为什么iPhone模拟器3.0没有出现在Xcode中？

Question

I have installed the new 3.0 SDK, but when I start up Xcode, I don't see an option to build for "Device - iPhone OS 3.0" or "Simulator - iPhone OS 3.0"

The Xcode About box says I am running: 3.1.2

Is there something else I have to do?

Answer 1

I think you need to upgrade to Xcode 3.1.3. I have the latest version and that's what my About box reads.

If you are sure you downloaded the latest version, perhaps you installed in to a different location?

Answer 2

If you are using an existing project you may have to tell your project to build to the 3.0 targets. I didn't have to do this for any of my projects but ...

Under the Deployment section of your project properties you should see:

iPhone OS Deployment Target - (change this to use iPhone OS 3.0)

You can also check that the Architectures section has the Base SDK set to 3.0.

Answer 3

This is what worked for me:

I clicked on the box (where I expected iPhone Simulator to be shown), right clicked manage scheme. After that deleted all schemes, and in similar way, created a new scheme. It automatically produced all simulators including the ones for devices.

Answer 4

This happens quite often when downloading Apple's sample code projects which are targeted for iOS 3.x but you've got iOS 4.x.

To show Simulator option go to Project Info window -> General tab -> Base SDK for All Configurations - choose Latest iOS.

If it doesn't appear straight away, close and reopen Xcode.
