What determinates the options in property list of a .plist file?

When I try to ad开发者_JS百科d an item to an existing iPhone Info.plist, the options in the list is not iPhone-relevant (e.g. "Application is visible in Classic" which seems to be some desktop OS stuff).

How can I get back the proper list of choices for iPhone? Thanks!

p.s. I found this when editing the avTouch sample project's Info.plist file.

This might not be an exhaustive list of all iPhone-relevant entries, but maybe a good start: Recommended Keys for iPhone Applications and the Bundle Programming Guide's section on iPhone plist keys.

Not sure if you can limit the choice in xcode's plist editor to only include iPhone-related keys.
