+
+ [iOS] Crash in _endPotentialTapAndEnableDoubleTapGesturesIfNecessary
+ https://bugs.webkit.org/show_bug.cgi?id=153326
+ <rdar://problem/24264339>
+
+ Reviewed by Anders Carlsson.
+
+ UIKit's UIGestureRecognizer could call back into the WKContentView
+ after the associated WKWebView has disappeared. The fix is to
+ explicitly null the WKWebView reference as we deallocate.
+
+ * UIProcess/API/Cocoa/WKWebView.mm:
+ (-[WKWebView dealloc]): Tell the WKContentView we are going away.
+ * UIProcess/ios/WKContentView.h:
+ * UIProcess/ios/WKContentView.mm:
+ (-[WKContentView _webViewDestroyed]):
+ * UIProcess/ios/WKContentViewInteraction.mm:
+ (-[WKContentView _endPotentialTapAndEnableDoubleTapGesturesIfNecessary]):
+ Only do something if the WKWebView is still around.
