Target OS 2.2 and earlier with recent Xcode?

[Brady]

Silly me, for “safety’s sake”, I uninstalled Xcode before installing the new version (okay, not the newest version, I’m using 3.1.4), and now I can’t target iPhone OS 2.2 and earlier (2.2.1 is the earliest I can build for). I want to target 2.0 as there are still lots of devices out there that haven’t been upgraded. I know I’ve heard talk of a way to add <2.2.1 support back into Xcode, but I can’t seem to find out how.

Any thoughts?

REinstall iPhone SDK, you will see some options to turn on OS 2.0 build.

Thanks, I guess somehow I missed that. I’ll give it a try.

No problem, glad to help.

It looks like you should build with the 3.1 SDK even if you’re targeting an earlier version…

From: http://devdb.agon-online.com/developer/doc/downloads.html

A common misconception amongst iPhone developers (including ourselves until recently) is that the SDK version used, also dictates the minimum iPhone OS version that the application will run on. This is not the case. You are free to choose which iPhone OS version to target regardless of which SDK version your application is built against. You select which iPhone OS version to target by setting the iPhone OS Deployment Target setting in your project configuration. So it is perfectly fine (and in fact recommended by Apple) to build your game using SDK 3.1 and targetting e.g. iPhone OS 2.1. Simply select the 3.1 SDK and set the iPhone OS Deployment Target to iPhone OS 2.1. Notice that you can only see this option when the BaseSDK project setting has been set to iPhone Device x.x (as opposed to the default iPhone Simulator x.x).

Both of these values are set in the build tab of project settings when you have Device chosen as the target in the window button-bar pulldown.

So in that case do I take it we should always select “Device - 3.1 | Release” for distribution (or whatever the latest version is), but then in the build tab of the project settings, we set “iPhone OS Deployment Target” (under the Deployment section) to iPhone OS 2.0?
