iOS Activity Indicator

This is how it is done (example is using WebView)

I made some further changes so the indicator is more visible (by putting it inside an alert popup):

- (void)viewDidLoad {     [super viewDidLoad];         loadingAlert = [[UIAlertView alloc] initWithTitle:@"Loading..."                                                       message:@"\n"                                                      delegate:self                                             cancelButtonTitle:nil                                             otherButtonTitles:nil, nil];     activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];     [loadingAlert addSubview:activityIndicator]; } - (void) showLoadingAlert {     [loadingAlert show];         activityIndicator.frame = CGRectMake((x,y,w,h);     [activityIndicator startAnimating]; } - (void) dismissLoadingAlert {     [activityIndicator stopAnimating];     [loadingAlert dismissWithClickedButtonIndex:0 animated:NO]; }

Note that I set the frame after "show". This is because if I wanted to calculate x,y,w,h relative to the size of the loading alert frame, these values will only be non-zero after show.
