打印信息如下：
使用相关的controller读取歌词的代码如下：
//读取歌词 NSString *str = [NSString stringWithContentsOfFile:BUNDLE_PATH(@"月半小夜曲.lrc") encoding:NSUTF8StringEncoding error:nil]; NSLog(@"%@",str); //将歌词根据换行符分割成数组 NSArray *strArray = [str componentsSeparatedByString:@" "]; //分解歌词 [strArray enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) { //初始化一个可变字符串 __block NSMutableString *tmpStr = [[NSMutableString alloc] initWithString:obj]; //正则表达式匹配出【**:**.**】的位置 [YYRegex string:tmpStr pattern:@"\[..:..\...\]" each:^(NSTextCheckingResult *match, NSRange matchRang) { //获取时间轴 NSString *time = [tmpStr substringWithRange:matchRang]; //获取歌词文本 [tmpStr replaceCharactersInRange:matchRang withString:@""]; //打印相关信息 NSLog(@"%@ -- > %@",time,tmpStr); }]; }];
