使用UICollectionView實現分屏顯示和ScrollView實現縮放效果；

     小圓點是UIPageControll控制元件， 支援配置選中色和未選中顏色；

   UIScrollView有個zoomScale引數,  通過修改該引數可以縮放ScrollView， 從而實現圖片縮放效果。

        scrollView?.delegate = self
        scrollView?.minimumZoomScale = 1.0    //縮小倍數
        scrollView?.maximumZoomScale = 5.0    //放大倍數
 

        let layout = UICollectionViewFlowLayout()
        layout.minimumLineSpacing = 0
        layout.minimumInteritemSpacing = 0
        layout.itemSize = view.bounds.size    //每條記錄的大小
        layout.scrollDirection = .horizontal
 

collectionView?.isPagingEnabled = true //分屏

 let singleClick = UITapGestureRecognizer(target: self,
                                                 action: #selector(singleClick(_:)))
        singleClick.numberOfTapsRequired = 1   //點選次數
        singleClick.numberOfTouchesRequired = 1  //手指個數
        
        let doubleClick = UITapGestureRecognizer(target: self,
                                                 action: #selector(doubleClick(_:)))
        doubleClick.numberOfTapsRequired = 2
        doubleClick.numberOfTouchesRequired = 1
        
        singleClick.require(toFail: doubleClick)   //雙擊監聽失效時才響應單擊事件
 

    //查詢所在的UIViewController
    func getViewController() -> UIViewController? {
        for view in sequence(first: self.superview, next: {$0?.superview}) {
            if let responder = view?.next{
                if responder.isKind(of: UIViewController.self) {
                    return responder as? UIViewController
                }
            }
        }
        return nil
    }
