NSPageController，如果在 animator() 中使用了 selectedIndex，则 autoresizingMask 无效

Question

如果在 animator() 中使用了 selectedIndex，则 autoresizingMask 无效。
如果你不使用 animator()，你很好。
无法使用 animator() 手动执行 selectedIndex。

知道的请告诉我

self.animator().selectedIndex = 2

self.selectedIndex = 2

let array = ["page 1", "page 2", "page 3", "page 4", "page 5", "page 6"]

class PageController: NSPageController, NSPageControllerDelegate {

    @IBAction func moveThreePage(_ sender: Any) {
        // NG
        self.animator().selectedIndex = 2

        // OK
        //self.selectedIndex = 2
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        self.delegate = self
        self.arrangedObjects = array
    }

    func pageController(_ pageController: NSPageController, viewControllerForIdentifier identifier: String) -> NSViewController {
        let vc = self.storyboard!.instantiateController(withIdentifier: "ViewController") as! ViewController
        vc.view.autoresizingMask = [.height, .width]
        return vc
    }

    func pageController(_ pageController: NSPageController, identifierFor object: Any) -> String {
        return "ViewController"
    }

    func pageController(_ pageController: NSPageController, prepare viewController: NSViewController, with object: Any?) {
        guard let item = object as? String,
              let itemVC = viewController as? ViewController else {
            return
        }

        itemVC.item = item
    }

    func pageControllerDidEndLiveTransition(_ pageController: NSPageController) {
        self.completeTransition()
    }
}

谢谢。完成了。

@IBAction func moveThreePage(_ sender: Any) {
    //To animate a selectedIndex change:
    NSAnimationContext.runAnimationGroup({ context in
        self.animator().selectedIndex = 2
    }, completionHandler: {
        self.completeTransition()
    })
}

NSPageController，如果在 animator() 中使用了 selectedIndex，则 autoresizingMask 无效

NSPageController, If selectedIndex is used at animator(), autoresizingMask has no effect
