FBConnect dialog.attachment?

[JavaWizKid]

Is there any example code explaining how to change Facebooks API existing code to make it yours?

FBStreamDialog* dialog = [[[FBStreamDialog alloc] init] autorelease];
	dialog.delegate = self;
	dialog.userMessagePrompt = @"Example prompt";
	dialog.attachment = @"{\"name\":\"Facebook Connect for iPhone\","
		"\"href\":\"http://developers.facebook.com/connect.php?tab=iphone\","
		"\"caption\":\"Caption\",\"description\":\"Description\","
		"\"media\":[{\"type\":\"image\","
			"\"src\":\"http://img40.yfrog.com/img40/5914/iphoneconnectbtn.jpg\","
			"\"href\":\"http://developers.facebook.com/connect.php?tab=iphone/\"}],"
		"\"properties\":{\"another link\":{\"text\":\"Facebook home page\",\"href\":\"http://www.facebook.com\"}}}";
	// replace this with a friend's UID
	// dialog.targetId = @"999999";
	[dialog show];

That doesn't make any sense to me :S

Thanks

Attachment (Streams) - Facebook Developer Wiki

has information on which field is what...it's JSON format, so in general you have something like:

"title":"value of title","src":"value for src"..."n","value for n"

but many of the extra \'s in the string are to escape the quotes so it doesn't terminate the string
