我有这样一个字符串：
    NSString *string=@"Hi,I’mPeter．I’m__________years old．I’m a student of Grade Four．I have a new__________．__________name is Sam．Sam has a__________．Its name is Coco．Eddie and I are in the__________now．We often__________together after class．";
这个字符串是一道填空题，我需要在这段文字的所有空格上加上文本框，用来填写答案！

我只是打酱油的
