This has been annoying me for a while in several XCode projects. I really don't like to have compiler warnings when I build. When I build my current project, I get the following warning from a bunch of XIB files:
/.../CaseInformationView.xib:3:0 UIScrollView's 'Bounce Zoom' option will be ignored on iPhone OS versions prior to 2.1.
Since I'm building for 3.0, I don't care if it will be ignored. If I want to use the Bounce Zoom option in my XIB file, how can I not see this warning?

In IB, select "Document Info" from the Window menu and set your Deployment target to 3.0.
EDIT: In more current versions of Xcode
- Choose the xib
- Go to the File Inspector
- In the Interface Builder Document section, set Deployment and Development
- Also, set Deployment Target on Project's Summary page (choose main project, then Summary tab)
