Does anyone know if it is possible to launch edrawings on the iPad using a URL scheme? I've built a custom app for a clients team of engineers which amoungst other things stores some key eDrawing files. I would like to be able to open up the eDrawings viewer app from within my app and pass it the drawing name to display, its a similar way to how you can launch eDrawings from within the mail app on the iPad. The most common way to do this is for software developers to provide a URL scheme that can be called from within other apps this is how you can launch external apps from within another, for example you can launch skype using

-(IBAction)skype {

  NSURL *url = [ [ NSURL alloc ] initWithString: @"skype:john.smith?call" ];

    [[UIApplication sharedApplication] openURL:url];

}

Many Thanks
