我正在尝试在Excel中集成excel电子表格，以便最终可以通过.xls或.csv格式的电子邮件发送。我找到了一个教程，我认为这是我正在寻找但我不知道如何在电子邮件中发送它。我熟悉在电子邮件中发送文本，但现在发送文件非常多。
这是教程的链接 - http://xcodetipss.blogspot.com/2013/11/create-excelxls-file-programatically-in.html
这是教程代码：
1. Download Library from the url : Libxl Download and then add LibXL.framework to your xcode project
2. Down your deployment target to ios6.0
3. In Other linker Flag - set "-lstdc++"
4. Add Framework - “libc++.dylib”
5. Add in your view controller -
#include "LibXL/libxl.h”
6. Create xls file from the below code and save to document directory.
BookHandle book = xlCreateBook(); // use xlCreateXMLBook() for working with xlsx files SheetHandle sheet = xlBookAddSheet(book, "Sheet1", NULL);
FontHandle font = xlBookAddFont(book, 0);
xlFontSetColor(font, COLOR_RED);
xlFontSetBold(font, true);
FormatHandle boldFormat = xlBookAddFormat(book, 0);
xlFormatSetFont(boldFormat, font);
xlSheetWriteStr(sheet, 2, 1, "Title", boldFormat);
xlSheetWriteStr(sheet, 2, 2, "First name", boldFormat);
xlSheetWriteStr(sheet, 2, 3, "Last name", boldFormat);
xlSheetWriteStr(sheet, 2, 4, "Nationality", boldFormat);
xlSheetWriteStr(sheet, 2, 5, "Address", boldFormat);
xlSheetWriteStr(sheet, 2, 6, "P.O.Box", boldFormat);
xlSheetWriteStr(sheet, 2, 7, "City", boldFormat);
xlSheetWriteStr(sheet, 2, 8, "Country", boldFormat);
xlSheetWriteStr(sheet, 2, 9, "Phone", boldFormat);
xlSheetWriteStr(sheet, 2, 10, "Email", boldFormat);
xlSheetWriteStr(sheet, 2, 11, "Birth Date", boldFormat);
xlSheetWriteStr(sheet, 2, 12, "Wedding Date", boldFormat);
NSMutableArray *dataArray = [[NSMutableArray alloc]init];
dataArray = [Database executeQuery:@"select * from user"];
for (int i=0; i<[dataArray count]; i++) {
NSDictionary *dict = [dataArray objectAtIndex:i];
const char *converted_back = [[dict objectForKey:@"title"] UTF8String];
const char *converted_back1 = [[dict objectForKey:@"firstname"] UTF8String];
const char *converted_back2 = [[dict objectForKey:@"lastname"] UTF8String];
const char *converted_back3 = [[dict objectForKey:@"nationality"] UTF8String];
const char *converted_back4 = [[dict objectForKey:@"address"] UTF8String];
const char *converted_back5 = [[dict objectForKey:@"pobox"] UTF8String];
const char *converted_back6 = [[dict objectForKey:@"city"] UTF8String];
const char *converted_back7 = [[dict objectForKey:@"country"] UTF8String];
const char *converted_back8 = [[dict objectForKey:@"phone"] UTF8String];
const char *converted_back9 = [[dict objectForKey:@"email"] UTF8String];
const char *converted_back10 = [[dict objectForKey:@"birthdate"] UTF8String];
const char *converted_back11 = [[dict objectForKey:@"weddingdate"] UTF8String];
xlSheetWriteStr(sheet, i+3, 1, converted_back, 0);
xlSheetWriteStr(sheet, i+3, 2, converted_back1, 0);
xlSheetWriteStr(sheet, i+3, 3, converted_back2, 0);
xlSheetWriteStr(sheet, i+3, 4, converted_back3, 0);
xlSheetWriteStr(sheet, i+3, 5, converted_back4, 0);
xlSheetWriteStr(sheet, i+3, 6, converted_back5, 0);
xlSheetWriteStr(sheet, i+3, 7, converted_back6, 0);
xlSheetWriteStr(sheet, i+3, 8, converted_back7, 0);
xlSheetWriteStr(sheet, i+3, 9, converted_back8, 0);
xlSheetWriteStr(sheet, i+3, 10, converted_back9, 0);
xlSheetWriteStr(sheet, i+3, 11, converted_back10, 0);
xlSheetWriteStr(sheet, i+3, 12, converted_back11, 0);
}
NSString *documentPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES) objectAtIndex:0];
NSString *filename = [documentPath stringByAppendingPathComponent:@"Cartier.xls"]; xlBookSave(book, [filename UTF8String]);
xlBookRelease(book);
所以我的问题是 - 我如何在xcode中实现它，以便它可以通过电子邮件发送。
提前致谢。

一旦将其保存到文档目录中，通过电子邮件发送它就非常简单：
if (![MFMailComposeViewController canSendMail]) {
//Show alert that device cannot send email, this is because an email account hasn't been setup.
}
else {
//**EDIT HERE**
//Use this to retrieve your recently saved file
NSString *documentPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES) objectAtIndex:0];
NSString *filename = [documentPath stringByAppendingPathComponent:@"Cartier.xls"];
//**END OF EDIT**
NSString *mimeType = @"application/vnd.ms-excel"; //This should be the MIME type for els files. May want to double check.
NSData *fileData = [NSData dataWithContentsOfFile:fileName];
NSString *fileNameWithExtension = @"Cartier.xls"; //This is what you want the file to be called on the email along with it's extension:
//If you want to then delete the file:
NSError *error;
if (![[NSFileManager defaultManager] removeItemAtPath:fileName error:&error])
NSLog(@"ERROR REMOVING FILE: %@", [error localizedDescription]);
//Send email
MFMailComposeViewController *mailMessage = [[MFMailComposeViewController alloc] init];
[mailMessage setMailComposeDelegate:self];
[mailMessage addAttachmentData:fileData mimeType:mimeType fileName:fileNameWithExtension];
[self presentViewController:mailMessage animated:YES completion:nil];
}
电子邮件委托方法是：
- (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error {
switch (result)
{
case MFMailComposeResultCancelled:
NSLog(@"Mail cancelled: you cancelled the operation and no email message was queued.");
break;
case MFMailComposeResultSaved:
NSLog(@"Mail saved: you saved the email message in the drafts folder.");
break;
case MFMailComposeResultSent:
NSLog(@"Mail send: the email message is queued in the outbox. It is ready to send.");
break;
case MFMailComposeResultFailed:
NSLog(@"Mail failed: the email message was not saved or queued, possibly due to an error.");
break;
default:
NSLog(@"Mail not sent.");
break;
}
[controller dismissViewControllerAnimated:YES completion:nil];
}

您需要包含MessageUI框架（Build Phases，Link Binary with Libraries），然后在顶部的.h中添加：
#import <MessageUI/MessageUI.h>
然后订阅代表：
@interface YOURCONTROLLER : UIViewController <MFMailComposeViewControllerDelegate>
＃用于以编程方式创建Excel电子表格
NSMutableString *stringToWrite = [[NSMutableString alloc] init];
[stringToWrite appendString:[NSString stringWithFormat:@"First Name /t Last Name /t Full Name /t Phone Number /t Email /t Job /t organizationName /t Note\n\n"]];
