You must either detect the device and iOS limitations prior to using this controller, or risk restricting your app to recently upgraded 3G, 3GS, and 4 iPhones. Keep in mind that this won't work on phones without iOS 4, and it won't work on the iPod touch or the iPad, except, perhaps, under iOS 5.

You can edit the subject and add attachments to the message, where the medium allows it. You can now check to see if the message medium you are using will accept a subject or attachments, and what kind of attachments it will accept. If this is the case, then Apple is running an SMS server that sends messages on behalf of devices that don't have a cellular modem. IOS 5 includes messaging for iPod touch and iPad devices, so while I've not yet tested this myself, it may be that all iOS devices will be able to send SMS via MFMessageComposeViewController. The MFMessageComposeViewController class is well documented, and tutorials show how easy it is to implement. But this at least allows you to populate everything, and avoids closing the application. You still cannot send fully automated SMS from the iPhone itself, it requires some user interaction. This prevents applications from sending automated SMS without the user explicitly aware of it.
You can even specify multiple recipients. Unlike using the "SMS." url format, this allows your application to stay open, and allows you to populate both the to and the body fields. You prepopulate the SMS fields, then the user can initiate the SMS send within the controller. IOS 4, however, now provides a viewController you can import into your application.

(ie, your program on the iPhone sends a UDP packet to your server, which sends the real SMS) iOS 4 Update Your best bet is to set up an intermediate server on the internet that uses an online SMS sending service and send the SMS via that route if you need complete automation. (Imagine if the game instead dialed 911 at a particular time of day) I'm sure you really want to have spams from your friends, "Try out this new game! It roxxers my boxxers, and yours will be too! !!!! If you sign up now you'll get 3,200 RB points!!"Īpple has restrictions for automated (or even partially automated) SMS and dialing operations. If you could send an SMS within a program on the iPhone, you'll be able to write games that spam people in the background.
