我正试图在像这样的视图控制器中获得3d翻转动画
https://github.com/nicklockwood/CubeController
对于动画..基于反向值我设置时钟方向或反时钟方向
这是我用于动画的代码..
class CusNavAnimController : NSObject, UIViewControllerAnimatedTransitioning {
var reverse: Bool = false
func transitionDuration(transitionContext: UIViewControllerContextTransitioning?) -> NSTimeInterval {
return 0.25
}
func animateTransition(transitionContext: UIViewControllerContextTransitioning) {
let containerView = transitionContext.containerView()
let toViewController = transitionContext.viewControllerForKey(UITransitionContextToViewControllerKey)!
let fromViewController = transitionContext.viewControllerForKey(UITransitionContextFromViewControllerKey)!
let toView = toViewController.view
let fromView = fromViewController.view
//
toView.frame = UIScreen.mainScreen().bounds
fromView.frame = UIScreen.mainScreen().bounds
let direction: CGFloat = reverse ? -1 : 1
let const: CGFloat = -0.005
toView.layer.anchorPoint = CGPointMake(direction == 1 ? 0 : 1, 0.5)
fromView.layer.anchorPoint = CGPointMake(direction == 1 ? 1 : 0, 0.5)
var viewFromTransform: CATransform3D = CATransform3DMakeRotation(direction * CGFloat(M_PI_2), 0.0, 1.0, 0.0)
var viewToTransform: CATransform3D = CATransform3DMakeRotation(-direction * CGFloat(M_PI_2), 0.0, 1.0, 0.0)
viewFromTransform.m34 = const
viewToTransform.m34 = const
containerView!.transform = CGAffineTransformMakeTranslation(direction * containerView!.frame.size.width / 2.0, 0)
toView.layer.transform = viewToTransform
containerView!.addSubview(toView)
UIView.animateWithDuration(transitionDuration(transitionContext), animations: {
containerView!.transform = CGAffineTransformMakeTranslation(-direction * containerView!.frame.size.width / 2.0, 0)
fromView.layer.transform = viewFromTransform
toView.layer.transform = CATransform3DIdentity
}, completion: {
finished in
containerView!.transform = CGAffineTransformIdentity
fromView.layer.transform = CATransform3DIdentity
toView.layer.transform = CATransform3DIdentity
fromView.layer.anchorPoint = CGPointMake(0.5, 0.5)
toView.layer.anchorPoint = CGPointMake(0.5, 0.5)
if (transitionContext.transitionWasCancelled()) {
toView.removeFromSuperview()
} else {
fromView.removeFromSuperview()
}
transitionContext.completeTransition(!transitionContext.transitionWasCancelled())
})
}}
我正在获取动画，但它与提供的git hub链接不同。 对于我的代码.. fromview稍微回过头来看看从那一点来到前面..任何人都可以建议我改变
