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

问题描述

如何在 iOS 8 中获取远程通知的设备令牌?我在 iOS AppDelegate 中使用了 didRegisterForRemoteNotificationsWithDeviceToken 方法 didRegisterForRemoteNotificationsWithDeviceToken8，它返回设备令牌.但在 iOS 8 中，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

阅读 UIApplication.h 中的代码.

你会知道怎么做.

Read the code in UIApplication.h.

You will know how to do that.

首先:

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

添加这样的代码

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];
}

如果你没有同时使用 Xcode 5 和 Xcode 6，试试这个代码

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];
}

第二:

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

然后你就可以得到 deviceToken 了

And your can get the deviceToken in

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

如果还是不行，使用这个函数和NSLog error

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

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