iOS多Window手势处理(Window手势传递)

先上代码,这也是我的处理方法(有不对地方请指教)

//CallWindow当前悬浮窗window，此window是全屏的，只有上面的view才是缩小(悬浮)的。
override public func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {
  //判断手势是否点悬浮view上(我的是电话view)
  if isTouchCallView(point: point) {
        //当前window响应
        return super.hitTest(point, with: event)
  }
  for keyWindow in UIApplication.shared.windows.reversed() {
        if (keyWindow is CallWindow) == false {
             //倒序遍历取到上一个window响应
             return keyWindow.hitTest(point, with: event)
        }
  }
  return super.hitTest(point, with: event)
}

当然其他的配套需要准备齐全：这些都是依葫芦画瓢
public override func convert(_ point: CGPoint, to window: UIWindow?) -> CGPoint
public override func convert(_ point: CGPoint, from window: UIWindow?) -> CGPoint
public override func convert(_ rect: CGRect, to window: UIWindow?) -> CGRect
public override func convert(_ rect: CGRect, from window: UIWindow?) -> CGRect

判断点击：

 func isTouchCallView(point:CGPoint? = nil,rect:CGRect? = nil) ->(Bool) {
        
        //这儿写得就很low了，直接把悬浮view的frame存起来
        if let point = point,let array:[CGFloat] = (UserDefaults.standard.object(forKey: "CacheWithSuspensionViewFrame") as? [CGFloat]),array.count > 0 {
            let callRect = CGRect.init(x: array[0], y: array[1], width: array[2], height: array[3])
            if callRect.size.width == UIScreen.main.bounds.size.width {
                return true
            }
            return callRect.contains(point)
        }
        
        if let rect = rect,let array:[CGFloat] = (UserDefaults.standard.object(forKey: "CacheWithSuspensionViewFrame") as? [CGFloat]),array.count > 0 {
            let callRect = CGRect.init(x: array[0], y: array[1], width: array[2], height: array[3])
            if callRect.size.width == UIScreen.main.bounds.size.width {
                return true
            }
            return callRect.contains(rect)
        }
        return true
    }

添加悬浮window：

let window:CallWindow = CallWindow.init(frame: MainFrame)
window.windowLevel = .alert + 1
let controller = CallViewController.init()
window.rootViewController = controller
//window需要被持有，否则只会闪显(显示1秒后就消失),我这儿是被单例持有。
self.callWindow = window
self.callWindow?.makeKeyAndVisible()

删除悬浮window：

for window in UIApplication.shared.windows.reversed() {
    if (window is CallWindow) == false {
        window.makeKeyAndVisible()
         break
    }
}
self.callWindow?.isHidden = true
self.callWindow = nil

为何今天想写着这个，也是有感而发！
最近项目上需要做语音视频悬浮框，有两种实现方法：
1、view加到kyewindow上
2、另外添加一个window，设置makeKeyAndVisible()
哎，说多了！一开始我是选择第一种，后面因为与其他功能冲突改为第二种。
