with iOS 8 Apple has added this to write japanese word or sentences with phonetic guide, called furigana.

i’ve found some post in stackoverflow and [this post of nshipster](http://nshipster.com/ios8/). it seem simple but how can I use it?

if I write this

```
@import CoreText;

NSString *kanji = @"猫";
NSString *hiragana = @"ねこ";

CFStringRef furigana[kCTRubyPositionCount] =
    {(__bridge CFStringRef)hiragana, NULL, NULL, NULL};

CTRubyAnnotationRef ruby =
    CTRubyAnnotationCreate(kCTRubyAlignmentAuto, kCTRubyOverhangAuto, 0.5, furigana);

```

don’t work.

some post put this code, or other like this, in a subclass of textview. i need to do it? if I want to put this code in a UILable subclass, can I do it?

if i’ve a sentence like ‘私は日本人でわありませんけれども、日本語を勉強していますよ。’ How can i use it to insert the furigana?

私(わたし)は日本人(にほんじん)ではありませんけれども、日本語(にほんご)を勉強(べんきょう)していますよ。in the bracket there is the furigana.
