iOS、Mac OS X系统中编程实现汉字转拼音的方法（超级简单）

        NSMutableString *ms = [[NSMutableString alloc] initWithString:@"我是中国人"];
        if (CFStringTransform((__bridge CFMutableStringRef)ms, 0, kCFStringTransformMandarinLatin, NO)) {
            NSLog(@"Pingying: %@", ms); // wǒ shì zhōng guó rén
        }
        if (CFStringTransform((__bridge CFMutableStringRef)ms, 0, kCFStringTransformStripDiacritics, NO)) {
            NSLog(@"Pingying: %@", ms); // wo shi zhong guo ren
        }
