why can't inherit TOWebViewController about towebviewcontroller HOT 5 CLOSED

Inherit...? You mean you're trying to subclass it?

What are you trying to do exactly? I never thought there would be a need to subclass it...

from towebviewcontroller.

Yes i want subclass it, because i need communication with the JavaScript .To this problem, I need more test. In UIWebviewController everything is ok , but when i subclass TOWebViewController, something wrong!

from towebviewcontroller.

Ahh I see!

If all you need to do is JavaScript communication with the UIWebView, you shouldn't have to subclass it. The UIWebView is exposed as a class property for that reason.

TOWebViewController *webController = [TOWebViewContoller alloc] initWithURLString:@"http://www.google.com"];
[webController.webView stringByEvaluatingJavaScriptFromString:@"document.write(\"Hello World\");"];

Something like that should work fine.

I never designed the class with the intention of people subclassing it, so I have no idea what could be happening there (As long as you're calling super in any methods you override, it SHOULD be fine).

In any case, let me know if that still doesn't fix your problem.

from towebviewcontroller.

Thanks. I shouldn't subclass it,if I do that and override shouldStartLoadWithRequest didFailLoadWithError webViewDidFinishLoad, it cause the webView never load end.

from towebviewcontroller.

Ahhh okay. Yep, that would do it.

The TOWebViewController classes already uses the UIWebView's delegate property, so if you override any of those delegate methods and don't call super, it'll break.

That being said, something like this should work:

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
    //Custom code here

    return [super webView:webView shouldStartLoadWithRequest:request navigationType:navigationType];
}
