UIImagePicker cameraOverlayView出现在Retake屏幕上 [英] UIImagePicker cameraOverlayView appears on Retake screen

问题描述

我正在努力解决问题。
我正在捕捉一个视频，我把一个带有UIImage的UIImageView作为UIImagePicker CameraOverLay。
因此，当用户启动相机以捕获视频时，他可以在相机上看到叠加。当用户停止捕获并且正在移动到UIImagePicker的取消或重新启动屏幕时，cameraOverlayView仍然可见。

I am struggling with a problem. I am capturing a video, and i had put an UIImageView with an UIImage in it as the UIImagePicker CameraOverLay. So when the user starts the camera in order to capture a video, he can see an overlay on the camera. When the user stops capturing, and is being moved to the "cancel or Retake" screen of the UIImagePicker, the cameraOverlayView is still visible.

关于如何在重拍或取消屏幕中不显示叠加层的任何想法？

any ideas on how to not display the overlay in the "retake or cancel" screen?

推荐答案

通过注册NSNotificationCenter解决，并听取@_ UIImagePickerControllerUserDidCaptureItem和@_ UIImagePickerControllerUserDidRejectItem。

Solved by signing up to NSNotificationCenter, and listening to @"_UIImagePickerControllerUserDidCaptureItem" and @"_UIImagePickerControllerUserDidRejectItem".
