+
+ [iOS] Add long press support for links in WKPDFView
+ https://bugs.webkit.org/show_bug.cgi?id=138357
+
+ Reviewed by Dan Bernstein.
+
+ Use WKActionSheetAssistant to show a link action sheet in response to long-pressing on a link. Have WKPDFView
+ conform to WKActionSheetAssistantDelegate in order to respond to the open and copy actions as well as to
+ provide the link's URL and position information to WKActionSheetAssistant. The long-pressed link is highlighted
+ for .75 seconds before the sheet is displayed in order to match UIWebPDFView.
+
+ * UIProcess/ios/WKActionSheetAssistant.h: Made protocol methods that WKPDFView doesn't implement optional.
+ * UIProcess/ios/WKActionSheetAssistant.mm:
+ (-[WKActionSheetAssistant updatePositionInformation]): Checked if delegate responds to
+ updatePositionInformationForActionSheetAssistant: before calling.
+ (-[WKActionSheetAssistant _createSheetWithElementActions:showLinkTitle:]): Checked if delegate responds to
+ actionSheetAssistant:willStartInteractionWithElement: before calling.
+ (-[WKActionSheetAssistant cleanupSheet]): Checked if delegate responds to actionSheetAssistantDidStopInteraction:
+ before calling.
+ * UIProcess/ios/WKPDFView.h: Conformed to WKActionSheetAssistantDelegate.
+ * UIProcess/ios/WKPDFView.mm:
+ (-[WKPDFView web_initWithFrame:webView:]): Instantiated a WKActionSheetAssistant and set self as its delegate.
+ (-[WKPDFView _highlightLinkAnnotation:forDuration:completionHandler:]): Moved highlight drawing to here from
+ annotation:wasTouchedAtPoint:controller: in order to be reused for long-press.
+ (-[WKPDFView _URLForLinkAnnotation:]): Moved URL creation to here from annotation:wasTouchedAtPoint:controller:
+ in order to be reused for long-press. Generated an absolute URL since this URL might go into the pasteboard.
+ (-[WKPDFView annotation:wasTouchedAtPoint:controller:]): Changed to call
+ _highlightLinkAnnotation:forDuration:completionHandler: and _URLForLinkAnnotation:.
+ (-[WKPDFView annotation:isBeingPressedAtPoint:controller:]): Set values on _positionInformation and called
+ -[WKActionSheetAssistant showLinkSheet] after showing a highlight for .75 seconds.
+ (-[WKPDFView positionInformation]): Returned _positionInformation.
+ (-[WKPDFView performAction:]): Added a UTF-8 text and URL representation of the pressed URL to the pasteboard.
+ (-[WKPDFView openElementAtLocation:]): Called WebPage::navigateToURLWithSimulatedClick().
+ (-[WKPDFView actionsForElement:defaultActions:]): Returned actions from UIClient::actionsForElement().
+ (-[WKPDFView _createHighlightViewWithFrame:]): Deleted.
