问题描述
我有一个应用程序，我必须在Facebook的墙上发布图像。
现在问题是我使用GraphAPI的脸书，我必须传递照片的链接，但我在我的iPhone上有照片，而不是在任何服务器上。
那么如何在没有URL的图像和其他参数的情况下张贴墙壁？

Now problem is i used GraphAPI facebook and i have to pass link of photo but i have photo in my iPhone and not on any server.
So how do i post wall with image and other parameters without URL of image?
推荐答案
您可以使用NSURLConnection ASIHttpRequest库从url下载图像。
You may use NSURLConnection ASIHttpRequest library for downloading the images from a url.
You will have to do the following:
1. Create a NSUrlConnection and implement the delegate methods
2. Pass the url in your request and you will get the data in -(void)connectionDidFinishLoading: (NSURLConnection *)connection
3. You can then create a UIImage from this data using UIImage *image = [[UIImage alloc] initWithData:activeDownloadData];
