ios - 在iPhone 5和iPhone SE中获取空设备 token

我没有在iPhone5（10.2.1）和SE（10.3.1）以及其他5个相关设备中获得设备令牌，但也成功地在所有iPhone6（包括plus、SE）和7以及7+中获得令牌。
这是我注册的代码

func registerForPushNotification(let application: UIApplication) {
    let notificationTypes: UIUserNotificationType = [UIUserNotificationType.Alert, UIUserNotificationType.Badge, UIUserNotificationType.Sound]
    let pushNotificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: nil)
    application.registerUserNotificationSettings(pushNotificationSettings)

    application.applicationIconBadgeNumber = 0

    if pushNotificationSettings.types != .None {
        application.registerForRemoteNotifications()
    }
}

这是我收集代币的代码

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

    let characterSet: NSCharacterSet = NSCharacterSet( charactersInString: "<>" )
    let deviceTokenString: String = ( deviceToken.description as NSString )
        .stringByTrimmingCharactersInSet( characterSet )
        .stringByReplacingOccurrencesOfString( " ", withString: "" ) as String
    print( deviceTokenString )
}

有什么帮助吗？

最佳答案

我在我的didRegisterUserNotificationSettings中处理过AppDelegate
这样地

func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) {
    if notificationSettings.types != [] {
        application.registerForRemoteNotifications()
    }
}
