Question

我正在尝试通过AppLinks网址打开Facebook应用，它会打开用户个人资料/页面但不显示按钮“返回参考应用”，我提供“referer_app_link”数据，我已通过此引用生成JSON http://applinks.org/documentation/#applinknavigationprotocol

    NSDictionary *dict = @{
                       @"target_url" : @"fb://profile/USER_ID",
                       @"referer_app_link" : @{
                               @"target_url" : @"MY WEBSITE",
                               @"url" : @"CALLBACK URL",
                               @"app_name" : @"MY APP NAME",
                               @"app_store_id" : @"MY APP STORE ID"
                               }
                       };

NSData *data = [NSJSONSerialization dataWithJSONObject:dict options:0 error:nil];
NSString *jsonString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

jsonString = [jsonString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

NSString *stringUrl = [NSString stringWithFormat:@"fb://applinks?al_applink_data=%@",jsonString];
NSLog(@"String url is %@",stringUrl);
NSURL *url = [NSURL URLWithString:stringUrl];

if([[UIApplication sharedApplication] canOpenURL:url]) {
    [[UIApplication sharedApplication] openURL:url];
} else {
    NSLog(@"Cant open %@",url);
}

任何想法？ Facebook应该有“后退按钮”吗？我的网址方案设置正确...

更新 NSDictionary包含所有有效值，我现在不想发布它们，但url，name，store id等都是有效的

更新＃2： 从iOS 9开始，这是由iOS系统自动完成的。

如果您只是使用FB自定义URL链接到FB.APP或Safari，它将不会自动返回到您的应用程序，

applink未连接到FB好友配置文件页面。

替代方法是使用FB IOS SDK并选择并在应用程序中显示远程用户，如下所示:(来自HelloFacebook示例应用程序的代码（随SDK提供）

- (IBAction)pickFriendsClick:(UIButton *)sender {
   FBFriendPickerViewController *friendPickerController = [[FBFriendPickerViewController alloc] init];
     friendPickerController.title = @"Pick Friends";
     [friendPickerController loadData];

   // Use the modal wrapper method to display the picker.
   [friendPickerController presentModallyFromViewController:self animated:YES handler:
    ^(FBViewController *innerSender, BOOL donePressed) {
        if (!donePressed) {
            return;
       }

        NSString *message;

       if (friendPickerController.selection.count == 0) {
            message = @"<No Friends Selected>";
        } else {

            NSMutableString *text = [[NSMutableString alloc] init];

           // we pick up the users from the selection, and create a string that we use to update the text view
            // at the bottom of the display; note that self.selection is a property inherited from our base class
            for (id<FBGraphUser> user in friendPickerController.selection) {
                if ([text length]) {
                   [text appendString:@", "];
                }
               [text appendString:user.name];
           }
           message = text;
       }

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

}

注意 - 示例当前刚刚从FBGraphUser类实例中选择了name属性....

用户将拥有其他属性生日，性别等，只需在SDK中查找头文件或查找FB文档。
