当前回答
只使用:
ViewController *viewController = [[ViewController alloc] init];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController];
navController.navigationBarHidden = YES;
[self presentViewController:navController animated:YES completion: nil];
[viewController release];
[navController release];

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)
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;
}
只使用:
ViewController *viewController = [[ViewController alloc] init];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController];
navController.navigationBarHidden = YES;
[self presentViewController:navController animated:YES completion: nil];
[viewController release];
[navController release];
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)
})
流行:
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)
有UINavigationControllerDelegate和uiviewcontrolleranimatedtransiating你可以改变任何你想要的动画。
例如,这是VC的垂直流行动画:
@objc class PopAnimator: NSObject, UIViewControllerAnimatedTransitioning {
func transitionDuration(transitionContext: UIViewControllerContextTransitioning?) -> NSTimeInterval {
return 0.5
}
func animateTransition(transitionContext: UIViewControllerContextTransitioning) {
let fromViewController = transitionContext.viewControllerForKey(UITransitionContextFromViewControllerKey)!
let toViewController = transitionContext.viewControllerForKey(UITransitionContextToViewControllerKey)!
let containerView = transitionContext.containerView()
let bounds = UIScreen.mainScreen().bounds
containerView!.insertSubview(toViewController.view, belowSubview: fromViewController.view)
toViewController.view.alpha = 0.5
let finalFrameForVC = fromViewController.view.frame
UIView.animateWithDuration(transitionDuration(transitionContext), animations: {
fromViewController.view.frame = CGRectOffset(finalFrameForVC, 0, bounds.height)
toViewController.view.alpha = 1.0
}, completion: {
finished in
transitionContext.completeTransition(!transitionContext.transitionWasCancelled())
})
}
}
然后
func navigationController(navigationController: UINavigationController, animationControllerForOperation operation: UINavigationControllerOperation, fromViewController fromVC: UIViewController, toViewController toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
if operation == .Pop {
return PopAnimator()
}
return nil;
}
