我正在设置一个简单的tvOS应用程序,底部有一个菜单坞(包含按钮的堆栈视图)。在5秒不活动后,我希望停靠隐藏(向下移动,移出视图)并从当前聚焦按钮中移除焦点。码头应重新出现,并重新集中于遥控活动。使用以下代码,dock将隐藏,但仅在应用程序启动后隐藏一次。任何帮助都将不胜感激!
@IBOutlet weak var menuDock: UIStackView!
var timer = Timer()
func resetTimer() {
timer = Timer.scheduledTimer(timeInterval: 5.0, target: self, selector: #selector(ViewController.hideDock), userInfo: nil, repeats: true)
let tapRecognizer = UITapGestureRecognizer(target: self, action: #selector(ViewController.showDock))
self.view.addGestureRecognizer(tapRecognizer)
}
@objc func hideDock() {
UIView.animate(withDuration: 0.5, animations: {
self.menuDock.frame.origin.y += 240
}, completion: nil)
timer.invalidate()
}
@objc func showDock() {
UIView.animate(withDuration: 0.5, animations: {
self.menuDock.frame.origin.y -= 240
}, completion: nil)
timer = Timer.scheduledTimer(timeInterval: 5, target: self, selector: #selector(ViewController.hideDock), userInfo: nil, repeats: true)
timer.invalidate()
}
