Swift 如何在macOS上使用AppKit使鼠标滚轮水平滚动

我的应用程序只有一行的NSCollectionView。我想用鼠标滚轮使其水平滚动，但不想同时按下shift键

因此，如何使用macOS上的AppKit转换滚动方向？您可以将NSCollectionView子类化并覆盖scrollWheel

import Cocoa

class YourCollectionView: NSCollectionView {

    override func scrollWheel(with event: NSEvent) {
        // get mouse wheel scroll offset
        let scrollOffset = event.scrollingDeltaY

        // scroll collectionView your self, maybe like this
        if let clipView = self.enclosingScrollView?.contentView as? NSClipView {
            let currentPoint = self.visibleRect.origin
            let newPoint = CGPoint(x: currentPoint.x + scrollOffset ,y: currentPoint.y)
            clipView.scroll(to: newPoint)
        }
    }
}

你可以试一试，希望这能对你有所帮助
