CGImageCreate：无效的图像alphaInfo：kCGImageAlphaNone应该是kCGImageAlphaNoneSkipLast

如何解决CGImageCreate：无效的图像alphaInfo：kCGImageAlphaNone应该是kCGImageAlphaNoneSkipLast

我正在尝试将UIVIew捕获为图像，然后可以对其进行操作。我有可在Xcode 11.7 / simulator（运行iOS 13.7）中运行的代码，但抛出此错误：

CGImageCreate：无效的图像alphaInfo：kCGImageAlphaNone。应该是kCGImageAlphaNoneskipLast

在实际设备上运行会导致崩溃。

有什么主意，我该如何在不使用Alpha的情况下创建此图像，或者在事后将其删除？

extension UIView  {
    // render the view within the view's bounds,then capture it as image
  func asImage() -> UIImage {
    let renderer = UIGraphicsImageRenderer(bounds: bounds)
    return renderer.image(actions: { rendererContext in
        layer.render(in: rendererContext.cgContext)
    })
  }
}

通过以下代码调用它：

@IBAction func reactionListButtonTapped(_ sender: UIButton) {
  guard let reactionVC = storyboard?.instantiateViewController(withIdentifier: "ReactionViewController")
    as? ReactionViewController else {
      
    assertionFailure("No view controller ID ReactionViewController in storyboard")
    return
  }

  // take a snapshot of current view and set it as backingImage
  reactionVC.backingImage = self.view.asImage()

  self.present(reactionVC,animated: false,completion: nil)
}

感谢您的帮助。
