PopUpDialog cocoapod自定义按钮不起作用

编程问答 2022-06-09

问题描述

我在我的应用程序https://cocoapods.org/pods/PopupDialog中使用了这个PopUpDialog cocoapod

我已经制作了一个自定义VC，并且希望我的两个按钮在单击时增加/减少FurnitureLabel上显示的数字（标签在按钮上方的弹出对话框中）。 这是我的弹出窗口的样子：

PopUp dialogbox

我不知道我缺少什么，但是当我创建两个按钮时，我都收到了这个错误消息：表达类型不明确，没有更多上下文。

它显示在该行的旁边：

furnitureVC.furnitureLabel.text = String(Int(furnitureVC.furnitureLabel.text) - 1)

您能否更正我的代码才能正常工作？

func handleForward(animated: Bool = true) {

     //Create a custom view controller
    let furnitureVC = FurniturePopUp(nibName: "FurniturePopUp",bundle: nil)


     //Create the dialog
    var popup = PopupDialog(viewController: furnitureVC,buttonAlignment: .horizontal,transitionStyle: .bounceDown,tapGesturedismissal: true,panGesturedismissal: false)
    
    
    let vc = popup.viewController as! PopupDialogdefaultviewController

    // Set dialog properties
    
    vc.titleText = "..."
    vc.messageText = "0"
    
    
    
    // Create first button
    let buttonOne = DefaultButton(title: "Decrease",height: 60,dismissOnTap: false) {
        furnitureVC.furnitureLabel.text = String(Int(furnitureVC.furnitureLabel.text) - 1)
        vc.messageText = furnitureVC.furnitureLabel.text
    }

    // Create second button
    let buttonTwo = DefaultButton(title: "Increase",dismissOnTap: false) {
        furnitureVC.furnitureLabel.text = String(Int(furnitureVC.furnitureLabel.text) + 1)
        
            
    }
    buttonOne.setimage(#imageLiteral(resourceName: "minus").withRenderingMode(.alwaysOriginal),for: .normal)
    buttonTwo.setimage(#imageLiteral(resourceName: "plus").withRenderingMode(.alwaysOriginal),for: .normal)

    // Add buttons to dialog
    popup.addButtons([buttonOne,buttonTwo])

    // Present dialog
    present(popup,animated: animated,completion: nil)
}

FurniturePopUp：

    class FurniturePopUp: UIViewController {
    @IBOutlet weak var decreaseButton: UIButton!
    @IBOutlet weak var increaseButton: UIButton!
    @IBOutlet weak var furnitureLabel: UILabel!
    
}
