ios - 从网络下载图像时如何找到“UIImagePickerControllerOriginalImage”和“UIImagePickerControllerReferenceURL”

Question

我想得到UIImagePickerControllerOriginalImage，UIImagePickerControllerReferenceURL当我下载图像并将其保存到相册时..

谁能建议找到这两个参数的正确方法？

如果我使用方法“

[library writeImageToSavedPhotosAlbum:[viewImage CGImage] orientation:(ALAssetOrientation)[viewImage imageOrientation] completionBlock:^(NSURL *assetURL, NSError *error)

我会得到“UIImagePickerControllerReferenceURL”，如果我使用

UIImageWriteToSavedPhotosAlbum([UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:self.imageURL]]], testOriginalImage, @selector(image:didFinishSavingWithError:contextInfo:), nil)

我会得到“UIImagePickerControllerOriginalImage”

怎么做才能两者兼得？

Answer 1

如果你打电话：

[library writeImageToSavedPhotosAlbum:[viewImage CGImage] orientation:(ALAssetOrientation)[viewImage imageOrientation] completionBlock:^(NSURL *assetURL, NSError *error)

然后你得到/拥有两者。是assetURL和UIImagePickerControllerReferenceURL与viewImage相同UIImagePickerControllerOriginalImage。
