使用UIPercentDrivenInteractiveTransition自定义导航栏的交互式动画 我的简书
只需要将viewController加入导航器，然后正常push和pop
let nav = LSNavigationController.init(rootViewController: ViewController.init())
self.window?.rootViewController = nav
let second = secondViewController.init()
self.navigationController?.pushViewController(second, animated: true)
1、初始化动画管理器
fileprivate lazy var animation :LSAnimationManage = LSAnimationManage()
2、实现管理器的代理
// MARK:-弹出图片协议
protocol LSAnimationStartDelegate :class {
///present前获取动画起始坐标
func ls_getStartFrame(_ indexPath:IndexPath) -> CGRect
/// present前获取动画结束坐标
func ls_getEndFrame(_ indexPath:IndexPath) -> CGRect
/// present前获取动画截图（动画利用截图实现）
func ls_getStartImageView(_ indexPath:IndexPath) -> UIImageView
}
3、构建图片数组（元素是： LSPhotoItem 类型）
for i in 0..<28 {
let item : LSPhotoItem = LSPhotoItem()
item.q_pic_url = "\(i%14)"+".jpg"
item.z_pic_url = "\(i%14)"+".jpg"
item.isUrl = false //用来区分网络图片还是本地图片
self.photos.append(item)
}
4、点击图片展示
///跳转浏览图片
let photoVc = LSPhotoController()
// modal的转场类型
// photoVc.modalTransitionStyle = .FlipHorizontal
// 设置转场动画代理
photoVc.transitioningDelegate = animation;
photoVc.modalPresentationStyle = .custom
photoVc.phoths = self.photos
photoVc.indexPath = indexPath
// 设置代理
animation.endDelegate = photoVc
animation.startDelegate = self
present(photoVc, animated:true, completion: nil)
