Using the code bellow you will get path like:assets-library://asset/asset.JPG?id=79450962-C0FD-484C-808B-83E045F40972&ext=JPGwhen your picking image from photo album. This path is valid. It contains the asset ID and asset type.
使用下面的代码，您将获得如下路径：assets-library://asset/asset.JPG?id=79450962-C0FD-484C-808B-83E045F40972&ext=JPG当您从相册中选择图像时。此路径有效。它包含资产 ID 和资产类型。
// Firstly get the picked image's file URL.
NSURL *imageFileURL = [info objectForKey:UIImagePickerControllerReferenceURL];
// Then get the file name.
NSString *imageName = [imageFileURL lastPathComponent];
NSLog(@"image name is %@", imageName);
If you want to get image user picked again using the path you get using UIImagePickerController.(Here maybe you want to save the path so that you can read that image back without asking user to pick that image again) You will need the ALAssetsLibraryotherwise you don't need it.
如果您想使用您使用的路径再次选择图像用户UIImagePickerController。（这里也许您想保存路径，以便您可以在不要求用户再次选择该图像的情况下读取该图像），ALAssetsLibrary否则您将不需要'不需要。
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
__block UIImage *returnValue = nil;
[library assetForURL:imageFileURL resultBlock:^(ALAsset *asset) {
returnValue = [UIImage imageWithCGImage:[[asset defaultRepresentation] fullResolutionImage]];
} failureBlock:^(NSError *error) {
NSLog(@"error : %@", error);
}];

Take a look at the UIImagePickerControllerDelegate Protocol. The string UIImagePickerControllerReferenceURLcontains an URL of your file. You could use it to construct the filename from it.
看看 UIImagePickerControllerDelegate 协议。字符串UIImagePickerControllerReferenceURL包含文件的 URL。您可以使用它来构造文件名。
Other than that there seems to be no built-in way to get the file name from an UIImage or UIImageView object.
除此之外，似乎没有从 UIImage 或 UIImageView 对象获取文件名的内置方法。

You can get the file name using below code:
您可以使用以下代码获取文件名：
NSURL *assetURL = [imageDic objectForKey:UIImagePickerControllerReferenceURL];
__block NSString *originalFileName = nil;
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library assetForURL:assetURL resultBlock:^(ALAsset *asset){
originalFileName = [[asset defaultRepresentation] filename];
}
originalFileName give the original file name of resource.
originalFileName 给出资源的原始文件名。
