Sharing web page url to Facebook - facebook

Question

I try to share a web page url with NSSharingServicePicker to Facebook, but it appears on my FB wall not as a web page url(with description and so on), but just like a link.
My code is very simple.
- (IBAction)share:(id)sender
{
NSURL* url = [NSURL URLWithString:#"http://itunes.apple.com/us/app/travel-route-planner/id504536611"];
NSSharingServicePicker *sharingServicePicker = [[NSSharingServicePicker alloc] initWithItems:[NSArray arrayWithObjects:url, nil]];
sharingServicePicker.delegate = self;
[sharingServicePicker showRelativeToRect:[shareButton bounds]
ofView:shareButton
preferredEdge:NSMinYEdge];
}
I know it could be done.
Safari shares web pages the way i need.

Answer 1

I took a look at the source code on the website you're trying to share, and ran it through the Facebook Object Debugger. Facebook is pretty picky when it comes to the defined protocol, so I'd recommend changing your URL from http:// to https:// as the secure URL is what iTunes has decided to set as their og:url property. See here:

I found the answer on Apple Dev forums.
You need to add image to NSURL using following NSSharingServiceDelegate methods
- (NSRect) sharingService: (NSSharingService *) sharingService
sourceFrameOnScreenForShareItem: (id<NSPasteboardWriting>) item
{
if([item isKindOfClass: [NSURL class]])
{
//return a rect from where the image will fly
return NSZeroRect;
}
return NSZeroRect;
}
- (NSImage *) sharingService: (NSSharingService *) sharingService
transitionImageForShareItem: (id <NSPasteboardWriting>) item
contentRect: (NSRect *) contentRect
{
if([item isKindOfClass: [NSURL class]])
{
return [NSImage imageNamed:#"image.png"];
}
return nil;
}
don't forget to set the delegate for your NSSharingService
- (id < NSSharingServiceDelegate >)sharingServicePicker:(NSSharingServicePicker *)sharingServicePicker delegateForSharingService:(NSSharingService *)sharingService
{
return self;
}
