UITabBar 导航和presentModalViewController

发布于 2024-12-25 04:21:00 字数 346 浏览 1 评论 0原文

我有基于 UITabBar 的导航，并且希望标签栏始终位于其他窗口之上。在一个控制器中，我有打开其他控制器的方法，但是当我使用此 UITabBar 时，它会消失。我还应该做什么？

ThirdView*third =[[ThirdView alloc] initWithNibName:nil bundle:nil];
third.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self.tabBarController presentModalViewController:third animated:YES];
[third release];

您应该将 UINavigationController 用于 UITabBarController 的选项卡。然后，要呈现一个新的 UIViewController，您需要将新的它推送到 UINavigationController 的堆栈上。你可以这样做：

[self.navigationController PushViewController:yourController
动画：是]；

如果你想要模态效果，你可以这样做：

#import <QuartzCore/QuartzCore.h>

 CATransition* transition = [CATransition animation]; transition.duration = 0.4f;
 transition.type = kCATransitionMoveIn;
 transition.subtype = kCATransitionFromTop;
 [self.navigationController.view.layer addAnimation:transition
                                                 forKey:kCATransition]
 [self.navigationController pushViewController:v animated:NO];

You should use UINavigationControllers for the tabs of your UITabBarController. Then to present a new UIViewController you want to push new it onto the stack of your UINavigationController. You can do this like so:

[self.navigationController pushViewController:yourController
animated:YES];

If you want the modal effect, you could do something like this:

#import <QuartzCore/QuartzCore.h>

 CATransition* transition = [CATransition animation]; transition.duration = 0.4f;
 transition.type = kCATransitionMoveIn;
 transition.subtype = kCATransitionFromTop;
 [self.navigationController.view.layer addAnimation:transition
                                                 forKey:kCATransition]
 [self.navigationController pushViewController:v animated:NO];
