programmatically READ iPhone settings

I want to programmatically READ iPhone settings such as...

• Enable 3G - YES/NO
• Vibrate - ON/OFF
• Message Alert - 开发者_开发问答ON/OFF
• etc.

Can anyone provide a solution?

I'm fairly certain you cannot: see Opening the Settings app from another app

You cannot. Because apple is not providing the API to access the iPhone settings app. But you can keep a bundle setting in your app so that user can change the settings of your app from iphone settings. If you are interested in this feature you can refer Apple doc.
