FBSDKAppInvite回拨未进入ios

我是IOS初学者，希望通过facebook邀请朋友使用我的应用程序。我使用了facebook（4.0）的新框架，我发现对于邀请，我需要使用FBSDKAppInvite

我在“应用程序链接托管API快速入门”中设置了深度链接

我使用以下代码进行应用程序邀请

#pragma mark
#pragma mark - Share via facebbok
- (IBAction)btnShare:(id)sender
{

    FBSDKAppInviteContent *content =[[FBSDKAppInviteContent alloc] init];
      content.appLinkURL = [NSURL URLWithString:@"https://fb.me/863075563772717"];
    //optionally set previewImageURL


    // present the dialog. Assumes self implements protocol `FBSDKAppInviteDialogDelegate`
    [FBSDKAppInviteDialog showWithContent:content
                                 delegate:self];   // Do any additional setup after loading the view, typically from a nib.
}

-(void)appInviteDialog:(FBSDKAppInviteDialog *)appInviteDialog didCompleteWithResults:(NSDictionary *)results
{
    NSLog(@"result::%@",results);
}
-(void)appInviteDialog:(FBSDKAppInviteDialog *)appInviteDialog didFailWithError:(NSError *)error
{
    NSLog(@"error::%@",error);
}

并在下面的方法中处理回调

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {

    // Check if the handler knows what to do with this url
    BFURL *parsedUrl = [BFURL URLWithInboundURL:url sourceApplication:sourceApplication];
    if ([parsedUrl appLinkData]) {
        // this is an applink url, handle it here
        NSURL *targetUrl = [parsedUrl targetURL];
        [[[UIAlertView alloc] initWithTitle:@"Received link:"
                                    message:[targetUrl absoluteString]
                                   delegate:nil
                          cancelButtonTitle:@"OK"
                          otherButtonTitles:nil] show];
    }
    return YES;
}

但是我在[parsedUrl appLinkData]

我不明白我做错了什么。我还在Plist中加入了URLScheme

任何帮助都是可观的

更新

若我使用了下面的方法，那个么我在委派方法中获得了成功，但invite并没有发送给收件人

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {

    // Check if the handler knows what to do with this url
    return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                          openURL:url
                                                sourceApplication:sourceApplication
                                                       annotation:annotation];
}

如果您已为iOS启用App Center，我会检查您的Facebook应用程序设置，我还会检查您的设置中是否有有效的itunes store id，最后检查您的朋友是否尚未安装该应用程序，否则不会按照此处的指定发送邀请：
