ios - 无法使用 swift 在 iPhone 6 中注册远程通知

Question

我正在使用以下代码为我的应用注册远程通知

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    let notificationSettings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: categories)
    application.registerUserNotificationSettings(notificationSettings)
    application.registerForRemoteNotifications()
    return true
}

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    print("token: \(deviceToken)")
}

func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
    print("Error : Fail to register to APNS : \(error)")
}

对于 iPhone 6，它不会调用方法 didRegisterForRemoteNotificationsWithDeviceToken 或 didFailToRegisterForRemoteNotificationsWithError，对于其他设备，如 5c/4s，它正在注册并打印 deviceToken

最初我认为这是操作系统问题，但后来，我检查了具有相同版本 9.3.2 的其他设备，它有效。

有人遇到同样的问题吗？

把这段代码写在 didFinishLaunchingWithOptions 中用于远程通知。我认为它会工作正常

if #available(iOS 8.0, *) {

    let userNotificationTypes:UIUserNotificationType = ([UIUserNotificationType.Alert, UIUserNotificationType.Badge, UIUserNotificationType.Sound])

    if UIApplication.sharedApplication().respondsToSelector("isRegisteredForRemoteNotifications") {


        // iOS 8 Notifications
        let settings:UIUserNotificationSettings = UIUserNotificationSettings(forTypes: userNotificationTypes, categories: nil)
        UIApplication.sharedApplication().registerUserNotificationSettings(settings)
        UIApplication.sharedApplication().registerForRemoteNotifications()


    } else {

        // iOS < 8 Notifications

        UIApplication.sharedApplication().registerForRemoteNotificationTypes([.Badge, .Sound, .Alert])

    }
    print("Push notifications setup complete")

}

快乐编码。
