sending attachments to email from iphone app

moonraker928 · 01-10-2009, 06:27 PM

is there a way to add attachments (esp, images)? I know there wasn't before, but do the current Mail APIs support this feature?

RickMaddy · 01-10-2009, 06:47 PM

The SDK does not allow email attachments as of SDK 2.2. I wish it did.

I send emails with attachments from my app. For that I use the SKSMTP and libz/minizip packages.

Could you give some more details? I'd love to know how as well.

skpsmtpmessage - Google Code

Look at thread 7615 for the zipping. I can't paste the link here because the jesusfone is too stupid for a simple cut-n-paste.

By the way, in playing around with sksmtp I found a bug if you use it with TLS authentication to a mail server that is using self-signed certificates. The code attempts to handle this by setting the relevant stream property (kCFStreamSSLValidatesCertificateChain); however, it seems that this property is ignored unless it is called AFTER setting the stream security level to TLSv1.

There are a lot of issues with it. I found a couple myself. It is a great start though.

In the sample code for the skpsmtp, I'm having trouble following the attachment process:

What do I change the content type to if I want to attach an image or anything besides texzt
Right now its

Code:

text/directory/\r\n\t-unix-mode=0644;\r\n\t\name=\"anImage.png\"", kSKPSMTPPartContentTypeKey, ...

smithdale87, are you getting skpsmpt to work on your app with sending plain text emails??

**smithdale87** · 01-14-2009, 10:30 AM

yup

**smithdale87** · 01-14-2009, 10:37 AM

Alright got it working!

Here's what I needed to know about the content-type, which you need to change depending on what filetype you're sending:

Quote:

image, audio, video and application (for example, image/jpg, audio/mp3, video/mp4, and application/msword and so on)

So if I want to send an png image, I'll change it to

Code:

image/png\r\n\t-unix-mode=0644;\r\n\t\name=\"anImage.png\"", kSKPSMTPPartContentTypeKey, ...

moonraker928 · 01-14-2009, 10:38 AM

so i have included the following files:

Base64Transcoder.h/m
NSData+Base64Additions.h
NSStream+SKPSMTPExtensions.h/m
SKPSMTPMessage.h/m

i have also built the library, libsmtpmessage.a in my app frameworks.

i am getting a duplicate symbol linker error when i build my app. it is in regards to the duplicate building of SKPSMTPMessage and NSStream+SKPSMTPExtensions since it is found both in the library and the individual .h files. however, if i remove the .h files or the library, the app doesn't work.

what i want to know from you is which files you included/did u face any errors during building/how did u fix them?

thanks a bunch!

**smithdale87** · 01-14-2009, 11:08 AM

to begin with, I just ran the project that was included with the download. It all worked fine.

On a side note: I'm now having trouble including html links in the body of my message. Does anyone have a clue how do this?

You only need one of them - either including the whole source into your project, or building and using the library.

for a binary file (aka attachment) you can use "application/octet-stream"

Hi there,
does anyone of you know
how to send sms through our own application.
i tried with some classes of iSms application
but it stuck somewhere in device.c file
where it is trying to open "dev/tty.debug " file
and getting terminated
is there any other way ?(except openURL because we cant send message body). thanks

Don't hijack threads.

On a side note, has anyone been able to successfully get urls in the body of your email message when using sksmtp? When I try, the entire body becomes blank.

moonraker928 · 01-15-2009, 10:54 AM

i built the library and updated the linker flags in the app properties. then i just initialized an SKPSMTPMessage object by saying:

SKPSMTPMessage *test = [[SKPSMTPMessage alloc] init];

but i am getting an error taht this symbol is not defined and can't be foun anywhere. since i dont have the m/h files beacuse I am building the library, how do i resolve this?

**smithdale87** · 01-15-2009, 10:57 AM

you need to include the header files

**smithdale87** · 01-15-2009, 06:44 PM

When I send an email using skpsmtp, the recipient sees the sender as the username of the authentication credentials for the relay server. IIs there anyway to send the mail directly instead of relaying? Or how would I show the correct sender in the relay?

lbendlin · 01-15-2009, 07:23 PM

Do you use

SKPSMTPMessage *trackMsg = [[SKPSMTPMessage alloc] init];
trackMsg.fromEmail = @"me@mydomain.com";
trackMsg.toEmail = email;
trackMsg.login = @"user";
trackMsg.pass = @"password";

?

**smithdale87** · 01-15-2009, 07:58 PM

just answered my own question

Code:

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'send requires relayHost'

**smithdale87** · 01-19-2009, 09:21 PM

Just figured out how to send url links in the body using the skcpsmtp sender.

You have to set the "plainPart" to use "text/html" instead of "text/plain";

Can someone help me as how to use the library to send a jpg image as attachments. I am using the following code to send an email with attachments. The email is sent with an attachment, but when I tried opening it nothing shows up

Code:

NSDictionary *vcfPart = [NSDictionary dictionaryWithObjectsAndKeys:@"image/jpg\r\n\t-unix-mode=0644;\r\n\t\name=\"liberty.jpg\"", kSKPSMTPPartContentTypeKey,
                             @"attachment;\r\n\tfilename=\"liberty.jpg\"",kSKPSMTPPartContentDispositionKey,[vcfData encodeBase64ForData],kSKPSMTPPartMessageKey,@"base64",kSKPSMTPPartContentTransferEncodingKey,nil];

Thanks for any help,
Javid

I don't see anywhere that you are including an NSData object with the image's data
