尝试将设备注册到 Bluemix 上的 IBM Mobile First Push 服务时，iOS 应用程序崩溃

Question

我有一个在 iPad mini 4 (iOS 9.0.2) 上运行的 iOS 9 应用程序。尝试将设备注册到我在 Bluemix 上的 IMFPush 服务实例时崩溃。

这是在我的 App delegate 中执行注册的代码:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Push notifications
    let notificationTypes: UIUserNotificationType = [UIUserNotificationType.Badge, UIUserNotificationType.Alert, UIUserNotificationType.Sound]
    let notificationSettings: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: nil)
    application.registerUserNotificationSettings(notificationSettings)
    application.registerForRemoteNotifications()
    return true
}

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    // Initialize the Mobile First SDK with IBM Bluemix GUID and route
    IMFClient.sharedInstance().initializeWithBackendRoute(MY_APP_ROUTE_HERE, backendGUID: MY_BACKEND_GUID_HERE)
    let push = IMFPushClient.sharedInstance()
    print("-> Register device token to Mobile First Push for iOS8 Service \(IMFPush.version())");
    push.registerDeviceToken(deviceToken, completionHandler: { (response, error) -> Void in
        if error != nil {
            print("-> Error during device registration to Mobile First Push for iOS8 Service \(error.description)")
        }
        else {
            print("-> Response after device registration (json): \(response.responseJson.description)")
        }
    })
}

这是运行应用程序时的控制台输出(启动时崩溃):

确保您的客户端应用程序是使用 -Objcflags编译的。

此设置可以添加到目标的Build Settings>Linking>Other Linker Flags 部分下。

双击现有设置并单击+ 符号。然后在文本字段中添加“-ObjC”。这可以针对调试和发布设置来完成。
