ios - iOS 7 在本机相机应用程序中创建翻转动画，如旋转动画

Question

我正在与 AVFoundation 一起使用自定义相机创建 iOS 应用程序。我的问题是相机旋转，改变前后相机的预览层，如何像原生相机应用一样制作动画。翻转动画？

谢谢，

尝试这个：

CATransition *animation = [CATransition animation];
animation.duration = .5f;
animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
animation.type = @"oglFlip";
if (captureDevice.position == AVCaptureDevicePositionFront) {
    animation.subtype = kCATransitionFromRight;
}
else if(captureDevice.position == AVCaptureDevicePositionBack){
    animation.subtype = kCATransitionFromLeft;
}
[capturePreviewLayer addAnimation:animation forKey:nil];
