Subscribe to WebCal URL in iOS 4.0

Question

In my iPhone application, I have this button that opens the webcal: // URL in a UIWebView as follows:

#define kHostName @"webcal://www.markthisdate.com/kalender/World_Cup_Football_2010_Match_Schedule_10251.ics"

    - (IBAction)putInCalendar:(id)sender{
     NSURL *url = NULL;
     url = [[NSURL alloc] initWithString:kHostName];
     NSURLRequest *request = [[NSURLRequest alloc] initWithURL: url];
     [webView loadRequest: request];
     [request release];
     [url release];
    }

In iOS 3.x, this triggers the sequence of the “Subscribe to Calendar ...” dialogs, etc., similar to what happens if you open the same URL in Mobile Safari: the associated event is added as a subscription to the iPhone calendar.

Somehow, in iOS 4.0, this does not work from my application, although opening a URL in Mobile Safari in iOS 4.0 works.

Can someone explain to me why this does not work, but even better: what would be the appropriate approach of iOS 4.x to this feature.

[[UIApplication sharedApplication]openUrl:[NSUrl urlWithString:[NSString stringWithFormat:@"%@",KHostName];
