Downloading xcode 4 - will i be able to stick with iOS4.2 simulator?

Question

I want my iOS simulator to stay at 4.2, but i do want to upgrade to XCode 4 also. Would i be able to upgrade to XCode 4 and stay at iOS4.2?

Answer 1

XCode 4提供了多个版本的模拟器进行测试。您可以为iPhone模拟器选择4.1,4.2或4.3，为iPad选择4.2或4.3。

Answer 2

I don't understand why you want your sim to stay at 4.2. It doesn't offer you anything. If you think you can use it for compatibility testing, you'd be sorely mistaken. Many things don't work right in the sim, and certainly behaviours are different in some cases. It is no suitable substitute for having a device with a particular firmware version on (the lowest you want to support at a minimum).

Short answer: No it will upgrade your sim. But no, that shouldn't ever be a problem.
