如何使用图形 API 将图像发布到 Facebook 墙

Question

我想在 Facebook 墙上发布一些带有图像的文字。我有来自图形 API 的代码，它可以执行此操作，但我想从捆绑包中发布我的图像，而不是像此 API 那样从链接中发布图像。谁能告诉我如何发布你自己的图片而不是链接

"[variables setObject:@"http://bit . ly/bFTnqd" forKey:@"link"];" 

在 Facebook 墙上。

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...");

Answer 1

您将图像隐藏为数据并将其添加为字典中的另一个参数（键“数据”的数据值）。我在这里给出了示例

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

其他变更

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);

以下代码应该可以解决您的问题...

    FBStreamDialog *dialog = [[[FBStreamDialog alloc] init] autorelease];
    dialog.attachment = [NSString stringWithFormat:@"{\"name\":\"Photo uploaded.\",\"description\":\"\",\"media\":[{\"type\":\"image\",\"src\":\"\",\"href\":\"%@/\"}]}",PhotoSourceURL];
    [dialog show];

让我知道，它对你有用吗...
