解析推送通知 - Swift安装不起作用

Question

我试图在我的应用程序(所有swift)上运行Parse推送通知,但在尝试实现时,我收到错误 'PFInstallation' does not have a member named 'saveInBackground'

这是我的代码.

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

    Parse.setApplicationId("APP ID HIDDEN", clientKey: "CLIENT ID HIDDEN")

   // let notificationTypes:UIUserNotificationType = UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound
    //let notificationSettings:UIUserNotificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: nil)
    var notificationType: UIUserNotificationType = UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound

    var settings: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: notificationType, categories: nil)
    UIApplication.sharedApplication().registerUserNotificationSettings(settings)
    UIApplication.sharedApplication().registerForRemoteNotifications()

    //UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings)
    // Override point for customization after application launch.
    return true
}

func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings!) {
   UIApplication.sharedApplication().registerForRemoteNotifications()

}

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

    var currentInstallation: PFInstallation = PFInstallation()
    currentInstallation.setDeviceTokenFromData(deviceToken)
    currentInstallation.saveInBackground()

    println("got device id! \(deviceToken)")

}


func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
    println(error.localizedDescription)
    println("could not register: \(error)")
}

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
    PFPush.handlePush(userInfo)
}

当我更改currentInstallation.saveInBackground为currentInstallation.saveEvenutally(),代码编译正常..

但在尝试成功注册推送通知时,控制台中会弹出一个错误消息 Error: deviceType must be specified in this operation (Code: 135, Version: 1.4.2)

我花了好几个小时试图解决这个问题,没有骰子,任何帮助都是值得欣赏的.

对于出现此错误的任何其他人,请确保将Bolts框架导入到桥接头文件中

在他们的废话文档中没有概述.

这解决了这个问题.

下面是代码.

#import <Parse/Parse.h>
#import <Bolts/Bolts.h>

只需将其添加到您的桥接标题即可.谢谢

有效的PFInstallation只能通过[PFInstallation currentInstallation]实例化,因为所需的标识符字段是只读的.(来源)

所以代替:

var currentInstallation: PFInstallation = PFInstallation()

尝试:

var currentInstallation = PFInstallation.currentInstallation()
