分解不用正则表达式,而用for循环折腾你就out了.block遍历以及forin方式都是设计模式中的迭代器模式,效率要比for循环高哦.

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:@"\n"];        //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);                               }];    }];
