iOS：发布在所选FB朋友的墙上 [英] iOS: Post on wall of Selected FB Friends

问题描述

场景： 我想将帖子分享到只有选定的朋友的墙上。

先决条件：
在FB朋友的整个列表中，只选择必要的朋友并创建一个数组

尝试的步骤：

强制>使用 FBWebDialogs 并调用方法 +（void）presentFeedDialogModallyWithSession：（FBSession *）会话参数：（NSDictionary *）参数处理程序：（FBWebDialogHandler）处理程序;

在参数字典中，设置to的值。

收件人只有一个，工作完全正常。

试用版2： 使用 FBDialogs 并调用 +（FBAppCall *）presentShareDialogWithParams：（FBShareDialogParams *）params clientState：（NSDictionary *）clientState处理程序：（FBDialogAppCallCompletionHandler）handler; p>

在 FBShareDialogParams 中，设置好友数组。
工程正常。但只有在安装了Facebook应用程序时才可以使用。其他没有工作。

...

有些可以帮我解决这个问题：

1. 分享到多个朋友的墙上。


2. 应该使用或不使用
   Facebook应用程序安装在手机上。

谢谢

解决方案

您必须执行以下操作：

  FBShareDialogParams * p = [[FBShareDialogParams alloc] init]; 
 p.friends = friendIdsArray;`
 p.link = url; 
 
 //检查FB应用程序是否安装并可以使用此方法
 if（[FBDialogs canPresentShareDialogWithParams：p]）{
 [FBDialogs presentShareDialogWithParams：p 
 clientState ：nil 
处理程序：^（FBAppCall *调用，
 NSDictionary *结果，
 NSError *错误）{
 //做一些错误检查
} 
 //回退到本质上是一个webview 
 else {
 //逗号分隔的Facebook的IDs 
 NSDictionary * params = [NSDictionary dictionaryWithObjectsAndKeys：@1234,5678，@to ，nil]; 
 NSString * message = @我喜欢Objective-C; 
 [FBWebDialogs presentRequestsDialogModallyWithSession：[FBSession activeSession] 
消息：消息
标题：nil 
参数：params 
处理程序：^（FBWebDialogResult结果，
 NSURL * resultURL，NSError * error）{
 //做一些错误检查
} 
  

这是我使用的，我发现唯一的问题是，发送请求时可以包含的Facebook ID数量似乎有一些未知的限制。它有所不同，取决于我找不到文件的因素。我认为FB正试图阻止人们滥用/滥用垃圾邮件，理由很好....

Scenario: I would want to share the post to the wall of only selected friends.

Prerequisites followed: Out of the entire list of FB Friends, select only the necessary friends and create an Array

Steps Tried:

Trial 1: Use FBWebDialogs and call method + (void)presentFeedDialogModallyWithSession:(FBSession *)session parameters:(NSDictionary *)parameters handler:(FBWebDialogHandler)handler;

In the Parameters dictionary, set value for "to".

Works perfectly fine when the recipient is only one. Cannot share if the recipient is more than one.

Trial 2: Use FBDialogs and call + (FBAppCall *)presentShareDialogWithParams:(FBShareDialogParams *)params clientState:(NSDictionary *)clientState handler:(FBDialogAppCallCompletionHandler)handler;

In the FBShareDialogParams, set the Array of Friends. works fine. But works only when the Facebook App is installed. Else doesnt work.

...

Can some please help me solve this problem:

1. Share on wall of multiple Friends.
2. Should work with or without the Facebook App being installed on phone.

Thanks

解决方案

You must do something like:

FBShareDialogParams *p = [[FBShareDialogParams alloc] init];
p.friends = friendIdsArray;`
p.link = url;

//check if the FB app is installed and can use this method
if ([FBDialogs canPresentShareDialogWithParams:p]) {
    [FBDialogs presentShareDialogWithParams:p 
                                clientState:nil 
                                    handler:^(FBAppCall *call,
                                        NSDictionary *results,
                                               NSError *error) {
            //do some error checking
}
// fallback to what is essentially a webview
else {
    // string of comma separated Facebook Ids
    NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:@"1234,5678", @"to", nil];
    NSString *message = @"I love Objective-C";
    [FBWebDialogs presentRequestsDialogModallyWithSession:[FBSession activeSession]
                                                  message:message 
                                                    title:nil 
                                               parameters:params
                                                  handler:^(FBWebDialogResult result,
                                                                    NSURL *resultURL, NSError *error) {
              // do some error checking 
    } 

This is what I use, the only problem I'm finding is that there appears to be some unknown limit to the number of Facebook Ids you can include when sending out a request. It varies and depends on factors I can't find documented. I think FB is trying to keep people from abusing/spamming people, for good reason....
