If you have a Web View in your view you can call a custom action when the user taps on a link in that UIWebView instance.

Here’s how…

Set the delegate of that UIWebView class instance on your instance of UIViewController class. Now just copy & paste the following code into your class.  This code implements the UIWebView instance and adds a call to the custom action (method).

- (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType {
if(navigationType == UIWebViewNavigationTypeLinkClicked) {
if (overrideLinksSwitch.on == TRUE) {
[self myMethodAction];
[myWebView stopLoading];
return YES;
}
else {
<>return YES;
}
}
return YES;
}
