I'm working on an universal iOS app, but a few user settings don't make as much sense on the iPad. Can I specify a separate Settings.bundle or Root.plist for use on the iPad? from 4.0 on you will be able to just rename the file for ipad to contain ~ipad in name and ~iphoone for the iphone ones, for now you can only rename the iphone one and have 3.2 on ipad load the regular named ones. 来源： https://stackoverflow.com/questions/3277034/separate-settings-in-universal-ios-app
