how to determine in how to determine in UIApplicationDidBecomeActiveNotification whether it is the initial app launch?whether it is the initial app launch? that is the initial start up of the application, as opposed to subsequent DidBecomeActive's due to the application being put in background and then to foreground (e.g. user goes to calendar then back to your app) In your applicationDidFinishLaunching:withOptions: put this: [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"alreadyLaunched"]; [[NSUserDefaults standardUserDefaults] synchronize]; Then, in didBecomeActive : if ([

As mentioned before - I'm an Objective-C newbie of the first order but having read 4 physical books on the subject and a bucket-load of ebooks and documentation I still can't find what I'm looking for. I have a top-level content view controller that wants to configure its view property from the physical dimensions of the window property of the application delegate. This is something that several people have already asked questions on. ( [UIScreen mainScreen] doesn't cut it for reasons already aired many times before on this forum). Therefore, the logical approach would be for the content view

application: didReceiveRemoteNotification: fetchCompletionHandler: is different from application: didReceiveRemoteNotification: How? from the docs: Unlike the application:didReceiveRemoteNotification: method, which is called only when your app is running, the system calls this method regardless of the state of your app. If your app is suspended or not running, the system wakes up or launches your app and puts it into the background running state before calling the method. If the user opens your app from the system-displayed alert, the system calls this method again so that you know which

I want to call a function in applicationDidEnterBackground this function is defined in other controller. I have made an object to access it but it seems that function is getting killed when called. Here is the function it basically calculates the distance and postes a notification -(void)calculateDistance { for (NSMutableDictionary *obj in placeName) { CLLocation *userLocation = [[AppHelper appDelegate] mLatestLocation]; CLLocation *annotation1 = [[CLLocation alloc] initWithLatitude:[[obj objectForKey:@"Lat"]doubleValue] longitude:[[obj objectForKey:@"long"]doubleValue]]; CGFloat distanceTemp

I feel that UIApplicationBackgroundRefreshStatusDidChangeNotification introduced in iOS 7 is of little use without supporting UIApplication delegate method. Because, the app is not notified when user has switch ON the background refresh state for my app. This is my notification handler... - (void)applicationDidChangeBackgroundRefreshStatus:(NSNotification *)notification { NSLog(@"applicationDidChangeBackgroundRefreshStatus with notification info = %@ and refresh status = %d", notification, UIApplication.sharedApplication.backgroundRefreshStatus); if (UIApplication.sharedApplication

iOS SDK 4.2 includes a new UIApplicationDelegate method called application:openURL:sourceApplication:annotation: . It is a replacement for application:handleOpenURL: and offers more information about the calling application: not only do we get the bundle identifier of the calling app, but also, in the annotation argument, A property-list object supplied by the source application to communicate information to the receiving application. Great, this should offer a lot of opportunities for a more direct interaction between multiple third-party apps! The only problem is: how do I invoke this
