How can I add settings to an app? I've never done this before and I don't know where to begin. I would like to make an app where user would set his/her info (like time interval, gender, ...). Uncle Google gives me results that help users of iOS 5 not developers.
Keywords are: Settings.bundle
and NSUserDefaults
. There is a lot information in Google.
Also, check out this awesome framework: InAppSettingsKit.
Good luck.
