如何自定义相机屏幕边框？
我想启动具有自定义框架的相机，以便我应该能够在同一视图中显示 UIsearchBar ，并且在触摸 UISearchBar 时我需要关闭相机，但是 < code>UIsearchBar 应该可见。所以我想停止相机将整个iPhone屏幕作为一个框架。 所以我想知道如何自定义相机屏幕？
I want to lauch camera with customised frame so that I should be able to show UIsearchBar in the same View and on touching the UISearchBar I need to close the camera, but the UIsearchBar should be visible. So I want to stop the camera to take the full iPhone screen as a frame.
So I want to know how to customise the Camera Screen?

你基本上有两个选择。最简单的一种是使用UIImagePickerController 的cameraOverlayView 属性。这允许您在相机顶部显示视图：

如果您需要更复杂的东西，您可以使用 AVFoundation 框架。简而言之，它将允许您在视图中的任何位置显示相机流：

You basically have two options. The easiest one is to use the cameraOverlayView property of the UIImagePickerController. This allows you to display a view on top of the camera:

If you need something more elaborate you can use the AVFoundation framework. In short, it will allow you to display the camera stream anywhere you want in a view:
