iOS 开发人员：将 UIImage 上传到 facebook 相册时出现问题

请检查我的代码：

在这里，我尝试将屏幕截图上传到 Facebook 相册，但这不起作用

CGImageRef screen = UIGetScreenImage();    
self.image = [UIImage imageWithCGImage:screen];
CGImageRelease(screen);

NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               self.image, @"picture",
                               nil];

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

self.image 没问题，它用于代码的其他部分，一切看起来都不错。如果我为 [uiimage imagenamed@"example.png""] 设置 self.image ，一切都会很好。不同的是，一个 uiimage 存在于内存中，而另一个 uiimage 存在于内存和设备中。

有什么问题吗？

谢谢

please check my code:

Here i'm trying to upload screenshot to facebook album, but that doesnt works

CGImageRef screen = UIGetScreenImage();    
self.image = [UIImage imageWithCGImage:screen];
CGImageRelease(screen);

NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               self.image, @"picture",
                               nil];

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

self.image is ok, it is used in other parts of the code and everything looks nice. if i set up self.image for ex for [uiimage imagenamed@"example.png""] everything works nice. the different is that one uiimage exists on in memory and another both in memory and device.

what can bee wrong?

thanks
