UIWebView does not load the URL - iphone

Question

I have very small problem while loading the URL in UIWebView.
I have one UIButton, on clicking of it, I add the UIView which contains UIWebView, UIButton & Title bar. Code used is as follows -
[self.view addSubview:vwOnline];
vwOnline.bounds = self.view.bounds;
//Load webview
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"%#", objWine.strOnlineURL]];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[wbvwOnline loadRequest:request];
- (void)webViewDidStartLoad:(UIWebView *)webView
{
//Show activity indicator
[indicator startAnimating];
}
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
//Remove Activity indicator
[indicator stopAnimating];
[indicator removeFromSuperview];
}
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error
{
NSLog(#"Error - %#", error);
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Find A Vino" message:#"Error while loading request." delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert show];
alert.tag = 1;
//Remove Activity indicator
[indicator stopAnimating];
[indicator removeFromSuperview];
}
By doing above code, most of times the UIWebView does not loads the URL which I passed in the object objWine.strOnlineURL. If I clicked the back button & again clicked on the button to load the URL, it goes into the - (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error delegate method of UIWebView.
If anyone knows the solution, then please help me.

Answer 1

Instead of adding your webview on your button click each time. Why don't you add your webview into your viewDidLoad and hide and show it in your button click.

Answer 2

when you are going back, make request to nil and load empty htmlstring to webview. One more thing, remove [indicator removeFromSuperview]; line from
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error
-(void)webViewDidFinishLoad:(UIWebView *)webView

Answer 3

use
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"http://www.google.com"]];
if it is work fine then check objWine.strOnlineURL
otherwise it is clear :)
