targeting iOS

I was wondering how clang can target the iOS platform. My instinctive approach would have been to use -ccc-host-triple arm-apple-darwin10 , but I recently discovered that the arm-apple-ios triple is used by the apple "official" compiler.
What is the recommended option?

Assuming you're on OS X, the supported way to invoke clang targeting
iOS is something like "clang -arch armv7 -mios-version-min=5.0
-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk/"
.
