通过单击UIWebView中的文本来调用Objective-C方法

Question

I query a SQLite db and the query returns some links: I can display them in a UITextView or in a UIWebView .

What I need to know is: is there a way to bind an action to a link inside a UIWebView (or even UITextView )? I don't want to open a webpage, I just want to execute a method of Objective-C as the link was a button. Is this possible?

Answer 1

是的，这可以通过JavaScript来实现，请参阅此文档： 从JavaScript调用Objective-C方法 。

Answer 2

Use the delegate method

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)aRequest navigationType:(UIWebViewNavigationType)navigationType

and check for UIWebViewNavigationTypeLinkClicked , then inspect the [aRequest URL] to determine what the link action should be.
