Question

我的应用程序是使用UINavigationController为所有导航设置的。我想使用模态转换在应用程序中呈现特定的视图控制器。问题是我希望将新VC嵌入导航控制器中，但只有一个视图需要使用模态动画而不是推动。

如何在UINavigationController中的单个视图控制器上实现此模态动画/转换？

请记住，在此模式动画发生后，该页面上的按钮将继续按照标准UINavigationController推送动画工作。

Answer 1

ITviewViewController *vc = [[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:@"vc"];
vc.modalPresentationStyle = UIModalPresentationFullScreen;
vc.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentViewController:vc animated:YES completion:Nil];

用视图控制器名称替换伪代码。

Answer 2

使用iOS7，可以使用新的自定义转换API。您可以在此处找到更多信息：http://www.objc.io/issue-5/view-controller-transitions.html

您可以创建动画控制器（交互式或其他），并使用导航栏代理的相应方法传递它。在动画控制器中，使用UIView动画API执行自定义动画。在您的情况下，动画应该从底部到前进动画执行幻灯片，并从一个地方滑到另一个底部以进行反向动画。如果您支持交互式动画，您甚至可以控制动画相对于手指幻灯片的曲线。

Answer 3

默认情况下，模态视图为全屏。您需要更改演示文稿样式以显示navigationBar

编辑：这仅适用于iPad。对于iPhone，您可以使用MZformsheet或Kentnguyen获取半模式行为

MyModalViewController *targetController = [[[MyModalViewController alloc] init] autorelease]; 

targetController.modalPresentationStyle = UIModalPresentationFormSheet;

targetController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; //transition shouldn't matter 

[self presentModalViewController:targetController animated:YES];


targetController.view.superview.frame = CGRectMake(0,44/*navigation bar's height*/,height, width);//it's important to do this after 
// use full screen height and width here

targetController.view.superview.center = self.view.center;

Answer 4

使用此行not presentModelViewController

[self presentViewController:vc animated:YES completion:Nil];

也许这样的东西对你有用（自我是UINavigationController）：

- (void)verticalPushViewController:(UIViewController *)controller
{
    [UIApplication sharedApplication].keyWindow.backgroundColor = [UIColor colorWithWhite:1 alpha:0.9];
    CATransition* transition = [CATransition animation];
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut];
    transition.duration = 0.3;
    transition.type = kCATransitionMoveIn;
    transition.subtype = kCATransitionFromTop;
    [self.view.layer addAnimation:transition forKey:kCATransition];
    [self pushViewController:controller animated:NO];
}

- (UIViewController *)verticalPopViewController
{
    [UIApplication sharedApplication].keyWindow.backgroundColor = [UIColor colorWithWhite:1 alpha:0.9];
    CATransition* transition = [CATransition animation];
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut];
    transition.duration = 0.3;
    transition.type = kCATransitionPush;
    transition.subtype = kCATransitionFromBottom;
    [self.view.layer addAnimation:transition forKey:kCATransition];
    return [self popViewControllerAnimated:NO];
}

最简单的方法。

呈现

LaunchImageViewController *launchView = [self.storyboard instantiateViewControllerWithIdentifier:@"launchImage"];
[[UIApplication sharedApplication].keyWindow addSubview:launchView.view];

关闭。我在里面调用了这个（LaunchImageViewController）。

[self.view removeFromSuperview];

iOS 7在UINavigationController中提供模态视图？
