScreenHeight/2.0)]; // I do this because I'm in landscape mode
[self.view addSubview:spinner]; // spinner is not visible until started

Start:

[spinner startAnimating]; 

Stop:

 [spinner stopAnimating];

When you're finally done, remove the spinner from the view and release.
