//转换字符串
CFStringRef aCFString = (__bridge CFStringRef)@"魑魅魍魉";
//copy 一下，另外改为可变的
CFMutableStringRef string = CFStringCreateMutableCopy(NULL, 0, aCFString);
//翻译一下，改为拼音（带音调的）：shí jiā zhuāng shì
CFStringTransform(string, NULL, kCFStringTransformMandarinLatin, NO);
//去声调！！！：shi jia zhuang shi
CFStringTransform(string, NULL, kCFStringTransformStripDiacritics, NO);

//转化为oc：NSString
NSString *pinYinName = (__bridge NSString *)string;
CFRelease(string);
NSLog(@"%@",pinYinName);
