ios - Restrict iPhone/iPad App to iPhone 4 and higher only? -

I'm looking to create my app so that it works only on iPhone4 or higher, and not 3GS.

How can I do this? Is this architecture done by setting it into Standard Arms 7 / ERM 7

and the valid architecture is named ARM 7 & amp; Armv7s?

Or do I need to see the deployment goal? And set it up in a certain iOS version?

Thanks in advance!

Deployment target is only allowing you to target a specific iOS version and a 3GS iOS 6 Can run. If you are blocking the old device from running your application, then you can do some testing for the device model within AppDelegate and restrict functionality.

This is a warning that your app will not likely be in the app store. What feature (s) are you trying to avail that does not support a 3GS?
