ios - 从 PHAsset 获取已编辑照片的 URL

Question

我正在尝试使用此代码从 PHAsset 获取照片的 URL。

 let options: PHContentEditingInputRequestOptions = PHContentEditingInputRequestOptions()
 options.canHandleAdjustmentData = {(adjustmeta: PHAdjustmentData) -> Bool in
          return true
  }

  asset.requestContentEditingInput(with: options, completionHandler: { (contentEditingInput, info) in
          guard let url = contentEditingInput?.fullSizeImageURL else {
               observer.onError(PHAssetError.imageRequestFailed)
               return
          }
          /// Using this `url`
  })

大多数照片使用此代码都运行良好。

当我在“相机”应用中拍照并在“照片”应用中旋转照片，然后在我的应用中选择旋转后的照片时，此代码返回原始照片 URL，而不是旋转后的版本。

如何从 PHAsset 获取已编辑照片的本地 URL？

尝试将返回值更改为“false”

If your block returns true, Photos provides the original asset data for editing. Your app uses the adjustment data to alter, add to, or reapply previous edits. (For example, an adjustment data may describe filters applied to a photo. Your app reapplies those filters and allows the user to change filter parameters, add new filters, or remove filters.)

If your block returns false, Photos provides the most recent asset data—the rendered output of all previous edits—for editing.

 let options: PHContentEditingInputRequestOptions = PHContentEditingInputRequestOptions()
 options.canHandleAdjustmentData = {(adjustmeta: PHAdjustmentData) -> Bool in
          return false
  }

  asset.requestContentEditingInput(with: options, completionHandler: { (contentEditingInput, info) in
          guard let url = contentEditingInput?.fullSizeImageURL else {
               observer.onError(PHAssetError.imageRequestFailed)
               return
          }
          /// Using this `url`
  })
