iPhone: How to Programmatically Respond to SMS Messages

Question

Answer 1

BREW and J2ME had (and probably still have) ways to launch your app via specially formatted SMS, which may be what the Jeff is referring to.

Apple does have the upcoming Push Server which will allow you to send the user an alert which will give them the option of launching your app, but you cannot launch your app for them.

Answer 2

Unfortunately, you cannot intercept - or be notified of - incoming SMS messages with the iPhone SDK.

One possible alternative, is to register a custom URL scheme that launches your application when a url with that scheme is embedded in the sms message and the user cicks on it.

to set a custom url scheme, you must implement both the CFBundleURLSchemes and CFBundleURLName keys in your application's info.plist.

In your Application's delegate, you can then implement the application:handleOpenURL: method to get any paramaters that were passed to your App from the url in the SMS message.

You can use CoreTelephony framework.But you must user some private api.And I have some demo code for this. https://github.com/edison0951/AppNotifyBySMSDemo

Answer 4

Unfortunately just registering an URL scheme dosn't help you at all, because the SMS app makes "http://" urls clickable only...

I believe that currently the SDK doesn't allow for background apps (except for apple ones).
