从PHAsset获取经过编辑的照片的URL

问题描述

我正在尝试使用此代码从PHAsset获取照片的URL.

I'm trying to get a photo's URL from a PHAsset using this code.

 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`
  })

大多数照片与此代码配合良好.

Most of the photos are working well with this code.

当我在相机"应用中拍摄照片并在照片"应用中旋转照片，然后在我的应用中选择旋转的照片时，此代码将返回原始照片URL，而不是旋转的版本.

When I take a photo in the Camera app and rotate the photo in the Photos app, then select the rotated photo in my app, this code returns the original photo URL -- not the rotated version.

如何从PHAsset获取经过编辑的照片的本地URL?

How can I get the edited photo's local URL from PHAsset?

推荐答案

尝试将返回值更改为" false "

Try changing your return to "false"

如果您的区块返回false，则照片"会提供最新的资产 数据-以前所有编辑的渲染输出-进行编辑.

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`
  })
