最近做一个项目，需要把时延以表格的形式输出，方便后续的数据可视化。

-(void)xlsData{
    
    
    NSUserDefaults *userDef = [NSUserDefaults standardUserDefaults];
    NSMutableArray  *xlsDataMuArr = [[NSMutableArray alloc] init];
    [xlsDataMuArr addObject:@" "];
    [xlsDataMuArr addObject:@" "];
    [xlsDataMuArr addObject:@" "];
    [xlsDataMuArr addObject:@" "];
    [xlsDataMuArr addObject:@" "];
    [xlsDataMuArr addObject:@" "];
    [xlsDataMuArr addObject:@" "];
    [xlsDataMuArr addObject:@" "];
    [xlsDataMuArr addObject:@" "];
    [xlsDataMuArr addObject:@" "];
    [xlsDataMuArr addObject:@" "];
    [xlsDataMuArr addObject:@" "];
    [xlsDataMuArr addObject:@" "];
    [xlsDataMuArr addObject:@" "];
    [xlsDataMuArr addObject:@" "];
    [xlsDataMuArr addObject:@" "];
    for (int i = 1; i < 100; i++) {
    
    
   
        [xlsDataMuArr addObject:@"0"];
        [xlsDataMuArr addObject:@"1"];
        [xlsDataMuArr addObject:@" "];
        [xlsDataMuArr addObject:@" "];
        [xlsDataMuArr addObject:@" "];
        [xlsDataMuArr addObject:@" "];
        [xlsDataMuArr addObject:@" "];
        [xlsDataMuArr addObject:@" "];
        [xlsDataMuArr addObject:@" "];
        [xlsDataMuArr addObject:@" "];
        [xlsDataMuArr addObject:@" "];
        [xlsDataMuArr addObject:@" "];
        [xlsDataMuArr addObject:@" "];
        [xlsDataMuArr addObject:@" "];
        [xlsDataMuArr addObject:@" "];
        [xlsDataMuArr addObject:@" "];
        
        
    }
    NSString *fileContent = [xlsDataMuArr componentsJoinedByString:@"\t"];
    NSMutableString *muStr = [fileContent mutableCopy];
    NSMutableArray *subMuArr = [NSMutableArray array];
    for (int i = 0; i < muStr.length; i ++) {
    
    
        NSRange range = [muStr rangeOfString:@"\t" options:NSBackwardsSearch range:NSMakeRange(i, 1)];
        if (range.length == 1) {
    
    
            [subMuArr addObject:@(range.location)];
        }
    }
    for (NSUInteger i = 0; i < subMuArr.count; i ++) {
    
    
        if ( i > 0 && (i%16 == 0) ) {
    
    
            [muStr replaceCharactersInRange:NSMakeRange([[subMuArr objectAtIndex:i-1] intValue], 1) withString:@"\n"];
        }
    }
    NSFileManager *fileManager = [[NSFileManager alloc]init];
    NSData *fileData = [muStr dataUsingEncoding:NSUTF16StringEncoding];
  //  NSString *path = NSHomeDirectory();
    NSString *filePath = @"/Users/zags k/Desktop/exportVideo.xls";
    NSLog(@"文件路径：\n%@",filePath);
    [fileManager createFileAtPath:filePath contents:fileData attributes:nil];
  
}

这个代码太好用了，直接粘贴就可以，内容自己填！再也不用手动输入数据了。
