compiling iphone 3.1.3 with XCode 3.2.3?

I just downloaded XCode 3.2.3 with iphone sdk 4, but I need to compile my app wit开发者_运维知识库h 3.1.3, but there is no option in the project settings for that (just 4.0 or 3.2). Is there any other possibility for me besides downgrading to XCode 3.2.2??

In the Deployment section of the Build settings, there is an option to set iPhone OS Deployment Target. You can choose 3.1.3 from the list of available OS versions.

Yes, you may choose any iPhone OS Deployment target from the list. But make sure that you are not using any iPhone SDK 4.0 specific methods/properties.

That is the catch, isn't it... is there an easy way to check that we're not doing any iOS4 SDK calls if we cant trap it during a compile?

I found this (see the bottom of the page):

Unfortunately, it requires the following on the first step:

"Locate iPhoneOS3.1.3.sdk and iPhoneSimulator3.1.3.sdk from an iPhone SDK 3 installation"

And, of course I blew away my iPhone SDK 3 installation when I installed the iOS 4 SDK. So I'm kinda stuck.

Is there another alternative?

Thanks!

I strongly recommend you read this. SDKs other than 3.2 and 4.0 are no longer available for App Store submission.
