如何在Swift中注册远程通知时获取设备令牌

Question

注册远程通知时，我无法收到设备令牌。我收到了警报消息"Do you want to allow App X to be able to send you notificaitons"，但是当我接受它时，didRegisterForRemoteNotifications函数未被调用。我试了下面的代码。

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { 
    // Override point for customization after application launch. 

    var types: UIUserNotificationType = UIUserNotificationType.Badge | 
     UIUserNotificationType.Alert | 
     UIUserNotificationType.Sound 

    var settings: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: types, categories: nil) 

    application.registerUserNotificationSettings(settings) 
    application.registerForRemoteNotifications() 

    return true 
} 

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) { 

    var characterSet: NSCharacterSet = NSCharacterSet(charactersInString: "<>") 

    var deviceTokenString: String = (deviceToken.description as NSString) 
     .stringByTrimmingCharactersInSet(characterSet) 
     .stringByReplacingOccurrencesOfString(" ", withString: "") as String 

    println(deviceTokenString) 

} 

我的配置文件和证书是有序的。

先后别人有这个问题？

因此，我在设备上运行我的应用一段时间，然后我回过头来看到application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) 已被称为蓝色，现在它就像一个魅力！我最好的猜测是，为什么会发生这种情况是因为证书和后台发生的所有其他事情都需要一段时间才能配置推送通知。因此，对于任何有同样问题的人，我建议给它一些时间然后再回来，在我的情况下，如果有任何帮助，花费大约12小时。

有时沙盒APNS下跌就像是昨天发生的，当时的代表们不要求设备令牌。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{ 
if([[UIDevice currentDevice] systemVersion].floatValue >= 8.0) 
{ 
    UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil]; 
    [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];  
} 
else 
{ 
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound|UIRemoteNotificationTypeBadge)]; 
} 
} 


- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken 
{ 
      //Your device token code 
} 

尝试实施以下方法检查：

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings 
{ 
    //register to receive notifications 
    [application registerForRemoteNotifications]; 
} 

//For interactive notification only 
- (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"]){ 
    } 
}
