使用到的三方库

cocoapods导入  

pod 'libxlsxwriter', '~> 0.8.3'

 

1.引入头文件

#import <xlsxwriter/xlsxwriter.h>

 

2.示例代码

    NSArray *array=@[@{@"name":@"数学",@"time":@"2018-10-21"},@{@"name":@"语文",@"time":@"2018-10-22"}];

    

    // 文件保存的路径

    NSString *documentPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES) objectAtIndex:0];

    NSString *filename = [documentPath stringByAppendingPathComponent:@"testDemo.xlsx"];

    NSLog(@"filepath:%@",filename);

    

    lxw_workbook  *workbook  = workbook_new([filename UTF8String]);// 创建新xlsx文件，路径需要转成c字符串

    lxw_worksheet *worksheet = workbook_add_worksheet(workbook, NULL);// 创建sheet

    

 

    [array enumerateObjectsUsingBlock:^(id  _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {

        NSDictionary *aDic=obj;

        NSString *name=aDic[@"name"];

        NSString *time=aDic[@"time"];

 

        uint32_t lxw_row_t = (uint32_t)idx;

        

        worksheet_write_string(worksheet, lxw_row_t, 0, [name UTF8String], NULL);

        worksheet_write_string(worksheet, lxw_row_t, 1, [time UTF8String], NULL);

 

    }];

    

    //关闭，保存文件

    workbook_close(workbook);

 

3.最终结果 （生成的excel文件在filepath打印的文件路径中，finder前往文件夹即可）
