Hi, I am having a problem with accessing public variable 'activity', which is a UIActivityIndicatorView type, see class declaration below in QuickStartViewController.h:

@interface QuickStartViewController : UIViewController <ABPeoplePickerNavigationControllerDelegate> {
@public
IBOutlet UIActivityIndicatorView *activity;

}

@property (nonatomic, retain) UIActivityIndicatorView *activity;

@end

The function is called from another class:

#import "QuickStartViewController.h"
@interface NumberValidator : QuickStartViewController....

See below:

- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
[activity startAnimating];
NSLog(@"This function is called, but [activity startAnimating] still doesn't work...");
}

Note: [activity startAnimating] works fine when called within the QuickStartViewController class

Do you have any suggestions as to why [activity startAnimating] is not working?
