【iOS开发】字符串汉字转拼音

汉字转拼音方法：

// 汉字转拼音
- (NSString *)transformChineseToPinyin:(NSString *)chinese{
    //将NSString装换成NSMutableString
    NSMutableString *pinyin = [chinese mutableCopy];

    //将汉字转换为拼音(带音标)
    CFStringTransform((__bridge CFMutableStringRef)pinyin, NULL, kCFStringTransformMandarinLatin, NO);

    //去掉拼音的音标
    CFStringTransform((__bridge CFMutableStringRef)pinyin, NULL, kCFStringTransformStripCombiningMarks, NO);

    //返回最近结果
    return pinyin;

}

完整代码：

- (void)viewDidLoad
{
    [super viewDidLoad];

    NSString *string_before = @"江一燕";
    NSString *string_after = @"";
    string_after = [self transformChineseToPinyin:string_before];

    NSLog(@"转换前-----%@    转换后-----%@",string_before,string_after);
}

// 汉字转拼音
- (NSString *)transformChineseToPinyin:(NSString *)chinese{
    //将NSString装换成NSMutableString
    NSMutableString *pinyin = [chinese mutableCopy];

    //将汉字转换为拼音(带音标)
    CFStringTransform((__bridge CFMutableStringRef)pinyin, NULL, kCFStringTransformMandarinLatin, NO);

    //去掉拼音的音标
    CFStringTransform((__bridge CFMutableStringRef)pinyin, NULL, kCFStringTransformStripCombiningMarks, NO);

    //返回最近结果
    return pinyin;

}
