[英]How to attach multiple files in single mail in iOS
我想以编程方式在iOS的单个邮件中发送多个附件文件。 到目前为止,我已经尝试了以下方法:
// I give the file from array
NSString *str_mail = [readingEmfReading objectAtIndex:0];
// here I can encode the file
NSData *myData = [str_mail dataUsingEncoding:NSUTF8StringEncoding]
//here I can attach the file with extance of .csv
[controller addAttachmentData:myData mimeType:@".cvs" fileName:retriveEmail]
//here I can set the body for mail
[controller setMessageBody:@"file" isHTML:NO];
//here code for sent mail
if (controller) [self presentViewController:controller animated:YES completion:nil];
通过使用此代码,我只能发送一个附件。 我想发送多个文件。 我该如何实现?
您添加许多时间addAttachmentData并添加多文件
尝试以下代码:-添加此行
NSString *str_mail = [readingEmfReading objectAtIndex:0];
// here i can encoded the file
NSData *myData = [str_mail dataUsingEncoding:NSUTF8StringEncoding]
NSData *myData1 = [str_mail dataUsingEncoding:NSUTF8StringEncoding]
//here i can attach the file with extance of .csv
[controller addAttachmentData:myData mimeType:@".cvs" fileName:retriveEmail]
//here i can set the body for mail
// For second file
NSData *myData1 = [str_mail dataUsingEncoding:NSUTF8StringEncoding]
[controller addAttachmentData:myData1 mimeType:@".cvs" fileName:retriveEmail]
[controller setMessageBody:@"file" isHTML:NO];
//here code for sent mail
if (controller) [self presentViewController:controller animated:YES completion:nil];
if([MFMailComposeViewController canSendMail])
{
[mailController setMailComposeDelegate:self];
NSString* message=@"";
NSString *filePath;
for (int i=0; i<filesarray.count; i++)
{
if (i==filesarray.count-1)
{
message=[message stringByAppendingFormat:@"%@ ",[filesarray objectAtIndex:i]];
}
else if (i==filesarray.count-2)
{
message=[message stringByAppendingFormat:@"%@ and ",[filesarray objectAtIndex:i]];
}
else
message=[message stringByAppendingFormat:@"%@, ",[filesarray objectAtIndex:i]];
NSString *datPath =[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
datPath = [datPath stringByAppendingFormat:@"/%@.csv",[filesarray objectAtIndex:i]];
filePath = datPath;
[mailController addAttachmentData:[NSData dataWithContentsOfFile:filePath] mimeType:@"text/csv" fileName:[NSString stringWithFormat:@"%@.csv",[filesarray objectAtIndex:i]]];
}
[mailController setSubject:message];
[mailController setMessageBody:@"" isHTML:NO];
[self presentModalViewController:mailController animated:YES];
}
