Just wondering if it\'s possible to add a button like the \"Clear History\", \"Clear Cookies\" etc buttons in the Safari preferences to your own app\'s settings bundle? Bee
No, this is not possible. The system only supports interacting with the values from within your app. You can't run code from the settings app so a button would be useless.
iOSOpenDev, which extends Xcode for iOS jailbreak-style project development, provides project templates that have a check boxes to include either a simple PreferenceLoader (plist-based) or a full PreferenceLoader bundle.
Nike+iPod is a root application. Anything running under root can run code from basically anywhere (with restrictions, Sandbox is a b**ch) If you're interested you can make a jailbreak preferencebundle with Theos or iOSOpenDev! Which allows you to make a root bundle that can run button action code.
