使用自上而下的动画将uiviewcontroller推送到另一个视图控制器
使用自上而下的动画将uiviewcontroller推送到另一个视图控制器
提问于 2016-04-14 18:35:05
在我的项目中有功能，当用户在顶部栏上滑动一个屏幕将出现从上到下的动画
有两个视图控制器，一个视图控制器。
- (void)swipe
{
listViewController *list_obj=[[listViewController alloc] initWithNibName:@"listViewController" bundle:NULL];
UIViewAnimationTransition trans = UIViewAnimationTransitionCurlUp;
[UIView beginAnimations: nil context: nil];
[UIView setAnimationTransition: trans forView: [self.view window] cache: YES];
[self.navigationController pushViewController:list_obj animated:YES];
[UIView commitAnimations];
}但这并不能提供自上而下的动画
我想实现从Push :=顶部到底部的导航
请帮帮我谢谢

您可以从上到下推送视图控制器，如下所示：
Obj-C：
- (void) pushVC:(UIViewController )dstVC {
CATransition *transition = [CATransition animation];
transition.duration = 0.5;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromTop;
[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
[self.navigationController pushViewController:dstVC animated:NO];
}使用下面的代码从下到上弹出视图控制器：
- (void) popVC {
CATransition *transition = [CATransition animation];
transition.duration = 0.5;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionFade;
transition.subtype = kCATransitionFromBottom;
[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
[self.navigationController popViewControllerAnimated:NO];
}Swift 3：
func open() {
let settingsVC = SettingsVC()
let transition = CATransition()
transition.duration = 0.5
transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
transition.type = kCATransitionPush
transition.subtype = kCATransitionFromTop
navigationController?.view.layer.add(transition, forKey: kCATransition)
navigationController?.pushViewController(settingsVC, animated: false)
}
func close() {
let transition = CATransition()
transition.duration = 0.5
transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
transition.type = kCATransitionFade
transition.subtype = kCATransitionFromBottom
navigationController?.view.layer.add(transition, forKey:kCATransition)
let _ = navigationController?.popViewController(animated: false)
