In one of my apps I reuse a webview. Each time the user enters a certain view on reload cached data to the webview using the method - (void)loadData:(NSData *)data MIMEType:(NSString *)MIMEType textEncodingName:(NSString *)encodingName baseURL:(NSURL *)baseURL and I wait for the callback call - (void) webViewDidFinishLoad:(UIWebView *)webView. In the mean time I hide the webview and show a 'loading' label. Only when I receive webViewDidFinishLoad do I show the webview.
Many times what happens is I see the previous data that was loaded to the webview for a brief second before the new data I loaded kicks in.
I already added a delay of 0.2 seconds before showing the webview but it didn't help.
Instead of solving this by adding more time to the delay does anyone know how to solve this issue or maybe clear old data from a webview without release and allocating it every time?
