/**
    Helpful method to dismiss ALL view controllers presented on top of a 
    root view/navigation controller.
    
    This method is useful if you have a variable number of view controllers
    that you'd need to dimiss to return to a base view. Used for my purposes 
    from the AppDelegate class during the process of handling the opening of
    a URL scheme.
    
    This method also relies on implementing a category on UIViewController

# Create an .xcarchive and an .ipa file from the command line (in order to build the ipa without a provisioning profile).
# It was build with 2 successive commands, one to create the .xcarchive file, and the second to build the actual ipa file.
# Your "SchemeName" here is typically the name of your app.

# To create the .xcarchive file:
xcodebuild -scheme SchemeName clean archive -archivePath build/SchemeName


# To create the .ipa file:
xcodebuild -exportArchive -exportFormat ipa -archivePath "build/SchemeName.xcarchive" -exportPath "build/SchemeName.ipa"
