POHow to handle retain count for controllers saved in AppDelegate?
text
Body
copied!<p>MyAppDelegate is doing some background stuff and needs to refresh several views during this time, so I am saving a reference to each controller that gets created.</p> <pre><code>@interface MyAppDelegate : NSObject <UIApplicationDelegate> { SomethingController *currentSomethingController; } @property (nonatomic, retain) SomethingController *currentSomethingController; </code></pre> <p>This is done to open the controller:</p> <pre><code>- (void)openSomethingController { MyAppDelegate * app = [[UIApplication sharedApplication] delegate]; app.currentSomethingController = [[SomethingController alloc] init]; [self presentModalViewController:app.currentSomethingController animated:NO]; } </code></pre> <p>And this is called inside the controller to close it:</p> <pre><code>- (void)dismissSelf { MyAppDelegate * app = [[UIApplication sharedApplication] delegate]; [app.currentSomethingController release]; app.currentSomethingController = nil; [self dismissModalViewControllerAnimated:NO]; } </code></pre> <p>In MyAppDelegate the controllers is sending messages to the controller: </p> <pre><code>- (void)longRunningBackgroundTask { [currentSomethingController performSelectorOnMainThread:@selector(updateData) withObject:nil waitUntilDone:YES]; } </code></pre> <p>If I do Product->Analyse I get "potential leak" and "incorrect decrement" warnings. What would be the right way to do this or assuming my approach is okay, how do I tell the analysis tool to ignore those lines?</p>
