title: How do you reset an iPhone App's Keychain?
body: <p>I would like to know if there is a way to reset my app's Keychain. I am wondering whether anything like <code>[NSUserDefaults resetStandardUserDefaults]</code> exists for keychain. Keychain is not reset even after the app is deleted. So far the only way I know is to reset them one by one from the app.</p>
