在xcode中以编程方式创buildExcel电子表格
我正在尝试将excel电子表格集成到ios中，以便最终以.xls或.csv格式发送电子邮件。 我find了一个教程，我认为这是即时通讯寻找，但我不知道如何发送电子邮件呢。 我很熟悉发送电子邮件中的文本，但现在发送文件太多了。
这里是教程的链接 – http://xcodetipss.blogspot.com/2013/11/create-excelxls-file-programatically-in.html
这里是教程代码：
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, "POBox", 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中实现这个，所以它可以通过电子邮件发送。
提前致谢。

一旦你将它保存到一个文档目录中，通过电子邮件发送它就相当简单：
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]; }
* 编辑 – *
你需要包含MessageUI框架（Build Phases，Link Binary with Libraries），然后在你的.h的顶部添加：
#import <MessageUI/MessageUI.h>
然后订阅委托人：
@interface YOURCONTROLLER : UIViewController <MFMailComposeViewControllerDelegate>
