iOS: How to Get the Device Current Language Setting?

Question

There are some features within my application that are supposed to be based on the language settings of the device where it\'s running.

I want to get the actual language

Answer 1

To know the current language selected within your localizations use

[[NSBundle mainBundle] preferredLocalizations]

Example:

NSString *language = [[[NSBundle mainBundle] preferredLocalizations] objectAtIndex:0];

To get two letter word

NSString *language = [[[[NSBundle mainBundle] preferredLocalizations] objectAtIndex:0] substringToIndex:2];

Swift:

let language = NSBundle.mainBundle().preferredLocalizations.first as NSString
