How to detect click on image in UIWebView in iOS?

Question

iOS

It is necessary to execute a certain method on clicking on the image

Answer 1

You can execute your JS code in the context of the UIWebView page https://developer.apple.com/library/ios/documentat...
In this JS code, for example, hang handlers on the onclick event on all pages and pass them to this handler the element itself or, for example, a link to the image itself. In the event handler, you can redirect to some url like mypotocol://myurl.
And now, in the webView:shouldStartLoadWithRequest:navigationType: delegate method, define the protocol and url, and if it matches mypotocol and / or myurl, then perform the necessary actions, while returning NO.
