生成Excel.xlsx文件 iOS

使用到的三方库 https://github.com/jmcnamara/libxlsxwriter

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）
