Problem I’m currently stuck trying to figure out what iPhone OS Deployment Target setting

Problem

I’m currently stuck trying to figure out what “iPhone OS Deployment Target” setting to use. I do not want to write conditional code right now, so I’d like the lowest version that runs my application fine.

At first I thought it would be 2.0 as I wasn’t using any 3.0 features, but then i realized that AVAudioRecorder is a 3.0 API. I don’t want to be manually checking EVERY function I use in the documentation.

Question

Is there a tool that will check the OS availability of each functions you call in your code to figure out what the Deployment Target should be? That tool could be a good old compiler, but the latest version of the iPhone SDK does not come with the PRE-3.0 SDKs.

    There is a way for checking desired older iOS. For example: I have installed the sdk 4.1 and tested the compiling for the 3.1 target.
