我正在尝试实现类似的目标:
但是在导航 Controller 中有一个 push segue。有办法实现吗?
最佳答案
我几个月前就做过了。
1.自定义您的过渡。例如,这是 Push(因此是 Pop):
class BWFlipTransionPush: NSObject, UIViewControllerAnimatedTransitioning {
func transitionDuration(transitionContext: UIViewControllerContextTransitioning?) -> NSTimeInterval {
return 0.5
}
func animateTransition(transitionContext: UIViewControllerContextTransitioning) {
let fromVC = transitionContext.viewControllerForKey(UITransitionContextFromViewControllerKey)
let toVC = transitionContext.viewControllerForKey(UITransitionContextToViewControllerKey)! // as! UBPasswordLoginViewController
let container = transitionContext.containerView()
container!.addSubview(toVC.view)
container!.bringSubviewToFront(fromVC!.view)
//改变m34
var transfrom = CATransform3DIdentity
transfrom.m34 = -0.002
container!.layer.sublayerTransform = transfrom
//设置anrchPoint 和 position
let initalFrame = transitionContext.initialFrameForViewController(fromVC!)
toVC.view.frame = initalFrame
fromVC!.view.frame = initalFrame
toVC.view.layer.transform = CATransform3DMakeRotation(CGFloat(M_PI_2), 0, 1, 0)
//动画
UIView.animateWithDuration(transitionDuration(transitionContext), delay: 0, options: UIViewAnimationOptions.CurveEaseOut, animations: { () -> Void in
fromVC!.view.layer.transform = CATransform3DMakeRotation(CGFloat(-M_PI_2), 0, 1, 0)
}) { (finished: Bool) -> Void in
container?.bringSubviewToFront(toVC.view)
UIView.animateWithDuration(self.transitionDuration(transitionContext), delay: 0, options: UIViewAnimationOptions.CurveEaseOut, animations: { () -> Void in
toVC.view.layer.transform = CATransform3DIdentity
}) { (finished: Bool) -> Void in
fromVC!.view.layer.transform = CATransform3DIdentity
transitionContext.completeTransition(!transitionContext.transitionWasCancelled())
}
}
}
}
2.像这样为您的导航 Controller 设置委托(delegate):
override func viewDidLoad() {
super.viewDidLoad()
navigationController?.delegate = self
}
3.实现委托(delegate)函数:
func navigationController(navigationController: UINavigationController, animationControllerForOperation operation: UINavigationControllerOperation, fromViewController fromVC: UIViewController, toViewController toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
switch operation {
case .Pop:
return nil // you should return customized pop
case .Push:
return BWFlipTransionPush()
default:
return nil
}
}
更新
这是翻转弹出:
class BWFlipTransionPop: NSObject, UIViewControllerAnimatedTransitioning {
func transitionDuration(transitionContext: UIViewControllerContextTransitioning?) -> NSTimeInterval {
return 0.5
}
func animateTransition(transitionContext: UIViewControllerContextTransitioning) {
let fromVC = transitionContext.viewControllerForKey(UITransitionContextFromViewControllerKey)! // as! UBPasswordLoginViewController
let toVC = transitionContext.viewControllerForKey(UITransitionContextToViewControllerKey)
let container = transitionContext.containerView()
container!.addSubview(toVC!.view)
//改变m34
var transfrom = CATransform3DIdentity
transfrom.m34 = -0.002
container!.layer.sublayerTransform = transfrom
//设置anrchPoint 和 position
let initalFrame = transitionContext.initialFrameForViewController(fromVC)
toVC!.view.frame = initalFrame
toVC!.view.layer.transform = CATransform3DMakeRotation(CGFloat(-M_PI_2), 0, 1, 0)
//动画
UIView.animateWithDuration(transitionDuration(transitionContext), delay: 0, options: UIViewAnimationOptions.CurveEaseOut, animations: { () -> Void in
fromVC.view.layer.transform = CATransform3DMakeRotation(CGFloat(M_PI_2), 0, 1, 0)
}) { (finished: Bool) -> Void in
container?.bringSubviewToFront(toVC!.view)
UIView.animateWithDuration(self.transitionDuration(transitionContext), delay: 0, options: UIViewAnimationOptions.CurveEaseOut, animations: { () -> Void in
toVC!.view.layer.transform = CATransform3DIdentity
}) { (finished: Bool) -> Void in
fromVC.view.layer.transform = CATransform3DIdentity
transitionContext.completeTransition(!transitionContext.transitionWasCancelled())
}
}
}
}

总的来说,我对ruby还比较陌生,我正在为我正在创建的对象编写一些rspec测试用例。许多测试用例都非常基础,我只是想确保正确填充和返回值。我想知道是否有办法使用循环结构来执行此操作。不必为我要测试的每个方法都设置一个assertEquals。例如:describeitem,"TestingtheItem"doit"willhaveanullvaluetostart"doitem=Item.new#HereIcoulddotheitem.name.shouldbe_nil#thenIcoulddoitem.category.shouldbe_nilendend但我想要一些方法来使用
出于纯粹的兴趣,我很好奇如何按顺序创建PI,而不是在过程结果之后生成数字,而是让数字在过程本身生成时显示。如果是这种情况,那么数字可以自行产生,我可以对以前看到的数字实现垃圾收集,从而创建一个无限系列。结果只是在Pi系列之后每秒生成一个数字。这是我通过互联网筛选的结果:这是流行的计算机友好算法,类机器算法:defarccot(x,unity)xpow=unity/xn=1sign=1sum=0loopdoterm=xpow/nbreakifterm==0sum+=sign*(xpow/n)xpow/=x*xn+=2sign=-signendsumenddefcalc_pi(digits
