问题
I have xcode 4.2.1. The simulator works perfectly if I select the iOS 4.3 SDK but for some reason is not recognizing the folder containing the iOS 5.0 SDK. Some solution? Thanks
回答1:
Xcode>preferences>downloads
If for what ever reason your 5.0 simulator was removed this should allow you to re-add it.

My best advice is to upgrade your Xcode to Xcode 4.3.
XCode 4.3 is the current stable version of Xcode and probably it'll fix you problem.
It's odd to see this happening on Xcode 4.2.1 but I wouldn't waste time trying to figure out what's wrong with this version.
