Just wondering if you can add a button similar to the buttons "Clear History", "Clear Cookies", etc. in Safari settings, in your own set of application settings? Breaking through dev docs and can't find any plist specifier for the button, so I'm wondering if this is an internal API for Apple guys?
After you click the button, you will get an action sheet asking if you really want to do this, and then there seems to be some feedback based on user input.
They also noticed that there is a clear button in the Nike + iPod settings, but again, this application can have access to internal APIs that we donβt have.
