Replacing ALAssertLibrary to get the filename - ios

Question

Im using the following code to access filename of the image that I gotta upload. I need both filename alongside the file path and size.
ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *imageAsset)
{
ALAssetRepresentation *imageRep = [imageAsset defaultRepresentation];
NSLog(#"[imageRep filename] : %#", [imageRep filename]);
[_imageNameArray addObject:[imageRep filename]];
};
[_uploadTbleView reloadData];
ALAssetsLibrary* assetslibrary = [[ALAssetsLibrary alloc] init];
[assetslibrary assetForURL:refURL resultBlock:resultblock failureBlock:nil];
The problem that Im facing is,
Xcode throws a warning message that ALAssetsLibraryAssetForURLResultBlock is deprecated. How can I replace the above code to get the filename ?
I tried using PHAsset but every time when Im selecting the file, it has got the same file name called asset.jpg for all image files.

You can try this:
PHAsset *asset = nil;
PHFetchOptions *fetchOptions = [[PHFetchOptions alloc] init];
fetchOptions.sortDescriptors = #[[NSSortDescriptor sortDescriptorWithKey:#"creationDate" ascending:YES]];
PHFetchResult *fetchResult = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeImage options:fetchOptions];
if (fetchResult != nil && fetchResult.count > 0) {
// get last photo from Photos
asset = [fetchResult lastObject];
}
if (asset) {
// get photo info from this asset
PHImageRequestOptions * imageRequestOptions = [[PHImageRequestOptions alloc] init];
imageRequestOptions.synchronous = YES;
[[PHImageManager defaultManager]
requestImageDataForAsset:asset
options:imageRequestOptions
resultHandler:^(NSData *imageData, NSString *dataUTI,
UIImageOrientation orientation,
NSDictionary *info)
{
NSLog(#"info = %#", info);
if ([info objectForKey:#"PHImageFileURLKey"]) {
// path looks like this -
// file:///var/mobile/Media/DCIM/###APPLE/IMG_####.JPG
NSURL *path = [info objectForKey:#"PHImageFileURLKey"];
}
}];
}
