    copied!<p>i am tearing my hair out, I have migrated my old project to arc and I'm getting this error popping up : <em>*</em> Terminating app due to uncaught exception 'NSGenericException', reason: '-[UIPopoverController dealloc] reached while popover is still visible.'</p> <p>I have read through some threads and I'm confused, some say when using delegates use a weak reference but on the other hand when using popovers use a strong property reference, can someone give me an example of how best to use ARC and delegates with a popover that has a button inside that changes the background colour for example?</p> <p>From what I've read I keep hearing use an instance variable in my view controller, here it is in my main view controller:</p> <pre><code>@property (nonatomic, strong) UIPopoverController *currentPopover; </code></pre> <p>and the is the method implementation in the main view controller file:</p> <pre><code>- (IBAction)ShowPopTextColor:(id)sender { if (currentPopover == nil) { TimerTextColor *timerTextColor = [[TimerTextColor alloc]init]; timerTextColor.delegate =self; UIPopoverController *pop = [[UIPopoverController alloc]initWithContentViewController:timerTextColor]; [pop setDelegate:self]; [pop setPopoverContentSize:CGSizeMake(320, 240)]; [pop presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; //[pop release]; } else { [currentPopover dismissPopoverAnimated:YES]; currentPopover = nil; } } </code></pre> <p>here is my popup content header:</p> <pre><code>@protocol colorChooserDelegate -(void) colorSelected:(UIColor*)thecolor; @end @interface TimerTextColor : UIViewController{ id&lt;colorChooserDelegate&gt; delegate; IBOutlet UIButton *colorView; } - (IBAction)buttonTapped:(id) sender; @property (nonatomic,strong) id&lt;colorChooserDelegate&gt;delegate; @property (nonatomic,strong) UIButton *colorView; @end </code></pre> <p>What am i doing wrong?</p>
