379. The iOS Apprentice 4 - StoreSearch 7 - Landscape-1

from iOSDevLog Hosted by iOSDevLog

iOS 7 自定义视图控制器转场的 API 基本上都是以协议的方式提供的,这也使其可以非常灵活的使用,因为你可以很简单地将它们插入到你的类中。最主要的五个组件如下: 动画控制器 (Animation Controllers) 遵从 UIViewControllerAnimatedTransitioning 协议,并且负责实际执行动画。 交互控制器 (Interaction Controllers) 通过遵从 UIViewControllerInteractiveTransitioning 协议来控制可交互式的转场。 转场代理 (Transitioning Delegates) 根据不同的转场类型方便的提供需要的动画控制器和交互控制器。 转场上下文 (Transitioning Contexts) 定义了转场时需要的元数据,比如在转场过程中所参与的视图控制器和视图的相关属性。 转场上下文对象遵从 UIViewControllerContextTransitioning 协议,并且这是由系统负责生成和提供的。 转场协调器(Transition Coordinators) 可以在运行转场动画时,并行的运行其他动画。 转场协调器遵从 UIViewControllerTransitionCoordinator 协议。
