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];
其他回答
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。
非常简单
self.navigationController?.view.semanticContentAttribute = .forceRightToLeft
使用私人通话是一个坏主意,因为苹果不再批准这样做的应用程序。 也许你可以试试这个:
//Init Animation
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration: 0.50];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.navigationController.view cache:YES];
//Create ViewController
MyViewController *myVC = [[MyViewController alloc] initWith...];
[self.navigationController pushViewController:myVC animated:NO];
[myVC release];
//Start Animation
[UIView commitAnimations];
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];

如何改变一个基于导航的应用程序的推送和弹出动画…
如果你是iOS开发新手。对于最简单、最常见的动画(如“滑动”或“一个推另一个”),你必须做大量的工作。
1. 你需要一个自定义的uiviewcontrolleranimatedtransiting
You need popStyle boolean - is it popping on, or popping off? You must include transitionDuration (trivial) and the main call, animateTransition You must write the two different animations routines, one for the push, and one for the pop. Inside animateTransition, simply branch on the boolean popStyle to one the two routines The example below does a simple move-over/move-off In your animatePush and animatePop routines. You must get the "from view" and the "to view". (How to do that, is shown in the code example.) and you must addSubview for the new "to" view. and you must call completeTransition at the end of your anime
复制粘贴…
class SimpleOver: NSObject, UIViewControllerAnimatedTransitioning {
var popStyle: Bool = false
func transitionDuration(
using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval {
return 0.20
}
func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
if popStyle {
animatePop(using: transitionContext)
return
}
let fz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.from)!
let tz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.to)!
let f = transitionContext.finalFrame(for: tz)
let fOff = f.offsetBy(dx: f.width, dy: 55)
tz.view.frame = fOff
transitionContext.containerView.insertSubview(tz.view, aboveSubview: fz.view)
UIView.animate(
withDuration: transitionDuration(using: transitionContext),
animations: {
tz.view.frame = f
}, completion: {_ in
transitionContext.completeTransition(true)
})
}
func animatePop(using transitionContext: UIViewControllerContextTransitioning) {
let fz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.from)!
let tz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.to)!
let f = transitionContext.initialFrame(for: fz)
let fOffPop = f.offsetBy(dx: f.width, dy: 55)
transitionContext.containerView.insertSubview(tz.view, belowSubview: fz.view)
UIView.animate(
withDuration: transitionDuration(using: transitionContext),
animations: {
fz.view.frame = fOffPop
}, completion: {_ in
transitionContext.completeTransition(true)
})
}
}
然后……
2. 在视图控制器中使用它。
注意:奇怪的是,你只需要在“first”视图控制器中这样做。(在“下面”的那个。)
对于你放在上面的那个,什么都不做。一件容易的事。
所以你的班级…
class SomeScreen: UIViewController {
}
变得……
class FrontScreen: UIViewController,
UIViewControllerTransitioningDelegate, UINavigationControllerDelegate {
let simpleOver = SimpleOver()
override func viewDidLoad() {
super.viewDidLoad()
navigationController?.delegate = self
}
func navigationController(
_ navigationController: UINavigationController,
animationControllerFor operation: UINavigationController.Operation,
from fromVC: UIViewController,
to toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
simpleOver.popStyle = (operation == .pop)
return simpleOver
}
}
就是这样。
和平常一样,没有变化。推…
let n = UIStoryboard(name: "nextScreenStoryboardName", bundle: nil)
.instantiateViewController(withIdentifier: "nextScreenStoryboardID")
as! NextScreen
navigationController?.pushViewController(n, animated: true)
要弹出它,你可以在下一个屏幕中这样做:
class NextScreen: TotallyOrdinaryUIViewController {
@IBAction func userClickedBackOrDismissOrSomethingLikeThat() {
navigationController?.popViewController(animated: true)
}
}
唷。
