Question

我正在关注构建VoIP通知演示的this article和M Penades' answer。我可以使用didRegisterUserNotificationSettings注册通知，并可以从didUpdatePushCredentials获取voip令牌。

但是当我使用休斯顿模拟向我的设备发送通知时，我可以从控制台获取1 push notification sent successfully消息但在设备端没有操作或日志。似乎didReceiveIncomingPushWithPayload从未调用过。

P.S。我正在使用Xcode 7.3，iPhone 6（iOS 9.3）和iPad Mini（iOS 9.3）进行开发。分布式Ad Hoc ipa用于安装。

此处张贴的代码。

import UIKit
import PushKit


@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?
let voipRegistry = PKPushRegistry(queue: dispatch_get_main_queue())


func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.
    //Enable all notification type. VoIP Notifications don't present a UI but we will use this to show local nofications later
    let notificationSettings = UIUserNotificationSettings(forTypes: [UIUserNotificationType.Alert, UIUserNotificationType.Badge, UIUserNotificationType.Sound] , categories: nil)

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

    //output what state the app is in. This will be used to see when the app is started in the background
    NSLog("app launched with state \(application.applicationState.stringValue)")
    return true
}

    func applicationWillTerminate(application: UIApplication) {
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
    //output to see when we terminate the app
    NSLog("app terminated")
}

}

extension AppDelegate {

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

    //register for voip notifications
    NSLog("didRegisterUserNotificationSettings called")
    voipRegistry.desiredPushTypes = Set([PKPushTypeVoIP])
    voipRegistry.delegate = self;
}
}

extension AppDelegate: PKPushRegistryDelegate {


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

    //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!) {

    NSLog("didReceiveIncomingPushWithPayload called")


    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 {
        NSLog("incoming notificaiton from background")

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

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

    else {
        NSLog("incoming notificaiton from frontend")


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


            let alertController = UIAlertController(title: "Title", message: "This is UIAlertController default", preferredStyle: UIAlertControllerStyle.Alert)
            let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel, handler: nil)
            let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil)
            alertController.addAction(cancelAction)
            alertController.addAction(okAction)

            UIApplication.sharedApplication().keyWindow?.rootViewController?.presentViewController(alertController, animated: true, completion: nil)

        })
    }

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

func pushRegistry(registry: PKPushRegistry!, didInvalidatePushTokenForType type: String!) {
    NSLog("didInvalidatePushTokenForType called")
    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"
        }
    }
}
}

有关如何收到此类通知的任何想法吗？

最后我解决了这个问题。对于快速源代码是可以的，问题是我错误地将推送请求发送到苹果公司的开发服务器gateway.sandbox.push.apple.com，实际上我们应该向苹果公司的生产服务器gateway.push.apple.com发送请求

如果您关注M Penades' procedure，请注意您需要修改Simplepush脚本，只需在第20行将ssl://gateway.sandbox.push.apple.com:2195替换为ssl://gateway.push.apple.com:2195，然后重试。

希望它适合你。
