Detect iOS language [closed]

Question

How to detect the iOS language in iOS?

Answer 1

[[[NSUserDefaults standardUserDefaults] objectForKey:@"AppleLanguages"] objectAtIndex:0]]; // us

This writes into a NSString the current country code so you can detect the current language.

Or use this to get the current language and the region:

NSString *locale = [[NSLocale currentLocale] localeIdentifier]; // en_US
