Save UIImage to Photo Library Instead of Camera Roll

Question

I know how to save an image using standard API calls to the camera roll. I also know that devices without a camera get saved to the Photo Library.

For devices with a camera, how do I save a UIImage to the Photo Library INSTEAD of the camera roll?

Answer 1

您应该尝试通过IOS SDK提供此方法，

UIImageWriteToSavedPhotosAlbum(myImage, nil, nil, nil );

Answer 2

我知道如何做到这一点的唯一方法是使用UIImageWriteToSavedPhotosAlbum，快速路由是将nil传递给除UIImage参数之外的所有内容。

UIImageWriteToSavedPhotosAlbum(UIImage *image, id completionTarget, SEL completionSelector, void *contextInfo);

Answer 3

The photo library is just a placeholder that shows all the pics on your phone, including the camera roll. So, if you deleted a pic from the camera, it would be gone on the photo library. The one in the photo library is not a duplicate; it's more like a shortcut. Makes perfect sense. It's like a "favorites" folder. It sources it's info from the main folder.
