I'm working on an iOS 8 note taking app that will be released in the US but also in Asian countries. For the latter I need to change the text direction from the default "left to right" to "right to left". Should I let the user change the settings through a toggle or what is the best practice for such a case?
A toggle might take too much space, and will be unnecessary for people who only uses one language.
Should you have a language selector screen instead? And change the text direction base on what language was chosen?
Another way I can think of is to change it base on user's current keyboard, but I'm not sure if that's technically doable.
