Summarize the strange interaction between reader and live broadcast: review ShuangDi Technology

With reference didi/DoKit

Scene one :

When developing a reader project , There's a problem ,

You need to pop up a menu when you click on the green area , Therefore, a View,

However , When sliding in this area , The sliding gesture is blocked by the green area , The gesture cannot be passed to the following UIPageViewController Of View On

describe

Above the reader , Shake and shake , Come out with a green menu

You can order , You can also drag

Dragging is below UIPageViewController Things about .

The gesture is blocked by the green view , Need a passthrough

Ideas :

Put the green view hitTest View , Give it to the reader you are reading , That page

Drag the green view like this , You can also slide

class GreenView: UIView{


    override func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {

        var afterThat = next

        while afterThat != nil{

            if let tmp = afterThat as? ViewController{

                if let target = tmp.pagedController.viewControllers?.first{

                    return target.view

                }

            }

            else{

                afterThat = afterThat?.next

            }

        }

        return nil

    }

}

At the same time, we should capture the click event of the green view ,

By reading the view controller of the page , To catch

class ContentCtrl: UIViewController {

    override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {

        if let touch = touches.first, greenFrame.contains(touch.location(in: view)){

            NotificationCenter.default.post(name: .hitGreen, object: nil)

        }

    }

}

scene 2:

Users are in the live broadcast room , Eat the melon

Here comes an important message , It must be handled by the user ,

The user exits the live broadcast room , Also show ,

At the same time, it does not affect the user to send gifts to the anchor

Pictured above , The user sees the message , You can also use a slide reader

（ In the message area , Sliding is invalid ）

The idea must be window,

Disengage the controller , Can also show

Achieve one , Create a new window

class MsgWindow: UIWindow {


    init() {

        let originX: CGFloat = 50

        let width = UIScreen.main.bounds.width - originX * 2
        //  Fixed window size 

        super.init(frame: CGRect(x: originX, y: 100, width: width, height: 150))

        clipsToBounds = true

        layer.cornerRadius = 8

        backgroundColor = UIColor.cyan
        //  promote  zIndex

        windowLevel = UIWindow.Level.statusBar + 100

        isHidden = true


    }


    func show(){
         //  Necessary configuration for presentation 

        if windowScene == nil, let scene = UIApplication.shared.connectedScenes.first as? UIWindowScene{

            windowScene = scene

        }

        isHidden = false

    }

}

Realization 2, Use the old window and View

class MsgView: UIView {

    init() {

        let originX: CGFloat = 50

        let width = UIScreen.main.bounds.width - originX * 2

        super.init(frame: CGRect(x: originX, y: 100, width: width, height: 150))

        clipsToBounds = true

        layer.cornerRadius = 8

        backgroundColor = UIColor.cyan
        //  Set up  z Index

        layer.zPosition = CGFloat.infinity

        isHidden = true

        

    }

    

    func show(){
        //  find  key window, 
        //  Put the view , Add to 

        let scenes = UIApplication.shared.connectedScenes

        for sce in scenes{

            if let windowScene = sce as? UIWindowScene, windowScene.activationState == .foregroundActive , let win = windowScene.windows.first{

                isHidden = false

                win.addSubview(self)

                return
            }
        }
    }
}

scene 3,

Users are in the live broadcast room , Eat the melon

Here comes an important message , It must be handled by the user ,

The user exits the live broadcast room , Also show ,

At the same time, it does not affect the user to send gifts to the anchor

This message , For a long

（ In the message area , Sliding effective ）

Ideas , Extended scenario 2 Of the 2 Kind of implementation

In a word , Limited the response range ,

Rewrote func point(inside

class MsgView: UIView {
    

    let rect : CGRect = {

        let originX: CGFloat = 50

        let width = UIScreen.main.bounds.width - originX * 2

        return CGRect(x: originX, y: 100, width: width, height: 400)

    }()


    let btnRect = CGRect(x: 10, y: 10, width: 50, height: 50)



    init() {

        

        super.init(frame: rect)

        clipsToBounds = true

        layer.cornerRadius = 8

        backgroundColor = UIColor.clear

        layer.zPosition = CGFloat.infinity

        isHidden = true

        

        let bg = UIView(frame: CGRect(origin: .zero, size: rect.size))

        bg.backgroundColor = UIColor.cyan

        bg.alpha = 0.5

        addSubview(bg)

        

        

        let btn = UIButton(frame: btnRect)

        btn.backgroundColor = UIColor.red

        btn.layer.cornerRadius = 8

        btn.backgroundColor = UIColor.white

        addSubview(btn)

        btn.addTarget(self, action: #selector(hide), for: .touchUpInside)

    }

    

    @objc func hide(){

        isHidden = true

    }

    

    override func point(inside point: CGPoint, with event: UIEvent?) -> Bool {

        return btnRect.contains(point)

    }


}

Why this message , no need scroll View ?

ha ha

meanwhile , Solved scenario one

In general
