(iphone) build xcode4 project from command line

Question

I've used to build my project with xcodebuild -proj MyProject.xcodeproj -target MyTarget - configuration Debug -sdk iphonesimulator4.3

this works(it builds fine) but when I hit run in xcode, it recompiles.
(with xcode3, there was no need to rebuild once I build using command line)

I suspect xcode build use workspace/scheme rather than project/target.

How do I find out the workspace name that my current xcode project is using?

Thank you

Chetan's links gave me directions what to look for.

xcode4 stores build output in ~/Library/... whereas xcodebuild -project.. saves build output in project's build directory. (if you want the workspace capability, you can't use the build directory for build output)

I created a workspace containing my project and ran xcodebuild -workspace myWorkSpace -scheme myScheme

this saves build output in ~/Library/...../ Debug-iphoneos

whereas xcode4 run button from the same workspace and same scheme saves output in ~/Library/..../ Debug-iphonesimulator

any guess on why xcodebuild command uses Debug-iphoneos? :(

xcodebuild -workspace myWorkSpace -scheme myScheme -sdk iphonesimulator4.3
specifying sdk solved it

I know it isn't strictly the answer to your question, but you can configure the output directory of your build using the CONFIGURATION_BUILD_DIR environment variable.
