尝试在你的 AppDelegate.m 中加入这个:

在顶部导入:

#import 

并将其用于应用程序:openurl: sourceapplication: annotation

- (BOOL)application:(UIApplication*)application openURL:(NSURL*)url sourceApplication:(NSString*)sourceApplication annotation:(id)annotation{如果(！网址){返回否；}[[FBSDKApplicationDelegate sharedInstance] application:application openURL:url sourceApplication:sourceApplication annotation:annotation];返回是；}

这使用 Facebook SDK 来处理 openurl，而不是自定义处理程序.

这将触发您定义的委托方法，然后您可以继续提醒用户或做任何您想做的事情.

同样在您的 info.plist 中，URLSchemes 值需要与您在 Facebook 输入具有自定义方案的 URL"中的值相同.例如，如果您在 Facebook 对话框的带有自定义方案的 URL"中有 myapp://，那么您的 URLScheme 将是 myapp (你目前有action)

所做的只是让 Safari 知道如果您在 URL 栏中调用 myapp:// 那么它应该打开您的应用程序.除非您向应用传递参数，否则 Facebook 屏幕中 myapp:// 之后不需要任何内容​​.

确保在您的开发者设置中(

您可以为 iPhone 使用任何应用程序 ID(来自 iTunes Connect 的应用程序 ID，实际上称为Apple ID").iPad 应用 ID(只需确保它是来自应用商店的有效 ID，名称不必匹配)并为您的应用使用捆绑 ID.iPhone & 的编号iPad ID可以相同.这很重要，因为如果没有这个，Facebook 不会向用户发送通知，因为如果用户没有下载应用程序，它不知道将用户发送到哪里.将其放入并发送另一个通知，它应该可以工作.

使用 Facebook 的快速入门"创建应用邀请链接时，请确保您在 iOS 框中正确设置了参数.这是设置应该是什么样子的示例.这是看起来像 https://fb.me/6344111666661512

具有自定义方案的 URL"必须与 info.plist 中的任何内容相同 - 如果您的 myapp 中有 myapp，请使用上面的答案code>info.plist 在 URLSchemes 下，您可以将myapp://"放在 Facebook具有自定义方案的 URL"中.应用程序名称可以是任何内容，仅用于显示.虽然它说App Store Id"是可选的，但它是必需的.确保在此处使用与上面设置iPad 商店 ID"和iPhone 商店 ID"相同的方法.这会告诉 Apple，如果用户没有您的应用，就将其推送到 iTunes 商店.

I had implemented Facebook App invites in Demo Application. It worked fine but did not get notification.

I have added all detail in my question, now can anyone tell me what is the issue in my code and what should I do to resolve this. I have created test users for testing this app.

This code works fine, it launches a dialogue box, showing the friend list and also shows that the app invite is sent but when I check it in friends account it doesn't show any notification.

My Info.plist File

I think I have a mistake in info.plsit under URL Type (URL Schemes). I had written action which is the name of the method but I don't have any idea what I should write in this column.

Appdelegate.m

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url   sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation {
    BFURL *parsedUrl = [BFURL URLWithInboundURL:url sourceApplication:sourceApplication];
    if ([parsedUrl appLinkData])
    {
        NSURL *targetUrl = [parsedUrl targetURL];
        [[[UIAlertView alloc] initWithTitle:@"Received link:"
                                    message:[targetUrl absoluteString]
                                   delegate:nil
                          cancelButtonTitle:@"OK"
                          otherButtonTitles:nil] show];
    }
        return YES; }

ViewController.h

Getting result null when appInviteDialog:(FBSDKAppInviteDialog *)appInviteDialog didCompleteWithResults:(NSDictionary *)results called

- (IBAction)action:(UIButton *)sender
{

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

    [FBSDKAppInviteDialog showFromViewController:self withContent:content delegate:self];
}

 - (void)appInviteDialog:(FBSDKAppInviteDialog *)appInviteDialog didCompleteWithResults:(NSDictionary *)results
{
    NSLog(@" result %@",results);
}
- (void)appInviteDialog:(FBSDKAppInviteDialog *)appInviteDialog didFailWithError:(NSError *)error
{
    NSLog(@"error =  %@", error);
    NSString *message = error.userInfo[FBSDKErrorLocalizedDescriptionKey] ?:
    @"There was a problem sending the invite, please try again later.";
    NSString *title = error.userInfo[FBSDKErrorLocalizedTitleKey] ?: @"Oops!";

    [[[UIAlertView alloc] initWithTitle:title message:message delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show];

}

Try having this in your AppDelegate.m:

Import this at the top:

#import <FBSDKCoreKit/FBSDKCoreKit.h>

And use this for the application: openurl: sourceapplication: annotation

- (BOOL)application:(UIApplication*)application openURL:(NSURL*)url sourceApplication:(NSString*)sourceApplication annotation:(id)annotation
{
    if (!url) {
        return NO;
    }

    [[FBSDKApplicationDelegate sharedInstance] application:application openURL:url sourceApplication:sourceApplication annotation:annotation];

    return YES;
}

This uses the Facebook SDK to handle openurls instead of a custom handler.

This will trigger the delegate methods you have defined and then you can proceed to alert the user or do whatever you want.

Also in your info.plist the URLSchemes value needs to be the same as what you have in your Facebook input 'URL with a custom scheme'. For example if you have myapp:// in your 'URL with a custom scheme' on the Facebook dialogue then your URLScheme would be myapp (where you currently have action)

All that does is lets Safari know that if you call myapp:// in the URL bar then it should open your app. Unless your passing parameters to the app you don't need anything after the myapp:// in the Facebook screen.

Make sure in your developer settings (https://developers.facebook.com/apps/{app-id}/settings/) you have added the platform iOS, and have set up both a bundle id and the iPhone store id and iPad store id.

You can use any app id (the one from itunes connect, actually called 'Apple id') for the iPhone & iPad app id (just make sure its a valid one from the app store, names don't have to match) and use your bundle id for your app. The number for the iPhone & iPad id can be the same. This is crucial as Facebook doesn't deliver the notification to the user without this because it doesn't know where to send the user if they haven't downloaded the app. Put this in and send another notification and it should work.

When using Facebook's 'Quick Starts' to create the app invite link, make sure you are setting up the parameters in the iOS box correctly. Here is an example of what the setup should look like. This is the link that looks like https://fb.me/634411166661512

The "URL with a custom scheme" needs to be the same whatever you have in your info.plist - using the answer above if you have myapp in your info.plist under URLSchemes you would put "myapp://" in the Facebook "URL with a custom scheme". The app name can be anything, that's just for display. Although it says "App Store Id" is optional, it is required. Make sure you use the same one in here as you did above where you set your "iPad Store Id" and "iPhone Store Id". This tells Apple to push the user to the itunes store if they do not have your app.
