Return YES to allow both to recognize simultaneously. The default implementation returns no (by default No. Gestures can be recognized simultaneously)

That means, return yes, allow both to handle gesture interaction, (if it is webview, you can add a click gesture, but do not affect the webview scrolling gesture), return no, do not accept external gestures

//

Note:returning YES guaranteed to allow simultaneous recognition. Returning guaranteed to prevent simultaneous recognition, as the other gesture ' s delegate may return YES
