转换为swift 3后,AppDelegate.swift函数返回错误(无法转换为PFBooleanResultBlock？)？

Question

我最近将我的应用程序从之前版本的swift转换为swift 3.0(并且还获得了最新版本的Xcode),并且在许多其他错误中,我收到了以下一个:

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        let installation = PFInstallation.current()
        installation.setDeviceTokenFrom(deviceToken)
        installation.saveInBackground()

        PFPush.subscribeToChannel(inBackground: "") { (succeeded: Bool, error: NSError?) in
            if succeeded {
                print("ParseStarterProject successfully subscribed to push notifications on the broadcast channel.\n");
            } else {
                print("ParseStarterProject failed to subscribe to push notifications on the broadcast channel with error = %@.\n", error)
            }
        }
    }

这来自我作为模板下载的SDK(PF指的是Parse框架......我使用的是Heroku托管的Parse服务器).返回错误说:"无法将类型的值'(Bool,NSError？) - >()'转换为预期的参数类型'PFBooleanResultBlock？'"

不知道如何解决这个问题.有人有什么想法吗？

我相信你可以改变你的代码:

    PFPush.subscribeToChannel(inBackground: "", block: {(succeeded, error) -> Void in
        if succeeded {
            print("ParseStarterProject successfully subscribed to push notifications on the broadcast channel.\n");
        } else {
            print("ParseStarterProject failed to subscribe to push notifications on the broadcast channel with error = %@.\n", error)
        }
    }
