远程通知的iOS 8 [英] Remote Notification iOS 8

问题描述

我怎样才能在iOS 8远程通知设备令牌？
我在iOS版中所使用的的AppDelegate 方法 didRegisterForRemoteNotificationsWithDeviceToken ; 8，它返回的设备令牌。但在iOS 8的，它没有。

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.

推荐答案

您会知道该怎么做。

首先：

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

添加code这样的

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];
}

如果您不能同时使用X code 5和X code 6 ，试试这个code

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];
}

二：

添加此功能

#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

和您可以得到deviceToken

And your can get the deviceToken in

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

如果它仍然无法正常工作，使用此功能与的NSLog在的错误的

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

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