devicetoken

问题 I am using this code to get the Notification Center Device token. It was working in Swift 3 but not working in Swift 4.

问题 I am working on an iPhone app with Apple Push Notification integration. I have some doubts on this. If the user clicked "Dont Allow" button in the APNS registration alert, will our code still receives the Device Token from APNS? I have tested that when the user switched off the notification in iPhone notification, still the app receives the Device Token from APNS? It is correct? Can anyone please clarify these doubts? 回答1: In my understanding on APNS, it doesn't depend on the user's action

问题 I have two applications in one device. For iOS 7 both applications are sending different device tokens but for iOS 6 both apps are sending same device token. As per my understanding device token has to be same for all the application in one device. Is there something different in iOS7 than iOS 6? 回答1: UPDATE: I guess I read this one a bit too quickly.

问题 I know that there are lot of questions about this but I couldn't figure out the solution from those questions. I am getting null in a token from GCM. many people have done this using class, but I am doing this in background thread in same class. It returns null in regId. OnCreate if (checkPlayServices()) { gcm = GoogleCloudMessaging.getInstance(this); regid = getRegistrationId(context); if (regid.isEmpty()) { Log.e(TAG, "registering in background"); registerInBackground(); } else { Log.e(TAG,

问题 I want to send push notification to certain users only. From what I have gone through in Apple docs. The code to register for push notification is this - (void)applicationDidFinishLaunching:(UIApplication *)app { // other setup tasks here.... [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)]; } // Delegation methods - (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:

问题 If we reset an iPhone, the device ID remains the same. Is it the same for the device token? 回答1: I assume you are referring to the device token available to methods such as - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken If this is the case, then no, the device token can and will change . Quoted from Apples Local and Push Notification Programming Guide By requesting the device token and passing it to the provider every

问题 In my app I have different devices registered and for the Android ones I am storing the GCM Registration Id and for the iOS I am storing the device token (push notifications). I want to distinguish when a device is iOS or Android. What is the easiest way to do it? Do Android GCM RegIds start always with string "APA"? 回答1: In short no. If you need to distinguish between Android and iOS clients, include a platform identifier (eg: platform: Android) along with the InstanceID token when sending
