Facebook SDK iOS：将帖子添加到带有图像的提要

Question

我已经知道如何将帖子添加到我的用户供稿中，但目前它需要使用图片 URL：

// The action links to be shown with the post in the feed
NSArray* actionLinks = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys:
                                                  self.title,@"name",self.url,@"link", nil], nil];
NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks];

// Dialog parameters
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               self.title, @"name",
                               @"Created using My App.", @"caption",
                               @"Check out the thing I just uploaded!", @"description",
                               self.url, @"link",
                               @"http://www.facebookmobileweb.com/hackbook/img/facebook_icon_large.png", @"picture",
                               actionLinksStr, @"actions",
                               nil];

[facebook dialog:@"feed" andParams:params andDelegate:self];

我想上传UIImage。我看到有些人谈论为此使用graph api。我将如何做到这一点并且仍然能够使用标题、标题和消息？

用这两行替换你的四行代码：

NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:YourUIImage, @"source",@"caption description",@"message",  nil];

[facebook requestWithGraphPath:[NSString stringWithFormat:@"/me/photos?access_token=%@", facebook.accessToken] andParams:params andHttpMethod:@"POST" andDelegate:self];

和你的 UIImage 的“YourUIImage”。 希望我回答了你的问题！
