Question

I am trying to add a UIActivityIndicator to my custom view (programmatically). I am using the following code. But I dont see anything on the screen. Any idea why ?

Thanks.

UIActivityIndicatorView *activityIndicator=[[[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(75, 395, 200, 200)] autorelease];
[activityIndicator setActivityIndicatorViewStyle:UIActivityIndicatorViewStyleWhiteLarge];
activityIndicator.center=self.view.center;
[self.view addSubview:activityIndicator];

UIActivityIndicator has its hidesWhenStopped property equal to YES by default – that is it is hidden if you do not start animating it. So to make it appear on the screen try one of the following (whichever is more suitable for you):

1. set hidesWhenStopped property to NO
2. start animating it (using -startAnimating method)
3. comment “activityIndicator.center=self.view.center;”
