FBConnect facebook.stream.publish与NSDictionary问题 [英] FBConnect facebook.stream.publish with NSDictionary problems

问题描述

我有这个代码，直到现在才能发送Facebook请求。

I have this code that can't send a Facebook request until now.

NSDictionary *firstDict = [NSDictionary dictionaryWithObjectsAndKeys:
    @"image", @"Type",
    @"http://mysite.com/image.jpg", @"src",
    @"http://mysite.com/page.html", @"href",
    nil];
NSDictionary *secondDict = [NSDictionary dictionaryWithObjectsAndKeys:
    @"image", @"Type",
    @"http://mysite.com/image.jpg", @"src",
    @"http://mysite.com/page.html", @"href",
    nil];
NSArray *mediaArray = [[NSArray alloc] initWithObjects:firstDict, secondDict, nil];

NSArray *keys = [NSArray arrayWithObjects:@"name", @"description", @"href", @"media", nil];
NSArray *objects = [NSArray arrayWithObjects:
    [NSString stringWithString:@"MyTitle"],
    [NSString stringWithString:@"My caption"],
    [NSString stringWithString:@"http://mysite.com/page.html"], mediaArray, nil];

NSDictionary *attachment = [NSDictionary dictionaryWithObjects:objects forKeys:keys];
[[FBRequest requestWithDelegate:self] call:@"facebook.stream.publish" params:attachment];

我拿这个样本： http://forum.developers.facebook.com/viewtopic.php?pid=145965

但是每次我运行它，控制台显示如下：

But every time I run it, the console shows the following:

 {
     "api_key" = adc8d70987098sdc;
     "call_id" = 23456767;
     description = "Any user's description";
     format = XML;
     href = "http://mysite.com/page.html";
     media =     (
                 {
             Type = image;
             href = "http://mysite.com/page.html";
             src = "http://mysite.com/image.jpg";
         },
                 {
             Type = image;
             href = "http://mysite.com/page.html";
             src = "http://mysite.com/image.jpg";
         }
     );
     method = "Facebook.streamPublish";
     name = aName;
     "session_key" = "d0f98bfs89b7fg7v";
     sig = 89v0d9fv879fgv;
     ss = 1;
     v = "1.0"; }

它显示数组的括号，而不是括号，是否正常？

It shows parentheses for array instead brackets, is that normal?.

然后它显示错误：

*** -[NSCFArray dataUsingEncoding:]: unrecognized selector sent to instance
     0x12fcb0 2009-10-30 13:54:27.758 GeoPixr[307:207]
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason:
*** -[NSCFArray dataUsingEncoding:]: unrecognized selector sent to instance 0x12fcb0

< 。

The [session resume] call returns TRUE.

提前感谢。

推荐答案

一个发送数组字典的方法，但有另一个类为我工作：

I couldn't find a way to send the dictionary with an array but there's another class that works for me:

FBStreamDialog

这会在发送信息之前打开一个对话框，通过代理方法可以了解更改。

Which brings up a dialog before it sends the information and it's delegate methods lets you know about changes.
