UIWebView without Copy/Paste when displaying PDF files

Question

I have tried to disable Copy/Paste in UIWebView by using a category and overriding canPerformAction and returning NO for copy, cut and paste selectors.

It worked

Answer 1

Here is a modification to Zubaba's answer in Swift 3 that ended up working for me to eliminate warning. I changed assignment longPress.delegate = self to longPress.delegate = self as? UIGestureRecognizerDelegate.

    let longPress = UILongPressGestureRecognizer(target: self, action: #selector(handleLongPress))
    longPress.allowableMovement = 100
    longPress.minimumPressDuration = 0.3
    longPress.delegate = self as? UIGestureRecognizerDelegate
    longPress.delaysTouchesBegan = true
    longPress.delaysTouchesEnded = true
    longPress.cancelsTouchesInView = true
    webView.addGestureRecognizer(longPress)
    webView.scrollView.addGestureRecognizer(longPress)

    webView.loadRequest(request)
