Answer 1

NSURL *photoURL = ...; 
    NSURL *videoURL = ...; 

    [[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{ 
      PHAssetCreationRequest *request = [PHAssetCreationRequest creationRequestForAsset]; 


      //These types should be inferred from your files 

      //PHAssetResourceCreationOptions *photoOptions = [[PHAssetResourceCreationOptions alloc] init]; 
      //photoOptions.uniformTypeIdentifier = @"public.jpeg"; 

      //PHAssetResourceCreationOptions *videoOptions = [[PHAssetResourceCreationOptions alloc] init]; 
      //videoOptions.uniformTypeIdentifier = @"com.apple.quicktime-movie"; 

      [request addResourceWithType:PHAssetResourceTypePhoto fileURL:photoURL options:nil /*photoOptions*/]; 
      [request addResourceWithType:PHAssetResourceTypePairedVideo fileURL:videoURL options:nil /*videoOptions*/]; 

     } completionHandler:^(BOOL success, NSError * _Nullable error) { 
      NSLog(@"success? %d, error: %@",success,error); 
     }];

斯威夫特3：

PHPhotoLibrary.shared().performChanges({ 

     let request = PHAssetCreationRequest.forAsset() 

     request.addResource(with: .photo, fileURL: photoURL, options: nil) 
     request.addResource(with: .pairedVideo, fileURL: videoURL, options: nil) 

    }) { (success, error) in 

     print(success) 
     print(error?.localizedDescription ?? "error") 
    }
