How to AirPrint Text and Images

I have the code below that prints the contents of a textview but i would like to print the contents of a UIView. How could I do this?

Thanks

        var pic:UIPrintInteractionController = UIPrintInteractionController.sharedPrintController()!
        var viewpf:UIViewPrintFormatter = textView.viewPrintFormatter()

        pic.delegate = self
        pic.showsPageRange = true
        pic.printFormatter = viewpf

You don't need a type declaration when you are assigning a variable.

var pic = UIPrintController.... is sufficient. Swift will derive the type from the assigned value. It is necessary if you are just declaring a variable and not assigning it a value.

UIViewPrintFormatter supports UIWebView, UITextView, and MKMapView. This is not available for any generic UIView. So if you can get your UIView to render properly inside of a UIWebView then you can use the proper values there.

Depending on the content of your view, you may be able to just duplicate it in HTML/CSS files locally then use those as the source for the webView and then you'd be able to use webView's printFormatting just as you do above of the textView.

Also UIPrintInteractionController.canPrintData() could be useful for testing this.
