iOS8 Photos Framework: How to get the name(or filename) of a PHAsset?

Question

Im trying to get the image name using PHAssets. But I couldn't find metadata for filename or any method to get the image name. Is there a different way to get the file name?

Answer 1

I know the question has already been answered, but I figured I would provide another option:

extension PHAsset {     var originalFilename: String? {         var fileName: String?          if #available(iOS 9.0, *) {             let resources = PHAssetResource.assetResources(for: self)             if let resource = resources.first {                 fileName = resource.originalFilename             }         }          if fileName == nil {             /// This is an undocumented workaround that works as of iOS 9.1             fileName = self.value(forKey: "filename") as? String         }          return fileName     } }

If you want to get the image name (for example name of last photo in Photos) like IMG_XXX.JPG, 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"];      }                                                 }]; } 

Hope it helps.

In Swift the code will look like this

PHImageManager.defaultManager().requestImageDataForAsset(asset, options: PHImageRequestOptions(), resultHandler: {     (imagedata, dataUTI, orientation, info) in     if info!.keys.contains(NSString(string: "PHImageFileURLKey"))     {         let path = info![NSString(string: "PHImageFileURLKey")] as! NSURL     } }) 

Swift 4:

    let fetchResult = PHAsset.fetchAssets(with: .image, options: nil)     if fetchResult.count > 0 {         if let asset = fetchResult.firstObject {             let date = asset.creationDate ?? Date()             print("Creation date: \(date)")             PHImageManager.default().requestImageData(for: asset, options: PHImageRequestOptions(),                 resultHandler: { (imagedata, dataUTI, orientation, info) in                     if let info = info {                         if info.keys.contains(NSString(string: "PHImageFileURLKey")) {                             if let path = info[NSString(string: "PHImageFileURLKey")] as? NSURL {                                 print(path)                             }                         }                     }             })         }     }
