camera - ios 10 对未渲染的 View 进行快照会生成空快照

Question

this question ask again但我没有找到 ios 10

if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.camera)
 {
            self.imagePicker.delegate = self
            self.imagePicker.sourceType = UIImagePickerControllerSourceType.camera;
            self.imagePicker.allowsEditing = false
            self.imagePicker.cameraCaptureMode = .photo
            //self.imagePicker.modalPresentationStyle = UIModalPresentationStyle.overCurrentContext
            self.present(self.imagePicker, animated: true, completion: nil)
            self.imagePicked.isUserInteractionEnabled = true

 }
else
 {
            print("No Camera")
 }

Snapshotting a view that has not been rendered results in an empty snapshot.Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates.

当我旋转相机并拍摄时，会发生此错误。

自助解决方案像魅力一样为我工作 :-) 希望对所有人都有帮助

DispatchQueue.global(qos: .userInitiated).async
{
     self.present(self.imagePicker, animated: true, completion: nil)

}
