如何在Facebook上发布对话文本的本地图片 [英] How to post local image with dialog text in facebook

问题描述

  NSMutableDictionary * params = [NSMutableDictionary dictionaryWithObjectsAndKeys：
 @https://developers.facebook.com/docs/reference/dialogs/，@link，
 @http://fbrell.com/f8.jpg，@picture，
 @Facebook对话框，@名称，
 @参考文档，@caption，
 @使用对话框与用户交互，@description，
 nil]; 
 
 AppDelegate * delegate =（AppDelegate *）[[UIApplication sharedApplication] delegate]; 
 [[委托Facebook]对话框：@feed
 andParams：params 
 andDelegate：self]; 
  

现在我想以同样的方式从本地图像上传图片

喜欢

  profImg = [UIImage imageNamed：[e-mail]]; 
 NSData * data = [NSData dataWithData：UIImagePNGRepresentation（profImg）]; 
  

我使用了数据，@图片，在字典中，但它给我错误

是否有任何其他方式上传本地/画廊/资源图像与对话框box + comment area？

我搜索过，但每次发现只有url图像可以提供对话框

我已经使用Hackgraph教程来发布这个帖子。

注意：我没有使用Sharekit或任何其他API，我只使用Graph API

解决方案

最后经过大量的研究，我得到了Facebook的例子，从这里。您必须进行修改，因为当前示例保留静态图像。

I have upload images with url image successful on this way

NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               @"https://developers.facebook.com/docs/reference/dialogs/", @"link",
                               @"http://fbrell.com/f8.jpg", @"picture",
                               @"Facebook Dialogs", @"name",
                               @"Reference Documentation", @"caption",
                               @"Using Dialogs to interact with users.", @"description",
                               nil];

AppDelegate *delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
[[delegate facebook] dialog:@"feed"
           andParams:params
         andDelegate:self];

Now i want to upload image from a local image in same way

like

    profImg = [UIImage imageNamed:[e-mail]"];
    NSData *data = [NSData dataWithData:UIImagePNGRepresentation(profImg)];

i have used data, @"picture", in dictionary but it's give me error

is it any other way to upload local/Gallery/resource image with dialog box + comment area ?

I have searched but every time found that only url image can feed the dialog box

I have used Hackgraph tutorial for this posting.

Note: I am not using Sharekit or any other API i have used only Graph API

解决方案

Finally after lots of research I get the example of Facebook. Download the example from here. You have to make modification because currently example hold static image.
