我有一个名为的按钮,我给了它一个UIGestureRecognizer,这样一个IBAction只在按钮被长按时运行。您可以通过向按钮本身添加UILongPressGestureRecognizer来实现。然后你控制拖动那个手势识别器到一个像这样的函数:@IBActionfunchandleGesture(sender:UIGestureRecognizer){ifsender.state==UIGestureRecognizerState.Began{letlabelTap1=UITapGestureRecognizer(target:self,action:"labelTapped

我目前在ViewDidLoad()中创建并添加到UIView的subview。我正在尝试使用UIGestureRecognizers来检测点击并取消隐藏特定按钮。我当前的代码:overridefuncviewDidLoad(){super.viewDidLoad()architectView=CustomClass(frame:self.view.bounds)self.view.addSubview(architectView)letgestureRecognizer=UITapGestureRecognizer(target:self,action:"handleTap:")ges

在我的UINavigationController中,我添加了自定义后退按钮,其副作用是无法再从左向右滑动以弹出ViewController并向后导航。所以我在自定义UINavigationController类中实现了interactivePopGestureRecognizer:classUINavigationControllerExtended:UINavigationController,UIGestureRecognizerDelegate{overridefuncviewDidLoad(){super.viewDidLoad()ifself.respondsToSelec

我已经完成了单击识别器,但无法弄清楚如何将单击识别器变成双击识别器。我需要一些指导。代码:importFoundationimportUIKitclassMainBoardController:UIViewController{lettap=UITapGestureRecognizer()overridefuncviewDidLoad(){super.viewDidLoad()//Doanyadditionalsetupafterloadingtheview,typicallyfromanib.varswipe:UISwipeGestureRecognizer=UISwipeGestu
