UIImagePickerController - 自定义叠加（Swift）上的重新启动按钮

Question

I am trying to implement a custom cameraOverlayView with a UIImagePickerController . I manage to hide the button and have my own interface , but a custom interface blocks the editing screen with the Preview option and the Retake. I noticed on some older posts adding two Notifications for " _UIImagePickerControllerUserDidCaptureItem ", " _UIImagePickerControllerUserDidRejectItem " and then adding and removing the overlay would fix the issue. But with Swift 3 I cannot seem to find how to access these notifications and the delegate from UIImagePickerController is very limited. Is there another way ?

It seems like you cannot access the "Retake" event , so there is a need to create also a custom "Edit" screen. I have on the same customCameraOverlay , buttons for "Retake" and "Use it". So when the user stops capturing I hide the record and the cancel button and I present the retake and use it options, adding also a preview. So when the user clicks on retake I reverse the buttons again and remove the preview View. Likewise on "Use it" didfinishcapturing is being called
