Launch iOS app programmatically (or from within code)?

Hi Guys,

Is there any way to launch the application from the code in an iOS device using the iOSDriver? Like we do with startActivity method on AndroidDriver? I need to also install the app programmatically (which I am planning to do with the installApp() command by giving the .ipa path) and then need to launch it. I really don’t want to pass the app path or bundle id as part of desired caps (the app wont be installed when the appium server is started). Is this possible?
