CanPerformActionWithSender called twice

[bwestcott]

I am trying to see if I can implement the "Copy" functionality in UIWebView, so I modified your code to insert "Can performActionWithSender" code. However, I noticed that it is being called twice for every potential action (Cut,delete, etc.) Is this something that just happens with UIWebView?

I'll have to look into this a little more to be sure, but I think UIWebView already provides a default copy functionality in the webview that works systemwide...

The copy functionality works OK. My problem is that "CanPerformAction" is called twice (even though I don't have to do anything in the call). The code I inserted into your code to test this was:

• (BOOL)canPerformAction:(SEL)action withSender:(id)sender {
  NSLog(@"can PerformActionWithSender %@",NSStringFromSelector(action));
  }

Also, "wsPasteboardChangedNotification" is called twice when a copy is selected from the webView when I insert code to trap the notification.
