What files in an Xcode iOS project should I tell Mercurial to ignore?

When programming an iOS application, there are many files Xcode deals with. I've noticed when I'm programming, the .xcodeproj file is always being modified. What I'm wondering is whether or not the .xcodeproj file should be ignored by Mercurial or not. A开发者_StackOverflow中文版lso, are there any other files that should be ignored by Mercurial?

I usually ignore these files:

.DS_Store
*.swp
*~.nib
build/
*.pbxuser
*.perspective
*.perspectivev3
*.project.xcworkspace
*.xcuserdata
*.mode1v3
*.mode2v3
