用于 Swift 3 的 Parse Starter 工具包

Question

我已经下载了 ParseStarterProject 版本 1.14.3，下载后它要求我转换为 swift 3。之后给我一个错误：

Cannot convert value of type '(Bool, NSError?) -> ()' to expected argument type 'PFBooleanResultBlock?'

代码：

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)
        }
    } as! PFBooleanResultBlock as! PFBooleanResultBlock as! PFBooleanResultBlock as! PFBooleanResultBlock as! PFBooleanResultBlock as! PFBooleanResultBlock as! PFBooleanResultBlock
}

我尝试用另一个线程解决 (AppDelegate.swift function returning errors after converting to swift 3 (cannot convert to PFBooleanResultBlock?)?)

但是给了我这个错误：

 "Expected ) in the expression list"

我试图重现相同的错误，我只是将 swift3 生成的代码替换为：

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


    PFPush.subscribeToChannel(inBackground: "") { (succeeded, error) 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)
        }
    }

}

func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
    if error._code == 3010 {
        print("Push notifications are not supported in the iOS Simulator.\n")
    } else {
        print("application:didFailToRegisterForRemoteNotificationsWithError: %@\n", error)
    }
}

成功了
