UIActivityIndicatorView Not disappearing

This seems to be a very simplistic issue, but I literally cannot get it working.

I have a section of my app which takes my user to a WebView displaying my site. As part of the built in 'browser' experience i want a UIActivityIndicator located to let the user know that the site is loading. Obviously when this is done i want the indicator to disappear.

At the minute, the activity indicator animates, but then keeps animating forever and does not stop or disappear.

The code I am using in .h is as follows;

@interface AppSupportWebsite : UIViewController <UIWebViewDelegate> {

    IBOutlet UIActivityIndicatorView *activityIndicator;

}

@property (nonatomic, retain) UIActivityIndicatorView *activityIndicator;

@end

And within my .m file I have the following; (abbreviated to just show the activity indicator specific code)

@synthesize activityIndicator;


- (void)webViewDidStartLoad:(UIWebView *)webView {
    [activityIndicator startAnimating];

}

- (void)webViewDidFinishLoad:(UIWebView *)webView {
    [activityIndicator stopAnimating];
}

I have created an activity indicator within Interface Builder and through Files Owner connected the activityIndicator IBOutlet to the white activity indicator through IB but it just wont disappear.

- (void)webViewDidStartLoad:(UIWebView *)webView {
    [activityIndicator startAnimating];
}

It is possible to run above code multiple time it your website have multiple redirects. so I would not suggest to put this line in this delegate method. I would suggest to put this in viewWillAppear delegate method of viewController.

-(void)viewWillAppear:(BOOL)animated{
   [activityIndicator startAnimating];
}

Also, make sure you bind UIActivityIndicator in your xib.

Hope this help.

This is just a stab in the dark, but you may be having issues because the UIWebView Delegate is being called from a different thread other than the main thread. So you may be getting some race conditions as a result.

Give this Grand Central Dispatch Code (GCD) a try and let me know if that works:

- (void)webViewDidFinishLoad:(UIWebView *)webView {
    dispatch_async(dispatch_get_main_queue(), ^(void) {
      [activityIndicator stopAnimating];
    });
}

Can you add an NSLog statement (just something like NSLog(@"Web Finished Loading!");) to the webViewDidFinishLoad method? My guess is that this method is not being called. There could be a few reasons for that. For instance, if you are releasing the webView before you hit the method, it might not call the method at all.
