在iPhone 5和iPhone SE中獲取空設備令牌

Question

我沒有在iPhone 5（10.2.1）和SE（10.3.1）以及其他5個相關設備中獲取設備令牌，但是在所有iPhone 6（包括加號，SE）以及7和7+中也成功獲得了令牌。

這是我的注冊代碼

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()
    }
}

這是我收集令牌的代碼

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 )
}

有幫助嗎？

我在AppDelegate處理過didRegisterUserNotificationSettings

像這樣

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

這解決了@Lion提出的問題
