在Three20中使用CATransition？

Question

我想在TTNavigator中实现CATransitions,我知道方法openURL可以采用UIViewAnimationTransition,但只能让我翻转和卷曲动画,但是使用CATransition我可以访问另外8个,其中kCATransitionFromRight,kCATransitionFromLeft,kCATransitionFromTop,kCATransitionFromBottom是那些我特意追问.

使用UINavigationController会使用类似代码的东西来让我更好地控制动画:

    CATransition *transition = [CATransition animation];
    transition.duration = 0.5f;
    transition.timingFunction = [CAMediaTimingFunction
    functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionPush;
    [self.navigationController.view.layer addAnimation:transition
    forKey:nil];

但是,此代码不适用于TTNavigator.有谁知道如何使用我自己的自定义动画来使用TTNavigator？或者如果我在代码中做错了什么？

Answer 1

事实证明我回答了我自己的问题,但是我没有使用最后一行代码来设置navigationController上的动画,而是试图设置过渡到URLAction.一旦我将该行重新放入并注释掉了URLAction转换代码,它似乎正常工作!

    // create the URLAction
TTURLAction* urlAction;
urlAction = [TTURLAction actionWithURLPath:@"tt://Images"]; 
[urlAction applyAnimated:YES];

    // create the CATransition and set it to the navigation controller
CATransition *transition = [CATransition animation];
transition.duration = 0.5f;
transition.timingFunction = [CAMediaTimingFunction
functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
[self.navigationController.view.layer addAnimation:transition
forKey:nil]; 

    // tell the navigator to run the action
[[TTNavigator navigator] openURLAction:urlAction];

希望这有助于将来的其他人!
