IPHONE: For UITableView -- changing to next view takes time, how to show UIActivityIndicatorView?

So, my UITableViewCell has UITableViewCellAccessoryDetailDisclosureButton, and when somebody clicks on it it make long time just to show next view screen... so I want to show some "rolling wait image" (UIActivityIndicatorView ?) say next to UITableViewCellAccessoryDetailDisclosureButton in this cell开发者_开发百科, but how do I do it right? How to use UITableViewCellAccessoryDetailDisclosureButton properly?

Thank you.

You can use a UIActivityIndicator as a UITableViewCellAccessory like so:

UIActivityIndicatorView *activityView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
[activityView startAnimating];
cell.accessoryView = activityView;
[activityView release];
