检测相机的光圈何时在 iPhone 上打开 [英] Detecting when camera's iris is open on iPhone

问题描述

对于自定义相机叠加层，我需要找出虹膜何时打开，因为我的叠加层将始终在虹膜关闭时显示(然后以动画方式打开).

For a cutom camera overlay I need to find out, when the iris is opened, because my overlay will allways shown while the iris is close (and then animating to open).

有什么想法吗?

推荐答案

PLCameraViewIrisAnimationDidEndNotification 似乎在iOS5 中不再收到通知.

It seems that PLCameraViewIrisAnimationDidEndNotification no longer gets notified in iOS5.

当虹膜完全打开时，我不知道什么是合适的解决方案，必须有另一个选择，而不是使用 3 秒计时器.

I can't figure out what is a suitable solution when the iris has finished opening, there must another option rather than using a 3 second timer.
