iPhone 截图

我一直在使用 UIGetScreenImage() 来获取 UIImagePickerController 的屏幕截图。基本上我使用相机覆盖层，然后当我拍摄屏幕截图时，我会看到相机预览显示的图像以及我的覆盖层，这正是我所需要的。

现在 UIGetScreenImage() 已被禁止，我还没有找到方法来做到这一点。它只为相机显示黑色。

编辑：我的所有其他视图都显示得非常好，只是不是实际的相机预览。有什么想法吗？？！？！？

这是我目前正在使用的代码。


UIGraphicsBeginImageContext(picker.view.bounds.size);
[picker.view.layer renderInContext:UIGraphicsGetCurrentContext()];
CGContextDrawImage(context, bounds, camView.CGImage);
UIImage* screenImage = UIGraphicsGetImageFromCurrentImageContext();
UIImageWriteToSavedPhotosAlbum(screenImage, nil, nil, nil); 
UIGraphicsEndImageContext();

有什么想法如何获得叠加层+相机图像吗？

谢谢！

I've been using UIGetScreenImage() to get a screenshot of a UIImagePickerController. Basically I use the camera overlay and then when I take the screenshot, I have the image that the camera preview had been showing and my overlay on there too, which is exactly what I need.

Now UIGetScreenImage() has been banned, I've not been able to find a way to do this. It just shows black for the camera.

Edit: all of my other views are showing absolutely fine, just not the actual camera preview. Any ideas??!?!?

Here's the code I am using at the moment.


UIGraphicsBeginImageContext(picker.view.bounds.size);
[picker.view.layer renderInContext:UIGraphicsGetCurrentContext()];
CGContextDrawImage(context, bounds, camView.CGImage);
UIImage* screenImage = UIGraphicsGetImageFromCurrentImageContext();
UIImageWriteToSavedPhotosAlbum(screenImage, nil, nil, nil); 
UIGraphicsEndImageContext();

Any ideas how I can get the overlay + the camera image?

Thanks!

这与你的略有不同。

CGRect screenRect = [[UIScreen mainScreen] bounds];
        UIGraphicsBeginImageContext(screenRect.size);
        [self.layer renderInContext:UIGraphicsGetCurrentContext()];
        UIImage *sShot = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();
        UIImageWriteToSavedPhotosAlbum (sShot, nil, nil, nil);

那有用吗？

如果没有，您可能想尝试在 iphonedevsdk.com 上询问，因为他们专注于 iPhone 的所有产品。

This is slightly different than yours.

CGRect screenRect = [[UIScreen mainScreen] bounds];
        UIGraphicsBeginImageContext(screenRect.size);
        [self.layer renderInContext:UIGraphicsGetCurrentContext()];
        UIImage *sShot = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();
        UIImageWriteToSavedPhotosAlbum (sShot, nil, nil, nil);

Does that work?

If not, you might want to try asking over at iphonedevsdk.com since they specialize in all things iPhone.
