问题描述

我要TP张贴在Facebook上wall.I一些文字与图片有从这是否图形API此code，但我想从后捆绑我的形象，而不是从一个链接作为这个API does.Can谁能告诉我如何上传自己的形象而不是链接[变量的setObject：@http://bit.ly/bFTnqdforKey：@链接];在Facebook上墙。

 的NSMutableDictionary *变量= [的NSMutableDictionary dictionaryWithCapacity：4];[变量的setObject：@这是一个测试消息：postMeFeedButton pressedforKey：@消息];* UIImage的画面= [UIImage的imageNamed：@森林fog.jpg];[变量的setObject：@http://bit.ly/bFTnqdforKey：@链接];
[变量的setObject：@这是旁边的图像粗体副本forKey：@名];
[变量的setObject：@这是旁边的图像纯文本副本只工作，不玩耍，聪明的孩子会变傻。 forKey：@说明];FbGraphResponse * fb_graph_response = [fbGraph doGraphPost：@我/饲料withPostVars：变量];
的NSLog（@postMeFeedButton pressed：％@，fb_graph_response.htmlResponse）;//我们解析JSON
SBJSON *解析器= [[SBJSON的alloc]初始化];
*的NSDictionary = facebook_response [解析objectWithString：fb_graph_response.htmlResponse错误：无];
[解析​​器释放];//让我们保存的ID的Facebook给了我们，所以如果用户presses了删除/我/饲料按钮，我们可以将其删除
self.feedPostId =（的NSString *）[facebook_response objectForKey：@ID];
的NSLog（@feedPostId，％@，feedPostId）;
的NSLog（@现在登录到Facebook和看您的个人资料......）;
 

解决方案

您隐藏图像到数据，并补充说，作为Dictionary.I另一个参数（关键的数据的数据值）在这里给定的样本

  [变量的setObject：为imageData forKey：@数据];
 

其他的更改

 的UIImage *图片= [UIImage的imageNamed：@森林fog.jpg];NSData的*为imageData = UIImageJPEGRe presentation（图10）;
*的NSMutableDictionary PARAMS = [的NSMutableDictionary dictionaryWithObjectsAndKeys：
                               @你的标题消息，@消息，
                               为imageData，@数据
                               零];FbGraphResponse * fb_graph_response = [fbGraph doGraphPost：@我/照片withPostVars：变量];
的NSLog（@postMeFeedButton pressed：％@，fb_graph_response.htmlResponse）;
 

I want tp post some text with image on facebook wall.I have this code from graph api which does that but i want to post my image from bundle and not from a link as this api does.Can anyone tell me how to post your own image rather then the link "[variables setObject:@"http://bit.ly/bFTnqd" forKey:@"link"];" on facebook wall.

NSMutableDictionary *variables = [NSMutableDictionary dictionaryWithCapacity:4];

[variables setObject:@"this is a test message: postMeFeedButtonPressed" forKey:@"message"];

UIImage *picture = [UIImage imageNamed:@"forest fog.jpg"];

[variables setObject:@"http://bit.ly/bFTnqd" forKey:@"link"];
[variables setObject:@"This is the bolded copy next to the image" forKey:@"name"];
[variables setObject:@"This is the plain text copy next to the image.  All work and no play makes Jack a dull boy." forKey:@"description"];



FbGraphResponse *fb_graph_response = [fbGraph doGraphPost:@"me/feed" withPostVars:variables];
NSLog(@"postMeFeedButtonPressed:  %@", fb_graph_response.htmlResponse);

//parse our json
SBJSON *parser = [[SBJSON alloc] init];
NSDictionary *facebook_response = [parser objectWithString:fb_graph_response.htmlResponse error:nil];   
[parser release];

//let's save the 'id' Facebook gives us so we can delete it if the user presses the 'delete /me/feed button'
self.feedPostId = (NSString *)[facebook_response objectForKey:@"id"];
NSLog(@"feedPostId, %@", feedPostId);
NSLog(@"Now log into Facebook and look at your profile...");

解决方案

You covert Image into data and add that as another parameter (Data value for key "data") in the Dictionary.I have given sample here

[variables setObject:imageData forKey:@"data"];

Other Change

UIImage *picture = [UIImage imageNamed:@"forest fog.jpg"];

NSData *imageData = UIImageJPEGRepresentation(picture, 10);


NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               @"your caption message",@"message", 
                               imageData,@"data",
                               nil];

FbGraphResponse *fb_graph_response = [fbGraph doGraphPost:@"me/photos" withPostVars:variables];
NSLog(@"postMeFeedButtonPressed:  %@", fb_graph_response.htmlResponse);
