I'm using Core Data with Cloud Kit, and have therefore to check the iCloud user status during application startup. In case of problems I want to issue a dialog to the user, and I do it using UIApplication.shared.keyWindow?.rootViewController?.present(...) up to now. In Xcode 11 beta 4, there is now a new deprecation message, telling me: 'keyWindow' was deprecated in iOS 13.0: Should not be used for applications that support multiple scenes as it returns a key window across all connected scenes How shall I present the dialog instead? This is my solution: let keyWindow = UIApplication.shared

I need your help in clarifying my understanding of the various states of an app. I am going to state my interpretation - but please feel free to correct me. 1) App is launched and running in the foreground: state = UIApplicationStateActive 2) User pushes home button: state = UIApplicationStateBackground (????). Debug stmt in my app shows it to be Active 3) User double-taps Home and kills the app: state = UIApplicationStateInactive If the value for case 2 is indeed Active, then when is the value set to Background? My location-based app relies on this values to take appropriate action for the

Is it possible to access the settings app from your own app via a button or whatever it may be in iOS 8. I heard that it got decrepitude in iOS 5, is that true? If not did the method change in iOS 8?

As of iOS 8, it is possible to take a user from your app directly into the Settings app. They will be deep linked into your app's specific Settings page, but they can back out into the top level Settings screen. If you're also supporting iOS 7 you'll need to check first if a specific string constant is present.

I want to convert a CGPoint from my UIView to UIWindow coordinates and have realized that UIApplication keyWindow is always nil; why is this? I have tried the convertPoint:toView: method from UIView. Please see this sample code I tried in the view controller in a template of Xcode (View application): - (void)viewDidLoad { [super viewDidLoad]; UIView *test = [[UIView alloc] initWithFrame:CGRectMake(40,40,250,250)]; [test setBackgroundColor:[UIColor redColor]]; [self.view addSubview:test]; CGPoint p = CGPointMake(100, 100); CGPoint np; np = [test convertPoint:p toView:[[UIApplication

I need to do something in applicationDidEnterBackground . But I need to differentiate which user action causes the "enter background": screen lock or home button press. I was using this code, which is from this post - How to differentiate between screen lock and home button press on iOS5? : UIApplicationState state = [application applicationState]; if (state == UIApplicationStateInactive) { NSLog(@"Sent to background by locking screen"); } else if (state == UIApplicationStateBackground) { NSLog(@"Sent to background by home button/switching to other app"); } It works fine on iOS6. but on iOS7
