I'm not sure, but where are you setting the frame of your activityIndicatorView? I've just tried this piece of code and it works perfect.

  activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
 [activityIndicator setCenter:CGPointMake(160, 240)];
 [activityIndicator startAnimating];
[window addSubview:activityIndicator];
UIButton* button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button setFrame:CGRectMake(100, 300, 120, 50)];
[button setTitle:@"press me" forState:UIControlStateNormal];
[button addTarget:self action:@selector(onBtnClk) forControlEvents:UIControlEventTouchUpInside];
[window addSubview:button];
[window makeKeyAndVisible];

and this is onBtnClk method

- (void) onBtnClk{
if([activityIndicator isAnimating]){
 [activityIndicator stopAnimating];
}else{
 [activityIndicator startAnimating];
}

}
