Answer 1

For Facebook SDK Invite, you need create a custom App Link. Facebook gave complete documentation for invites. Refer this link to create App link . Facebook provides a App Link Tool to create your custom app link. In tool to create App Link, you need add some Custom URL scheme, App store ID and App name. Custom URL scheme looks like this: youAppName://fbFacebookAppID . We also add fbFacebookAppID in .plist under URLScheme in URLTypes

Answer 2

AppLinkUrl is not the url of your app in the market.

• You need to make your own appLinkUrl and put it in your info.plist(see: http://iosdevelopertips.com/cocoa/launching-your-own-application-via-a-custom-url-scheme.html ) that you'll be using for deepLinking.
• Then after you declare it on your info.plist, you must have at least an html web page where you can put the meta tags for the appLinks of ios or android( https://applinks.org ). Take note the the appLinkUrl that you have put on your info.plist should be the same on your meta property="al:ios:url
• Debug your website url and check your meta tags using facebook url debugger. Press "Fetch new scrape information" to update the meta tags for any changes on it.
• Use the link of your webpage that has the meta tags and use it like on the sample on facebook docs

  FBSDKAppInviteContent *content =[[FBSDKAppInviteContent alloc] init]; content.appLinkURL = [NSURL URLWithString:@"your_website_link_with_metatags"];

• Just need to make sure your meta tags have the right information.
