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 Bluemix 上的 IMFPush 服务实例时，它崩溃了。
以下是在我的应用程序委托中执行注册的代码：
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）：
-> Register device token to Mobile First Push for iOS8 Service 1.0
