1.設(shè)置轉(zhuǎn)場(chǎng)代理

myView.transitioningDelegate = self

2.設(shè)置轉(zhuǎn)場(chǎng)動(dòng)畫(huà)樣式

my.modalPresentationStyle = .Custom

3.彈出菜單

presentCiewController(myView, animated: true, comletion: nil)

extension 實(shí)現(xiàn)代理方法

func animationControllerForPresentedController(presented:UIViewController, presentingController presenting: UIViewController, sourceController source: UIViewController) -> UIViewControllerAnimatedTransitioning? {

return MyPresentationController(presentedViewController:? presented,presentingViewController: presenting) //自定義的presentationController類(lèi)

}

自定義presentationController

class MyPresentationController : UIPresentationController
{

?override init(presentedViewController: UIViewController, presentingViewController: UIViewController) {

? super.init(presentedViewController: presentedViewController, presentingViewController: presentingController)

?}

//用于布局轉(zhuǎn)場(chǎng)動(dòng)畫(huà)彈出的視圖

override func containerViewWillLayoutSubviews(){

// containerView 容器視圖

// presentedView() 拿到彈出的視圖

presentedView()?.frame = CGRect(x: 100, y: 45, width: 200, height: 200)

}
