虽然这里所有的答案都很棒,而且大多数工作得很好,但有一个稍微简单一点的方法可以达到同样的效果……
推动:
NextViewController *nextViewController = [[NextViewController alloc] init];
// Shift the view to take the status bar into account
CGRect frame = nextViewController.view.frame;
frame.origin.y -= 20;
frame.size.height += 20;
nextViewController.view.frame = frame;
[UIView transitionFromView:self.navigationController.topViewController.view toView:nextViewController.view duration:0.5 options:UIViewAnimationOptionTransitionFlipFromRight completion:^(BOOL finished) {
[self.navigationController pushViewController:nextViewController animated:NO];
}];
流行:
int numViewControllers = self.navigationController.viewControllers.count;
UIView *nextView = [[self.navigationController.viewControllers objectAtIndex:numViewControllers - 2] view];
[UIView transitionFromView:self.navigationController.topViewController.view toView:nextView duration:0.5 options:UIViewAnimationOptionTransitionFlipFromLeft completion:^(BOOL finished) {
[self.navigationController popViewControllerAnimated:NO];
}];}

基于jordanperry为swift 4更新的答案
用于推送UIViewController
let yourVC = self.storyboard?.instantiateViewController(withIdentifier: "yourViewController") as! yourViewController
UIView.animate(withDuration: 0.75, animations: {() -> Void in
UIView.setAnimationCurve(.easeInOut)
self.navigationController?.pushViewController(terms, animated: true)
UIView.setAnimationTransition(.flipFromRight, for: (self.navigationController?.view)!, cache: false)
})
为流行
UIView.animate(withDuration: 0.75, animations: {() -> Void in
UIView.setAnimationCurve(.easeInOut)
UIView.setAnimationTransition(.flipFromLeft, for: (self.navigationController?.view)!, cache: false)
})
navigationController?.popViewController(animated: false)
@Luca Davanzo的答案在Swift 4.2
public extension UINavigationController {
/**
Pop current view controller to previous view controller.
- parameter type: transition animation type.
- parameter duration: transition animation duration.
*/
func pop(transitionType type: CATransitionType = .fade, duration: CFTimeInterval = 0.3) {
self.addTransition(transitionType: type, duration: duration)
self.popViewController(animated: false)
}
/**
Push a new view controller on the view controllers's stack.
- parameter vc: view controller to push.
- parameter type: transition animation type.
- parameter duration: transition animation duration.
*/
func push(viewController vc: UIViewController, transitionType type: CATransitionType = .fade, duration: CFTimeInterval = 0.3) {
self.addTransition(transitionType: type, duration: duration)
self.pushViewController(vc, animated: false)
}
private func addTransition(transitionType type: CATransitionType = .fade, duration: CFTimeInterval = 0.3) {
let transition = CATransition()
transition.duration = duration
transition.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeInEaseOut)
transition.type = type
self.view.layer.add(transition, forKey: nil)
}
}
以下是我如何在Swift中做同样的事情:
推动:
UIView.animateWithDuration(0.75, animations: { () -> Void in
UIView.setAnimationCurve(UIViewAnimationCurve.EaseInOut)
self.navigationController!.pushViewController(nextView, animated: false)
UIView.setAnimationTransition(UIViewAnimationTransition.FlipFromRight, forView: self.navigationController!.view!, cache: false)
})

实际上,我对上面的一些回答做了一些不同的处理——但由于我是Swift开发的新手,这可能是不对的。我重写了viewWillDisappear:animated:,并在那里添加了弹出代码:
UIView.animateWithDuration(0.75, animations: { () -> Void in
UIView.setAnimationCurve(UIViewAnimationCurve.EaseInOut)
UIView.setAnimationTransition(UIViewAnimationTransition.FlipFromLeft, forView: self.navigationController!.view, cache: false)
})
super.viewWillDisappear(animated)
从示例应用程序中,可以看到这种变化。 https://github.com/mpospese/MPFoldTransition/
#pragma mark - UINavigationController(MPFoldTransition)
@implementation UINavigationController(MPFoldTransition)
//- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
- (void)pushViewController:(UIViewController *)viewController foldStyle:(MPFoldStyle)style
{
[MPFoldTransition transitionFromViewController:[self visibleViewController]
toViewController:viewController
duration:[MPFoldTransition defaultDuration]
style:style
completion:^(BOOL finished) {
[self pushViewController:viewController animated:NO];
}
];
}
- (UIViewController *)popViewControllerWithFoldStyle:(MPFoldStyle)style
{
UIViewController *toController = [[self viewControllers] objectAtIndex:[[self viewControllers] count] - 2];
[MPFoldTransition transitionFromViewController:[self visibleViewController]
toViewController:toController
duration:[MPFoldTransition defaultDuration]
style:style
completion:^(BOOL finished) {
[self popViewControllerAnimated:NO];
}
];
return toController;
}
我不知道有什么方法可以公开更改过渡动画。
如果“后退”按钮不是必需的,你应该使用模态视图控制器来实现“push from bottom”/“flip”/“fade”/(≥3.2)“页面卷曲”过渡。
在私有端,方法-pushViewController:animated:调用未记录的方法-pushViewController:transition:forceImmediate:,因此,例如,如果你想要一个从左到右的翻转转换,你可以使用
[navCtrler pushViewController:ctrler transition:10 forceImmediate:NO];
但是,您不能以这种方式更改“pop”过渡。
