Transliterate/transpose the characters in the NSString

ios, iphone, nsstring, objective-c, transliteration

Solution

Either try `CFStringTransform` function of CFMutableString with `kCFStringTransformToLatin` transform identifier or make a NSString category with simple mapping.

Edited by the question poster: more specifically it should be:

NSMutableString *buffer = [@"русский язык" mutableCopy];
CFMutableStringRef bufferRef = (__bridge CFMutableStringRef)buffer;
CFStringTransform(bufferRef, NULL, kCFStringTransformToLatin, false);
NSLog(@"%@", buffer); // outputs "russkij âzyk"

Problem

I want to transliterate a cyrillic string to it's closest latin equivalent. E.g. "матрешка" => "matreshka", "водка" => "vodka". So ideally I want some ready to use method on the NSString or somewhere else that already knows everything about the alphabets and can do the conversation. But if such functionality doesn't exist in the iOS APIs then I will be totally happy with something like ruby's tr method that just replaces the characters in a string using a simple mapping specified as a parameter. ``` "баба".tr('абвгд', 'abvgd') ```
