将 uiviewcontroller 推到另一个 viewcontroller 并使用从上到下的动画

Question

在我的项目中有一个功能，当用户在顶部栏上滑动时，一个屏幕会出现从上到下的动画

有两个视图控制器 oneviewcontroller.m

- (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];
}

但这并没有给出从上到下的动画

我想实现导航推 := 顶部 - 底部弹出：=底部 - 顶部

请帮帮我谢谢

Answer 1

您可以像下面这样从上到下推送视图控制器：

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];
}

使用下面的代码从底部到顶部弹出视图控制器：

- (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)
  }

将 uiviewcontroller 推到另一个 viewcontroller 并使用从上到下的动画

push uiviewcontroller to another viewcontroller with animation from Top - bottom

transition

uinavigationcontroller

uianimation
