I am seeing "Base SDK missing" error for some of the projects I open in XCODE.

Go to the project settings, and select as "Base SDK" "iOS 4.2" or whatever is the current version. 转到项目设置，然后选择“ Base SDK”，“ iOS 4.2”或当前版本。 If you want compatibility to older iOS versions in the AppStore, select as "iOS Deployment Target" the desired lowest version, but be careful when using apis which aren't aren't available in that version ( respondsToSelector: is your friend). 如果要与AppStore中的较旧iOS版本兼容，请选择所需的最低版本作为“ iOS部署目标”，但是在使用该版本中不可用的api时要小心（ respondsToSelector:是您的朋友）。

可以在“常规”选项卡下的“项目信息”中设置基本SDK。
