Remote Notification iOS 8

Question

How can I get the Device Token for remote notification in iOS 8? I used the method didRegisterForRemoteNotificationsWithDeviceToken in AppDelegate in iOS < 8, and it returned the device token. But in iOS 8, it does not.

Answer 1

Read the code in UIApplication.h.

You will know how to do that.

First:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 

add Code like this

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) { #ifdef __IPHONE_8_0   UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert        | UIUserNotificationTypeBadge        | UIUserNotificationTypeSound) categories:nil];   [application registerUserNotificationSettings:settings]; #endif } else {   UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;   [application registerForRemoteNotificationTypes:myTypes]; } 

if you not using both Xcode 5 and Xcode 6 ,try this code

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {   UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIRemoteNotificationTypeBadge       |UIRemoteNotificationTypeSound       |UIRemoteNotificationTypeAlert) categories:nil];   [application registerUserNotificationSettings:settings]; } else {   UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;   [application registerForRemoteNotificationTypes:myTypes]; }

Second:

Add this Function

#ifdef __IPHONE_8_0 - (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {     //register to receive notifications     [application registerForRemoteNotifications]; }  - (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void(^)())completionHandler {     //handle the actions     if ([identifier isEqualToString:@"declineAction"]){     }     else if ([identifier isEqualToString:@"answerAction"]){     } } #endif 

And your can get the deviceToken in

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken 

if it still not work , use this function and NSLog the error

-(void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
