Get the local file path of a PHAsset

Question

I have a photo I want my user to be able to share on Instagram and I need to get the local file directory of the photo.

However I am fetching my images as a PHAsset (not the ALAsset all the other answers seem to cover on this subject).

Looking at the PHAsset documentation I don't see a 'local directory' variable.

Do you know how I can get the path to a photo from the users camera roll using the new ios8 Photo's framework?

Here is my code for loading the last image in the users photo roll

public func loadLastPhotoIntoGalleryIcon()
{
    if(PHPhotoLibrary.authorizationStatus() != PHAuthorizationStatus.Authorized)
    {
        return
    }
    var fetchOptions:PHFetchOptions = PHFetchOptions()
    fetchOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]
    var fetchResult:PHFetchResult = PHAsset.fetchAssetsWithMediaType(PHAssetMediaType.Image, options: fetchOptions)

    var lastAsset:PHAsset = fetchResult.firstObject as PHAsset

    var options:PHImageRequestOptions = PHImageRequestOptions()
    options.version = PHImageRequestOptionsVersion.Current
    PHImageManager.defaultManager().requestImageForAsset(lastAsset, targetSize: _view.getGalleryIconSize(), contentMode: PHImageContentMode.AspectFill, options: options)
    {
        (result, objects) -> Void in
        self._view.setGalleryIcon(result)
    }

}

Use content editing input:

asset.requestContentEditingInput(with: PHContentEditingInputRequestOptions()) { (input, _) in
        let url = input.fullSizeImageURL
}

Make sure that the asset is PHAssetMediaType.Image or otherwise it may crash when unpacking an optional.

func getImagesFromAsset(anAsset: PHAsset) {
    PHImageManager.default().requestImage(for: anAsset, targetSize: CGSize(width: 600, height: 600), contentMode: .aspectFill, options: nil, resultHandler: { (image, info) in
        //resultHandler have info ([AnyHashable: Any])
        print(info!["PHImageFileURLKey"])
        if let img = image {
            self.imgv.image = img
        }
    })
}

this might help paste this in you CellForRowAt method and pass the PHAsset in argument.

but you wont able to access directory since apple privacy policy — Jayraj Vala, Jul 06 '18 at 13:02

PHAsset *asset = YOUR_ASSET;

PHImageManager *manager = [PHImageManager defaultManager];
PHImageRequestOptions *options = [PHImageRequestOptions new];
options.synchronous = YES;
options.deliveryMode = PHImageRequestOptionsDeliveryModeHighQualityFormat;
options.resizeMode = PHImageRequestOptionsResizeModeNone;
options.networkAccessAllowed = NO;

[manager requestImageForAsset:YOUR_ASSET targetSize:PHImageManagerMaximumSize contentMode:PHImageContentModeDefault options:options resultHandler:^(UIImage *resultImage, NSDictionary *info){

    NSURL *filePath = [info valueForKeyPath:@"PHImageFileURLKey"]

}];

asset=PHAsset *asset

[asset requestContentEditingInputWithOptions:[PHContentEditingInputRequestOptions new] completionHandler:^(PHContentEditingInput *contentEditingInput, NSDictionary *info) {
   NSURL *imageURL = contentEditingInput.fullSizeImageURL;
}];

Make sure your PHAsset should be an image type to check this PHAssetMediaType.Image should be true

Yes, you must convert PHAsset to ALAsset, then you can grab the url from ALAsset. Something like this: PHImageManager.defaultManager().requestAVAssetForVideo....

Requests asset information for beginning a content editing session.

- (PHContentEditingInputRequestID)requestContentEditingInputWithOptions:(PHContentEditingInputRequestOptions *)options 
                                                      completionHandler:(void (^)(PHContentEditingInput *contentEditingInput, NSDictionary *info))completionHandler;

The URL to a file that contains the full-sized image data.

@property(readonly, copy) NSURL *fullSizeImageURL;
