Question

我正在尝试在FBAPPInvite中进行深层链接，但我给出了以下错误

我应用此代码

NSMutableDictionary *params = [[NSMutableDictionary alloc] init];
    [params setObject:@"1452" forKey:@"station_id"];
    [params setObject:@"https://s3-us-west-1.amazonaws.com/myapp/radiostation.jpg" forKey:@"$og_image_url"];
    [params setObject:@"Check out my favorite station on iHeartRadio" forKey:@"$og_description"];
    [params setObject:@"Wild 94.9" forKey:@"$og_title"];

    [[Branch getInstance] getShortURLWithParams:params
                                     andChannel:@"facebook"
                                     andFeature:@"app_invite"
                                    andCallback:^(NSString *url, NSError* error) {
                                        FBSDKAppInviteDialog *inviteDialog = [FBSDKAppInviteDialog new];
                                        if ([inviteDialog canShow]) {
                                            inviteDialog.content =[[FBSDKAppInviteContent alloc] init];
                                            inviteDialog.content.appLinkURL = [NSURL URLWithString:url];
                                            inviteDialog.content.appInvitePreviewImageURL = [NSURL URLWithString:@"https://s3-us-west-1.amazonaws.com/host/zackspic.png"];

                                            [inviteDialog show];
                                        }
                                    }];

我得到了我的错误解决方案

我在branch.io

中设置了所有参数

[[Branch getInstance] getShortURLWithParams:nil
                                     andChannel:@"facebook"
                                     andFeature:@"app_invite"
                                    andCallback:^(NSString *url, NSError* error) {
                                        FBSDKAppInviteDialog *inviteDialog = [FBSDKAppInviteDialog new];
                                        if ([inviteDialog canShow]) {
                                            inviteDialog.content =[[FBSDKAppInviteContent alloc] init];
                                            inviteDialog.content.appLinkURL = [NSURL URLWithString:url];
                                            inviteDialog.content.appInvitePreviewImageURL = [NSURL URLWithString:@"https://s3-us-west-1.amazonaws.com/host/zackspic.png"];

                                            [inviteDialog show];
                                        }
                                    }];

您必须在自己的网站中添加应用链接网址的元标记。

<html>
<head>
    <meta property="al:ios:url" content="example://applinks" />
    <meta property="al:ios:app_store_id" content="12345" />
    <meta property="al:ios:app_name" content="Example App" />
    <meta property="og:title" content="example page title" />
    <meta property="og:type" content="website" />
    <!-- Other headers -->
</head>
<!-- Other HTML content -->
</html>
</head>
