我使用此应用的测试

https://itunes.apple.com/us/app/easy-apns-provider-push-notification/id989622350?mt=12

这是我的代码在我的AppDelegate

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

    registerForPushNotifications(application) 

    print(UIDevice.currentDevice().identifierForVendor!.UUIDString) 

    return true 
} 


func registerForPushNotifications(application: UIApplication) { 
    let notificationSettings = UIUserNotificationSettings(
     forTypes: [.Badge, .Sound, .Alert], categories: nil) 
    application.registerUserNotificationSettings(notificationSettings) 
} 

func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) { 
    if notificationSettings.types != .None { 
     application.registerForRemoteNotifications() 
    } 
} 

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) { 
    let tokenChars = UnsafePointer<CChar>(deviceToken.bytes) 
    var tokenString = "" 

    for i in 0..<deviceToken.length { 
     tokenString += String(format: "%02.2hhx", arguments: [tokenChars[i]]) 
    } 

    print("Device Token:", tokenString) 
} 

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