跳转的动画有很多，全部可以自定义
创建自定义跳转必须遵循的三个步骤:
1、创建一个类,并实现了 UIViewControllerAnimatedTransitioning 协议
2、创建一个类作为 UIViewControllerTransitioningDelegate 过渡代理
3、在模态跳转前修改控制器的 transitioningDelegate 代理为自定义的代理（步骤2的代理类）
核心代码示例
一、创建一个类，并实现了 UIViewControllerAnimatedTransitioning 协议
这个协议主要控制控制器视图的显示的，通过 transitionContext 可以获取到每个视图和控制器，并进行动画的设置

class AnimatedTransitioning: NSObject { var isPresenting: Bool = false}extension AnimatedTransitioning: UIViewControllerAnimatedTransitioning { func transitionDuration(using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval { return 0.5 } func animateTransition(using transitionContext: UIViewControllerContextTransitioning) { let fromView = transitionContext.view(forKey: .from)! let toView = transitionContext.view(forKey: .to)! let containerView = transitionContext.containerView if isPresenting { toView.transform = CGAffineTransform(scaleX: 0, y: 0) containerView.addSubview(toView) } else { containerView.insertSubview(toView, belowSubview: fromView) } UIView.animate(withDuration: 0.5, animations: { if self.isPresenting { toView.transform = CGAffineTransform.identity } else { fromView.transform = CGAffineTransform(scaleX: 0.001, y: 0.001) } }) { (finished) in transitionContext.completeTransition(finished) } }} |
二、创建一个类作为 UIViewControllerTransitioningDelegate 过渡代理
这里设置 presented 和 dismissed 时各自的动画转换类，可以设置为不同的类

class CustomTransitioningDelegate: NSObject, UIViewControllerTransitioningDelegate { func animationController(forPresented presented: UIViewController, presenting: UIViewController, source: UIViewController) -> UIViewControllerAnimatedTransitioning? { let at = AnimatedTransitioning() at.isPresenting = true return at } func animationController(forDismissed dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? { let at = AnimatedTransitioning() at.isPresenting = false return at }} |
三、在模态跳转前修改控制器的 transitioningDelegate 代理为自定义的代理
注意：代理不能为局部变量

class ViewController: UIViewController { // 必须保存为实例变量 var ctDelegate = CustomTransitioningDelegate() override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) { let vc = TempViewController() vc.transitioningDelegate = ctDelegate self.present(vc, animated: true, completion: nil) }} |
以上这篇iOS 控制器自定义动画跳转方法(模态跳转)就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持服务器之家。
