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;
}

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];
}];}
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];
I found a mildly recursive way to do this that works for my purposes. I have an instance variable BOOL that I use to block the normal popping animation and substitute my own non-animated pop message. The variable is initially set to NO. When the back button is tapped, the delegate method sets it to YES and sends a new non-animated pop message to the nav bar, thereby calling the same delegate method again, this time with the variable set to YES. With the variable is set to YES, the delegate method sets it to NO and returns YES to allow the non-animated pop occur. After the second delegate call returns, we end up back in the first one, where NO is returned, blocking the original animated pop! It's actually not as messy as it sounds. My shouldPopItem method looks like this:
- (BOOL)navigationBar:(UINavigationBar *)navigationBar shouldPopItem:(UINavigationItem *)item
{
if ([[navigationBar items] indexOfObject:item] == 1)
{
[expandedStack restack];
}
if (!progPop)
{
progPop = YES;
[navBar popNavigationItemAnimated:NO];
return NO;
}
else
{
progPop = NO;
return YES;
}
}
对我有用。
记住,在Swift中,扩展绝对是你的朋友!
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: String = kCATransitionFade, duration: CFTimeInterval = 0.3) {
self.addTransition(transitionType: type, duration: duration)
self.popViewControllerAnimated(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: String = kCATransitionFade, duration: CFTimeInterval = 0.3) {
self.addTransition(transitionType: type, duration: duration)
self.pushViewController(vc, animated: false)
}
private func addTransition(transitionType type: String = kCATransitionFade, duration: CFTimeInterval = 0.3) {
let transition = CATransition()
transition.duration = duration
transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
transition.type = type
self.view.layer.addAnimation(transition, forKey: nil)
}
}
非常简单
self.navigationController?.view.semanticContentAttribute = .forceRightToLeft
