but when i try to save image using URL then URL is nil.

 `NSData *pngData =[NSData dataWithContentsOfURL:urlA options:NSDataReadingMapped error:nil];`

You can get the imageURL from PHContentEditingInput:

Swift:

asset.requestContentEditingInput(with: PHContentEditingInputRequestOptions()) { (eidtingInput, info) in
  if let input = eidtingInput, let imgURL = input.fullSizeImageURL {
     // imgURL 
  }
}

Objective-C:

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