WebViewDidFinishLoad: Shooting Too Soon?

Question

I am trying to go between loading various web pages by hiding the webView when the page loads. Nevertheless, I see that some sites that use images intensively cause webViewDidFinishLoading to start too fast, and when I show the webView at this point, you will get an idea of ​​the previous page for a second. Any ideas on how to resolve this?

Answer 1

If there is Javascript on the page, you may need to wait for it to complete. The easiest way is to send some javascript to the page to be executed:

-(void) webViewDidFinishLoad:(UIWebView *)webView { NSString *javaScript = @"<script type=\"text/javascript\">function myFunction(){return 1+1;}</script>"; [webView stringByEvaluatingJavaScriptFromString:javaScript]; // done here } 

Having said that, I seem to still see cases where the webview is not completely updated in webViewDidFinishLoad.

Answer 2

I ran into this problem. Although I did not find a solution, I worked on the problem by introducing a delay of 0.5 seconds before showing the UIWebView after calling the delegate method webViewDidFinishLoading.

 - (void)webViewDidFinishLoad:(UIWebView *)webView { [self performSelector:@selector(displayWebView) withObject:nil afterDelay:0.5]; }
