I browsed around and saw that MFMessageComposeViewController doesn’t support MMS, however some suggested using third party vendor to send MMS with photo attachments.
Someone know about a free vendor, or examples on using these mms email gateways on iOS devices with photo attachments?
I know how to send a text message using a the email gateway, but not a photo.
Also, anyone heard about a custom-made controller that uses those email gateways, that i can integrate into my app, in the same way i intrgrate MFMessageComposeViewController?
Unfortunately, there is no way to do this currently. The iPhone has no public API for sending MMS. Only way you can achieve this is to use a providers MMS gateway directly, but this would not work worldwide.
These three other stack overflow questions about MMS had the same conclusion:
How can my app send MMS with a photo?
Attach Local image in MMS in iphone
For the current iphone version, MMS is possible or not?
