appdelegate

I think to know what the App Delegate does. It has some nice methods like -applicationDidFinishLaunching which will be called when the app has finished launching, and so on. But what's that actually? Is that some object instantiated in the UIApplicationMain function? And how does it work that every class in my app has access to that App Delegate object? Is there any good graph on the net that visualizes these relationships? In Cocoa, a delegate is an object that another object defers to on questions of behavior and informs about changes in its state. For instance, a UITableViewDelegate is

I want to open a specific view controller when a user clicks on the received push notification message, but when I receive a push notification message and click the message, only the application opens, but it does not redirect to a specific view controller. My code is -(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo { if (applicationIsActive) { UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Bildirim" message:[NSString stringWithFormat:@"%@ ",[[userInfo objectForKey:@"aps"] objectForKey:@"alert"]] delegate:self

I am working on push notifications. I wrote the following code for fetching a device token. - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. // Add the view controller's view to the window and display. [self.window addSubview:viewController.view]; [self.window makeKeyAndVisible]; NSLog(@"Registering for push notifications..."); [[UIApplication sharedApplication] registerForRemoteNotificationTypes: (UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)]; return

First times doesn't work "Null" ( before open App in iPhone ) and some times doesn't work but i want one loop or timer for repeat this request for get result : here is my code - (void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void (^)(NSDictionary *))reply { // Temporary fix, I hope. // -------------------- __block UIBackgroundTaskIdentifier bogusWorkaroundTask; bogusWorkaroundTask = [[UIApplication sharedApplication] beginBackgroundTaskWithExpirationHandler:^{ [[UIApplication sharedApplication] endBackgroundTask:bogusWorkaroundTask

What I am trying to do is click a button (that was created in code) and have it call up a different view controller then have it run a function in the new view controller. I know it could be done relatively easily in IB but that isn't an option. An example of what I want to do would be if you had two view controllers one with a splash screen of house. The other view controller had a walk through of the house on it that you could go through all the rooms in a set order. The splash screen would have buttons for each room that would allow you to jump to any point on the walk through. You can

I'm doing the Facebook integration tutorial, I want to show my MainViewViewController if the user has a valid token for the current state otherwise I want to show LoginViewController. MainViewAppDelegate.m - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { if (FBSession.activeSession.state == FBSessionStateCreatedTokenLoaded) { // To-do, show logged in view } else { // No, display the login page. [self showLoginView]; } return YES; } - (void)showLoginView { UIStoryboard *mainstoryboard = [UIStoryboard storyboardWithName:@

In my AppDelegate there is a problem I do not understand. RootViewController initially called ViewController and I changed it name. The application is formed by many ViewController then I have introduced a UINavigationController. Why this error comes?
