I'm using UILocalizedIndexedCollation to index the cells on a UITableView. The problem is that my app has a language system that is independent from the device. For example, the app language can be Chinese while the device is still in English.
Is there a way to change [UILocalizedIndexedCollation currentCollation] without changing the device settings?
