简单的核心动画UIView的3D变换 [英] Simple Core Animations 3D transform of UIView
本文介绍了简单的核心动画UIView的3D变换的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在尝试使用CA制作简单的部分翻转动画,但我遇到了透视问题。我尝试过:
I'm trying to make simple partly flip animation with CA, but I had a problems with perspective. I tried with:
[UIView animateWithDuration:1.0 animations:^{
self.someView.layer.anchorPoint = CGPointMake(0.5, 0);
self.someView.layer.transform = CATransform3DMakeRotation(M_PI*0.6,1.0,0.0,0.0);
} completion:^(BOOL finished){
// code to be executed when flip is completed
}];
如何获得这个美好的视角?
推荐答案
这样的事情会:
CATransform3D rotationAndPerspectiveTransform = CATransform3DIdentity;
rotationAndPerspectiveTransform.m34 = 1.0 / -1000.0;
rotationAndPerspectiveTransform = CATransform3DRotate(rotationAndPerspectiveTransform, M_PI * 0.6, 1.0f, 0.0f, 0.0f);
[UIView animateWithDuration:1.0 animations:^{
self.someView.layer.anchorPoint = CGPointMake(0.5, 0);
self.someView.layer.transform = rotationAndPerspectiveTransform;
} completion:^(BOOL finished){
// code to be executed when flip is completed
}];
