Swift 3的分析入门工具包

我已经下载了ParseStarterProject版本1.14.3，下载后它要求我转换为swift 3。在这之后，我得到了一个错误：

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

代码：

我试着用另一个线程解决（）

但给了我一个错误：

 "Expected ) in the expression list"

我试图重现相同的错误，我只是用以下代码替换swift3生成的代码：

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)
    }
}

A它起作用了

我的项目是

是7个

的列表！PFBooleanResultBlock

输入错误？你为什么要转换成那个类型？它是Xcode自动转换成swift 3…但即使没有那个打字错误，它也不起作用。看起来你的确切问题已经在这里解决了：可能是重复的我看到了，并尝试过，但它也不起作用。谢谢！！大多数人只是投了反对票，因为他们甚至没有检查斯威夫特是否再次改变，有一个新的问题，你可以解决它。再次感谢你。@RenatoPimpão这是真的！朱利安，这个简单的“错误代码”救了我一天。我已经找到了如何管理可选的everywhere，但没有结果。我不得不忽略一个code=1的值，但是分解这个错误对象看起来很古怪。我无法理解为什么苹果会做出一些简单的事情，比如错误代码这么难。

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)
    }
}
