An approach I've used before is to create a file Settings.plist and load it into NSUserDefaults upon launch using registerDefaults:. You can then access its contents with the following:

// Assuming you've defined some constant kMySettingKey.
[[NSUserDefaults standardUserDefaults] objectForKey:kMySettingKey];

While I haven't done any Android development, it sounds as though this is analogous to the strings resource file you described. The only downside is that you can't use the preprocessor to swap between settings (e.g. in DEBUG mode). I suppose you could load in a different file, though.
