Question

I have 2 WebViews in my application. one is loading a youtube video and the other is loading an events calendar. I want to show a custom ‘Loading’ image until the data from the web views are done loading.

I am trying

while([youtubeView isLoading]){
        NSLog(@"youtubeVideo is loading");
        [loadingImage setHidden:NO];
    }
    [loadingImage setHidden:YES];

In viewDidLoad but it doesn’t work.

Whats the best way to accomplish what I am trying to achieve?

Cheers, Beers on me.

Answer 1

Use below method of UIWebViewDelegate. It get called once webView finish loading.

- (void)webViewDidFinishLoad:(UIWebView *)webView
    {
        if(youtubeView isEqual:webView)
        {
           loadingImage.hidden = YES;
        }
    }

Also note that your class need to conform to UIWebViewDelegate and both your webviews should set delegate equal to object of that class.

@interface YourViewController : UIViewController <UIWebViewDelegate>
{
    UIWebView *youtubeView;
}
@end

inside method where you create UIWebView youtubeView

youtubeView.delegate = self;
