iOS. l r c文件获取内容乱码

l r c文件解析需要通过GBK方式解析

NSData*data = [self getFileData:filePath];

//声明gbk解析方式

    NSStringEncoding gbkEncoding = CFStringConvertEncodingToNSStringEncoding(kCFStringEncodingGB_18030_2000);

    NSString*strlrc =[[NSString alloc]initWithData:data encoding:gbkEncoding];

没有解析过时内容显示乱码
