I'm developing a cross-platform mobile app using Cordova, focussing mainly on iOS in the development stage.

For my development process it would be ideal if I could start my Cordova app directly from the command line and have it load into a specified emulator. I can do this by running the following from the project root directory:

$cordova run --debug --emulator iOS

This works fine, and results in an iOS-simulator running my app in a simulated iPhone 4 Retina with iOS 7.0.3

Besides this simulated device, I would also like to test on (for instance) an iPad. I have these emulation images installed, and I can start my app in them manually in Xcode. Also, the command list-emulator-images (located in project_dir/platforms/ios/cordova/lib) gives the following output:

"iPhone Retina (3.5-inch)"
"iPhone Retina (4-inch)"
"iPhone Retina (4-inch 64-bit)"
"iPhone"
"iPad"
"iPad Retina"

However, the thing is: I can't seem to figure out how to start the emulator in anything other than the default (which appears to be the iPhone Retina (4-inch) emulation image). The relevant output of cordova help gives the following information:

run [--debug|--release]
    [--device|--emulator|--target=FOO]
    [PLATFORM] ............................ deploys app on specified platform devices / emulators

I've tried things like the following:

cordova run --debug --emulator=iPad iOS

And many variations thereof, but no luck. Every time it starts in the same emulator.

The documentation for the command-line tool doesn't offer any information in this regard, and an extensive Google-search also failed to turn up anything. Am I missing something trivial? Or am I trying to do something weird? I really hope someone here has experience with this, and can provide some answers.

Thanks very much in advance!

edit: forgot to mention explicitly; I'm doing all this on a Mac. As mentioned earlier, running the app in different emulators/simulators in Xcode works fine.
