想要在拍照时让取景器中心出现一个十字，在通过UIImagePickerController的cameraOverlayView属性添加十字的视图时，如何定位才能放到取景器的中心呢？很明显取景器视图中心位置和屏幕的中心位置并没有重合。而且UIImagePickerController的视图结构是私有的，没办法得到任何关于取景器视图范围的信息。
UIImagePickerController
cameraOverlayView
thx

I don’t have any specific practice myself, sorry. What the questioner means is that the center point cannot be obtained?
Since I didn’t write it myself, I tried to quote the article, hoping it can help the questioner.
The following article introduces:这个代码就可以实现拍照功能了，如果把注释掉的代码加上就可以添加overlayview，比如十字准星，条形码扫描框之类的
