用户按下按钮时如何打开设置应用程序?

How can I open the Settings app when the user presses a button?(用户按下按钮时如何打开设置应用程序?)

问题描述

据我了解，使用这样的代码:

From what I understand by using code like this:

NSURL* appUrl = [NSURL URLWithString: @"URL"];
[[UIApplication sharedApplication] openURL:appUrl];

当用户说按下按钮时，我可以打开 Map、YouTube、Safari、Mail、iTunes 和 App Store.

I can open Map, YouTube, Safari, Mail, iTunes and the App Store, when a user say presses a button.

但我想知道是否可以使用这种方法打开设置应用程序.

But I was wondering is it possible to open the Settings app with this method.

基本上，当用户第一次打开我的应用程序时，我希望弹出一个 UIAlertView，让用户知道他们可以根据需要更改特定设置，然后他们按 OK 或按设置将他们带到设置应用程序.

Basically, the first time the user opens my app I want a UIAlertView to pop up to let the user know that they can change a specific setting if they want, and either they press OK or they press settings to take them to the settings app.

我知道 Apple 在某些情况下会这样做，但开发人员可以这样做吗?

I know that Apple do that in some situations, but is it possible for developers to do that?
