SWIFT:在我的tableViewController中未调用touchesEnded

如何解决SWIFT:在我的tableViewController中未调用touchesEnded

因此,我有一个名为SettingsViewController的tableviewController,它具有以下touchesEnded函数:

override func touchesEnded(_ touches: Set<UITouch>,with event: UIEvent?) {
    if let touch = touches.first {
        print("yoyoyoyoyoyoyoyQVEWEVIWNE")
        let touchLocation = touch.location(in: view)

        // 290 because the width of the view is 414,and the SettingsViewController width gets set to 0.7 * the view width in SlideInTransition.  0.7 * 414 is 289.8
        if touchLocation.x > 200 {
            dismiss(animated: true)
        }
    }
}

我做了打印语句,看它是否被调用,不是。该视图控制器在自定义过渡中带有“菜单式”幻灯片。我怀疑UIView的范围就是问题所在。这是自定义转换代码:

class SlideInTransition: NSObject,UIViewControllerAnimatedTransitioning {

var isPresenting: Bool = false

func transitionDuration(using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval {
    return 0.5
}

func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
    
    // Make sure they exist
    
    // The view controller being transitioned from,using the context (ex: here it's the MapViewController)
    guard let fromViewController = transitionContext.viewController(forKey: .from),// The view controller being transitioned to,using the context (ex: here it's the SettingsTableViewController)
        let toViewController = transitionContext.viewController(forKey: .to) else {return}
    
    let containerView = transitionContext.containerView
    
    // Constants for appearance of SettingsViewController
    
    let vcWidth = toViewController.view.bounds.width * 0.7
    let vcHeight = toViewController.view.bounds.height
    
    if isPresenting {
        // Add SettingsViewController to container
        containerView.addSubview(toViewController.view)
        
        // Initial frame for view controller,off the screen to the left to start,that way it appears to slide in
        toViewController.view.frame = CGRect(x: -vcWidth,y: 0,width: vcWidth,height: vcHeight)
    }
    
    // Animate view controller onto the screen,sliding in from left
    let transform = {
        toViewController.view.transform = CGAffineTransform(translationX: vcWidth,y: 0)
        }
    
    // Animate back off screen
    let identity = {
        // .identity returns the vc to the initial frame,as created above in the isPresenting if statement
        fromViewController.view.transform = .identity
    }
    
    // Animation of the transition
    let duration = transitionDuration(using: transitionContext)
    let isCancelled = transitionContext.transitionWasCancelled
    UIView.animate(withDuration: duration,animations: {
        // If presenting,transform SettingsViewController (to) onto screen,otherwise set it back off the screen.
        self.isPresenting ? transform() : identity()
    }) { (Bool) in
        transitionContext.completeTransition(!isCancelled)
    }
    
}

}

我编写了touchesEnded代码,以便当用户在viewController外部触摸时,它会退出(视图控制器仅是屏幕宽度的70%),但是无论我在屏幕上的什么位置,它都不会被调用点击。知道为什么吗?谢谢。

解决方法

«如果您在不调用super的情况下重写此方法(一种常用模式),则即使您的实现不执行任何操作,也必须重写其他方法来处理触摸事件。»

这将是一个开始。
