Question

As the title suggests my activity indicator in the status wont stop animating.

Ive done some research on here and not sure what im doing wrong…

In my Apps delegate I have

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{


UIApplication* app = [UIApplication sharedApplication];
app.networkActivityIndicatorVisible = NO;

In my view controller.m I want to call the activity indicator

 NSString *web = @"http://google.com";
    NSURL *url = [NSURL URLWithString:web];
    NSURLRequest *requestUrl = [NSURLRequest requestWithURL:url];
    [toweb loadRequest:requestUrl];

    UIApplication* app = [UIApplication sharedApplication];

     app.networkActivityIndicatorVisible = YES; <<<<<<<<<<<<<<<<<<<<<

Now heres the problem im trying to hide it again with:

- (void)DidFinishLoad:(UIWebView *)toweb{
 [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
 }    

}

Any advice appreciated

Answer 1

looks like your UIWebViewDelegate method name is wrong, it should be

-(void)webViewDidFinishLoad:(UIWebView *)webView {
      [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
}

not

- (void)DidFinishLoad:(UIWebView *)toweb{
     [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
}    

Hence when the UIWebView tries to call its delegate method, there is no method declaration so your class is not being notified that the web view has finished loading.

Also make sure you have set your class as the delegate

toweb.delegate = self

and in your .h file

@interface viewcontroller : UIViewController <UIWebViewDelegate>

Note that in the delegate callback method, the webView parameter is a reference to the webview that has finished loading (in this case its the one you’ve called toweb) This is a different pointer to the same UIWebView object, so it doesn’t need to have the same name as your local declaration/handle to the web view
