appdelegate

I'm trying to change the Status Bar color in my Swift app to white, but am hitting a brick wall. I have 3 ViewControllers that are each embedded in a NavigationController (could that be the issue? I've already tried to place the code in the NavigationController class.) I've tried both of the following pieces of code in the didFinishLaunchingWithOptions of my AppDelegate.swift file but neither worked. application.statusBarStyle = .LightContent and UIApplication.sharedApplication().statusBarStyle = .LightContent All that the Docs have to say about it is that UIBarButtonStyle is an Int and gave

I have a two-view login to my app where a user enters two views worth of info. After the user has entered that info I want change which view is the initial view controller, and have the login view be a settings-like page. How can I change the initial view controller after the user has passed a certain point in the app? For one of my apps, where I did similar to this, I have my "main" view controller check on viewDidLoad for a setting in the default settings that would indicate if the user had signed in. If they hadn't, I immediately pushed the loginViewController without animation and the user

I got the device token through didRegisterForRemoteNotificationsWithDeviceToken method. I wanted to use the device token in another method. I tried it in this way, In didRegisterForRemoteNotificationsWithDeviceToken method: str = [NSString stringWithFormat:@"%@",deviceToken]; // str is the NSString which is declared in the appDelegate.h file as global variable In didReceiveRemoteNotification method: NSLog(@"Device Token : %@",str); When i do like this the Device Token is returning as "nosniff". How can i store this device token in a global variable and use it in the other class or in other

I am trying to run a function in certain ViewController using AppDelegate func applicationDidBecomeActive(_ application: UIApplication) { ViewController().grabData() } But somehow the function does not seem to run at all when the app has become active after entering the app from the background. The function looks like this func grabData() { self._DATASERVICE_GET_STATS(completion: { (int) -> () in if int == 0 { print("Nothing") } else { print(int) for (_, data) in self.userDataArray.enumerated() { let number = Double(data["wage"]!) let x = number!/3600 let z = Double(x * Double(int)) self.money

I was reading Apple docs , when I found this sentence: The AppDelegate class contains a single property: window . var window: UIWindow? This property stores a reference to the app’s window. This window represents the root of your app’s view hierarchy. It is where all of your app content is drawn. Note that the window property is an optional , which means it may have no value (be nil ) at some point. What I don't understand is: why this property at some point could be nil? What's the case for it to be(come) nil? When you close your application, your app can still receive silentNotifications or

Having a problem following a few guides, specifically http://blog.originate.com/blog/2014/04/22/deeplinking-in-ios/ I'm setting the url scheme and it's working well to launch the app from another app, but passing in the host or url are not working as it seems it should. I'm using storyboards and interface builder for all the view layouts. The guide shows this openURL in appDelegate: -(BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation{ if([[url host] isEqualToString:@"page"]){ if([[url path]

What is the sequence of methods that get called when your app loads, especially for these methods: applicationDidFinishLaunching viewDidLoad viewWillAppear applicationDidBecomeActive awakeFromNib U could checkout this site http://www.cocoanetics.com/2010/07/understanding-ios-4-backgrounding-and-delegate-messaging/ & this flow chart of application. and check out this flow chart.... 来源： https://stackoverflow.com/questions/17498568/when-do-the-appdelegate-methods-get-called-in-relation-to-the-view-lifecycle-met
