PushKit未构思凭据

Question

我在这里挣扎了一段时间，这可能是我的错误，但我在任何地方都找不到，这是一个答案。

我在某些方面实现了PushKit，但没有一种是有效的。

我添加了正确的后台模式，以正确的方式实现了回调，didUpdatePushCredentials通常被调用.

但是，credentials: PKPushCredentials!变量给了我一个错误指针..。不算零.不是零..。什么都没有..。它根本没有价值..。它被分配了垃圾..。出于这个原因..。我收到EXC_BREAKPOINT.

我试过三种不同的装置..。同样的行为..。

我已经为VoIP Push创建了证书.

我用不同的方式做过：

• 通过在didRegisterForRemotePushNotification之后创建void对象
• 通过创建推送注册表而不注册远程推送通知.
• 通过创建包含主队列、全局队列和自定义队列的注册表。

一切都一样..。

这是密码：

extension AppDelegate : PKPushRegistryDelegate {

func registerForVoipPush() {

    self.registry = PKPushRegistry(queue:nil)

    if self.registry != nil {

        self.registry!.delegate = self
        self.registry!.desiredPushTypes = Set<String>(arrayLiteral: PKPushTypeVoIP)
    }

    //let notificationSettings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories:nil)
    //UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings)
}

func pushRegistry(registry: PKPushRegistry!, didUpdatePushCredentials credentials: PKPushCredentials!, forType type: String!) {

    //print out the VoIP token. We will use this to test the nofications.
    NSLog("voip token: \(credentials.token)")

    if credentials != nil {

        let username = NSUserDefaults.standardUserDefaults().objectForKey("username") as? String
        if username != nil {

            ServerDefinitions.subscribeForPush(username!, token: NSString(data: credentials.token, encoding: NSUTF8StringEncoding) as! String, callback: { (retMsg) -> Void in

                print(retMsg)
            })

        }
    }

}

func pushRegistry(registry: PKPushRegistry!, didReceiveIncomingPushWithPayload payload: PKPushPayload!, forType type: String!) {

    let payloadDict = payload.dictionaryPayload["aps"] as? Dictionary<String, String>
    let message = payloadDict?["alert"]

    //present a local notifcation to visually see when we are recieving a VoIP Notification
    if UIApplication.sharedApplication().applicationState == UIApplicationState.Background {

        let localNotification = UILocalNotification();
        localNotification.alertBody = message
        localNotification.applicationIconBadgeNumber = 1;
        localNotification.soundName = UILocalNotificationDefaultSoundName;

        UIApplication.sharedApplication().presentLocalNotificationNow(localNotification);
    }

    else {

        dispatch_async(dispatch_get_main_queue(), { () -> Void in

            print("Incoming Call")
        })
    }

    NSLog("incoming voip notfication: \(payload.dictionaryPayload)")
}

func pushRegistry(registry: PKPushRegistry!, didInvalidatePushTokenForType type: String!) {

    NSLog("token invalidated")
}

}

编辑：

请注意，上面的代码是AppDelegate的扩展，它只用于分隔代码，因此它更容易读懂。

我还在AppDelegate上添加了var registry : PKPushRegistry?，为了使其工作，您必须在代码中的某个地方调用registerForVoipPush()。在我的例子中，我是从一个按钮上做的。

请帮帮我!

我遇到了同样的问题，我通过在启动VoIP注册之前添加一个经典的Push实现来解决这个问题.我想苹果想要确保你先向用户询问基本的推送，并在授权你处理更多的无声voip信息之前得到用户的支持.

启用应用程序的推送通知.

​

然后，这是整个生成的AppDelegate文件，非常类似于您的文件：

import UIKit
import PushKit


@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


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

        //Enable all notification type.
        let notificationSettings = UIUserNotificationSettings(forTypes: [UIUserNotificationType.Alert, UIUserNotificationType.Badge, UIUserNotificationType.Sound] , categories: nil)

        //register the notification settings
        application.registerUserNotificationSettings(notificationSettings)


        NSLog("app launched with state \(application.applicationState.stringValue)")

        return true
    }



    func applicationWillResignActive(application: UIApplication) {

    }

    func applicationDidEnterBackground(application: UIApplication) {

    }

    func applicationWillEnterForeground(application: UIApplication) {

    }

    func applicationDidBecomeActive(application: UIApplication) {
        // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
    }

    func applicationWillTerminate(application: UIApplication) {
        // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.

        NSLog("app terminated")
    }


}


extension AppDelegate {

    func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) {

        //register for voip notifications
        let voipRegistry = PKPushRegistry(queue: dispatch_get_main_queue())
        voipRegistry.desiredPushTypes = Set([PKPushTypeVoIP])
        voipRegistry.delegate = self;

        NSLog("didRegisterUserNotificationSettings")
    }
}

extension AppDelegate: PKPushRegistryDelegate {


    func pushRegistry(registry: PKPushRegistry!, didUpdatePushCredentials credentials: PKPushCredentials!, forType type: String!) {

        //print out the VoIP token. We will use this to test the nofications.
        NSLog("voip token: \(credentials.token)")
    }

    func pushRegistry(registry: PKPushRegistry!, didReceiveIncomingPushWithPayload payload: PKPushPayload!, forType type: String!) {

        let payloadDict = payload.dictionaryPayload["aps"] as? Dictionary<String, String>
        let message = payloadDict?["alert"]

        //present a local notifcation to visually see when we are recieving a VoIP Notification
        if UIApplication.sharedApplication().applicationState == UIApplicationState.Background {

            let localNotification = UILocalNotification();
            localNotification.alertBody = message
            localNotification.applicationIconBadgeNumber = 1;
            localNotification.soundName = UILocalNotificationDefaultSoundName;

            UIApplication.sharedApplication().presentLocalNotificationNow(localNotification);
        }

        else {

            dispatch_async(dispatch_get_main_queue(), { () -> Void in

                let alert = UIAlertView(title: "VoIP Notification", message: message, delegate: nil, cancelButtonTitle: "Ok");
                alert.show()
            })
        }

        NSLog("incoming voip notfication: \(payload.dictionaryPayload)")
    }

    func pushRegistry(registry: PKPushRegistry!, didInvalidatePushTokenForType type: String!) {

        NSLog("token invalidated")
    }
}

extension UIApplicationState {

    //help to output a string instead of an enum number
    var stringValue : String {
        get {
            switch(self) {
            case .Active:
                return "Active"
            case .Inactive:
                return "Inactive"
            case .Background:
                return "Background"
            }
        }
    }
}

作为@JBA，我忘记激活推送通知。看起来就像你需要的只是推送VOIP，你必须激活推送(传统)
