使用“pushViewController”在 UITabController 中的选项卡之间切换时的动画

Question

我在尝试使 UITabBarViewController 执行与 UINavigationController 执行 PushViewController 时相同的动画时遇到问题。

- (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController {

UIViewController *currentVC = [tabBarController selectedViewController];
if (currentVC == viewController) 
    return NO;

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1];
UIModalTransitionStyle transition = UIModalTransitionStyleFlipHorizontal;
[UIView setAnimationTransition:transition forView:tabBarController.view cache:YES];
[currentVC viewWillAppear:YES];
[viewController viewWillDisappear:YES];
[viewController viewDidDisappear:YES];
[currentVC viewDidAppear:YES];
[UIView commitAnimations];
return YES;}

下面的代码在切换选项卡时执行动画：

- (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController {

UIViewController *currentVC = [tabBarController selectedViewController];
if (currentVC == viewController) 
    return NO;

[UIView beginAnimations:@"View Flip" context:nil];
[UIView setAnimationDuration:1.25];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];

[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:tabBarController.view cache:YES];
[currentVC viewWillAppear:YES];
[viewController viewWillDisappear:YES];
[viewController viewDidDisappear:YES];
[currentVC viewDidAppear:YES];
[UIView commitAnimations];

return YES;}

如何修改上面的代码以执行从右侧滑动的动画，类似于将 viewController 推入导航控制器？

看看这个链接： http ://haveacafe.wordpress.com/2009/04/06/animated-transition- Between-tabbars-view-on-iphone/

这个想法是，你需要使用选项卡bar 控制器的委托方法并使用特定的动画类 CATransition （因为您在视图之间“转换”）。查看 CATransition 文档，了解动画的类型/子类型。您可能需要一种带有 left 或 right 子类型的推送类型。
