Question

    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                 @"parth kausik", @"name", 
                                 imageview.image, @"picture",   
                                 nil];

  [facebook requestWithGraphPath:@"me/photos" andParams:params andHttpMethod:@"POST" andDelegate:self];

你好，这些代码不起作用。它没有调用请求代理而没有上传任何图片。你有任何想法..

Answer 1

添加社交框架，然后添加导入类，并添加以下代码

 SLComposeViewController *facebookPostVC =[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook ];
[facebookPostVC setInitialText:@"iPhone Application"];
[facebookPostVC addURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@",link]]];
[facebookPostVC addImage:[UIImage imageNamed:@"Default.png"]];
[self presentViewController:facebookPostVC animated:YES completion:nil];

注意：这适用于Xcode 4.5

只需编写参数并将图像设置为以下函数中的描述：

- (void) uploadImageWithName : (NSString*)name
{
    NSString *img = [NSString stringWithFormat:@"%@.png",name];
    UIImage *uploadImage = [UIImage imageNamed:img];//you can get the image on other ways also like imageView.image

    NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   [fb accessToken], 
                                   @"access_token",nil];

    [params setObject:uploadImage forKey:@"source"];

    [fb requestWithGraphPath:@"me/photos"
                             andParams: params
                         andHttpMethod: @"POST"
                           andDelegate:self];

}
