How to make my app work only on iPhone 3G and higher

Is there a way to limit devices, i.e. iPhone 3G and higher, and not to support the iPhone 2G 开发者_StackOverflowand lower. I can't find an element that is different. I would limit it to iOS 3.1, however I'm pretty sure that iPhone 2G and lower can run iOS 3.1.

There is a similar question about 3GS+. But 3G+? That might be tough. I don't see anything in the UIRequiredDeviceCapabilities that specifies the 3G radio. You could try using another key based on a hardware feature that the 3G has that the iPhone doesn't, but then you risk getting your build rejected by Apple.

Using run-time checks to detect hardware as Sam Ritchie also suggests is also a bad idea since (1) that will most certainly trigger a rejection, and if it doesn't (2) people with older devices will be able to purchase the app, only to find out it won't run, and they will complain, which will cause Apple to pull your app from sale anyway.

The only way to do it without resorting to things that Apple disallows is to target iOS 4.0 or higher. 4.0 does not run on the 1st generation. I realize you want to target iOS 3.1, but you either allow all devices, or target 4.0.

One nice way to do this would be to check out the UIDevice-Extension project on github. It gives you the ability to detect what hardware you're running on.

I suspect that the way to solve this would be to examine your app and figure out what exactly you don't want a user of an earlier phone to be able to access. Once you've narrows down the feature, you can easily check for the existence of that specific feature on the device. To do this, include the UIDeviceRequiredCapabilities key in Info.plist, and take a look at Apple's Build Time Configuration guide for a list of all possible values. You'll find it under the "Declaring the Required Device Capabilities" heading. Good luck!

Add some minimal Location based functionality to your app (so that Apple can't reject it), and then add the "gps" key to your app's UIRequiredDeviceCapabilities.

But consider that the percentage of 2G's users who actually still buy apps appears to currently be microscopic, and not worth bothering over. Just state the lack of support for these devices in your description.

The solution is to require "armv7" in the required device capabilities xml.
