swift 2:没有委托回调推送通知而不是objective-c

Question

我创建了2个示例(单视图)项目来测试推送通知,除了通知设置代码之外,我没有添加任何代码,如下所示:

Project1(Swift 2):

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
    UIApplication.sharedApplication().registerUserNotificationSettings(settings)
    UIApplication.sharedApplication().registerForRemoteNotifications()

    return true
}

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

    print("didRegisterUserNotificationSettings got called")

}

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

    let trimmedDeviceToken = deviceToken.description .stringByTrimmingCharactersInSet(NSCharacterSet(charactersInString: "<>"))
        .stringByReplacingOccurrencesOfString(" ", withString: "")
    print("Device Token \(trimmedDeviceToken)")

}

func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
    print("Failed to get token, error: \(error)")
}

Project2(Objective-C):

 -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

UIUserNotificationSettings* notificationSettings =
[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert|UIUserNotificationTypeBadge) categories:nil];

[application registerUserNotificationSettings:notificationSettings];
[application registerForRemoteNotifications];

return YES;
}

  -(void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {

NSLog(@"didRegisterUserNotificationSettings got called");

}

  -(void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
 {

NSString* newToken = [deviceToken description];
newToken = [newToken stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];
newToken = [newToken stringByReplacingOccurrencesOfString:@" " withString:@""];

NSLog(@"Device Token %@", newToken);
 }

   -(void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error
 {
         NSLog(@"Failed to get token, error: %@", error);
 }

objective-c项目在所有经过测试的设备上运行正常:注册自己进行远程通知并在委托回调方法中接收设备令牌,但swift项目无法获得任何委托回调.

在将此问题标记为重复之前阅读我尝试过的内容:

1)AppID是推送通知
2)推送证书类型是生产,供应配置文件是AdHoc生产
3)两个项目使用相同的AppID,推送证书和配置文件
4)两个项目都已在3个不同的iPhone上测试(5,6& 6Plus)全部运行iOS 9.2,每次安装都删除了应用程序,并多次重启所有这些
5)在2台不同的MAC Pro机器上使用Xcode 7.2构建了两个项目
6)所有3台iPhone都使用没有防火墙的互联网连接,所有端口都打开(如本技术说明中所述),还将3台设备上的互联网连接改为3G连接,而不是WIFI.
7)选中/取消选中项目设置中的推送通知 - >两个项目的功能(顺便说一句,这点在我测试时没有效果)
8)尝试了Xcode Run(顶部按钮)和两个项目的Export ipa包
9)尝试使用方法registerForRemoteNotifications(
)尝试另一个全新的AppID,推送证书和两个项目的配置文件,同时尝试(application)和([UIApplication sharedApplication] for objective-c和UIApplication.sharedApplication()).
11)删除了两个项目,并使用与上面相同的代码创建了另外两个新项目

所有这些尝试之后的objective-c项目工作正常,并通过didRegisterForRemoteNotificationsWithDeviceToken方法接收设备令牌,但快速的方法不起作用.

我已经使用PersistentConnectionLogging.mobileconfigApple的配置文件从iPhone 6Plus设备生成了3个APN日志文件,并在此处上传,(在apsd_2016_02_24_11_36_29+0300.log文件中,Objective-c项目BundleID是XXXXX.push.notification,swift项目BundleID是XXXXX.apnsswift)

事实证明，这个奇怪问题背后的原因是 swift 的print方法没有在设备日志中显示输出NSLog，而 swift 应用程序没有问题，它只需要用来NSLog在推送通知委托回调方法中显示消息。

//print("Device Token \(trimmedDeviceToken)")
NSLog("Device Token: %@",trimmedDeviceToken)
