How would I declare this function?

Question

I'm needing help with this answer from UIWebView - How to identify the "last" webViewDidFinishLoad message?

How would I declare webViewLoads_++; and webViewLoads_--; in the following code:

- (void)webViewDidStartLoad:(UIWebView *)webView {
  webViewLoads_++;
}


- (void)webViewDidFinishLoad:(UIWebView *)webView {
  webViewLoads_--;

 if (webViewLoads_ > 0) {
return;
}

 …
}

Thanks

Should be in instance variable of type int: int webViewLoads_; in the .h file.

The simplest way is to declare an int in your .m (implementation) file, above webViewDidStartLoad::

int webViewLoads_ = 0;

Remember to reset this to 0 when the last load completes:

webViewLoads_--;
if (webViewLoads_ > 0)
{
    return;
}
webViewLoads_ = 0;

As a side note, this should also be reset to zero if the user stops the loading process. – Evan Mulawski Jan 17 '11 at 01:11

You can tell when a webview is really "done" by using the delegate method:

webView:didFinishLoadForFrame:

I know this is a noob question but where would I put that? Would I just do this: - (void) didFinishLoadForFrame:(UIWebView *)webView{ – 0SX Jan 17 '11 at 00:44
@Alan, That could be the reason why I've never seen that in the iOS Docs. ;-) – 0SX Jan 17 '11 at 00:48
Yep, the UIKit WebView (UIWebView) has only but a subset of what is provided to developers targeting OS X. – Alan Zeino Jan 17 '11 at 00:50
