我正在尝试在rotate:中实现smartMagnify:，但它永远不会被调用。我有magnify:，class FigOSXLayerView: FigOSXLayerViewBase /* NSView subclass */ {
var layerViewController: FigOSXLayerVC?
private var _scale: CGFloat = 1.0
override func draw(_ dirtyRect: NSRect) {
self.properties.showSelectionHighlight = true
self.properties.showAnnotation = true
self.properties.showPoints = true
super.draw(dirtyRect)
}
// ************************
// MARK: Zoom, pan, rotate
// ************************
override func magnify(with event: NSEvent) {
self._scale = 1 + event.magnification
self.layerViewController?.scale(self._scale)
}
override func rotate(with event: NSEvent) {
self.layerViewController?.rotate(CGFloat(event.rotation.toRadians))
}
override func scrollWheel(with event: NSEvent) {
self.layerViewController?.translate(dx: event.deltaX, dy: -event.deltaY)
}
override func smartMagnify(with event: NSEvent) {
Swift.print("Smart magnify") // Not called
}
// ...
}
等等，并且它们都被成功调用 - 我需要做什么才能收到此消息？我搜索过的文档非常稀疏，没有理由不调用它。
我认为这与我的代码相关......

只是通过迷信，我已经尝试将自己设置为第一响应者，以防它与此有关，但这没有任何区别。
