Swift Radio按钮不可点击

Question

我通过DLRadioButton找到了Cocoa Pods

来使用Int库

下面是我的代码，基本上是单选按钮出现但是我只能在组中单击其中一个，我不确定为什么。请注意，我根据Firebase中的` override func viewDidLoad() { super.viewDidLoad() ref = FIRDatabase.database().reference() pollRef = ref.child("Polls").child(pass) passLabel.text = pass pollImage.sd_setImage(with: URL(string: passedImageURL), placeholderImage: UIImage(named: "test")) pollRef.observe(FIRDataEventType.value, with: {(snapshot) in self.numberOfChildren = Int(snapshot.childSnapshot(forPath: "answers").childrenCount) self.passLabel.text = String(self.numberOfChildren) print(self.numberOfChildren) var buttons = [DLRadioButton]() for x in 0..<self.numberOfChildren { let answerLabel = snapshot.childSnapshot(forPath: "answers").childSnapshot(forPath: String(x+1)).childSnapshot(forPath: "answer").value let firstRadioButton = self.createRadioButton(frame: CGRect(x: CGFloat(x)*32, y:self.view.center.y , width: 40.0, height: 20.0), title: answerLabel as! String, color: UIColor.black) // firstRadioButton.translatesAutore sizingMaskIntoConstraints = false let screenSize: CGRect = UIScreen.main.bounds firstRadioButton.frame = CGRect(x: 0, y: 0, width: 50, height: screenSize.height * 0.2) firstRadioButton.tag = x buttons.append(firstRadioButton) self.view.addSubview(firstRadioButton); } let groupButtons = DLRadioButton() groupButtons.translatesAutoresizingMaskIntoConstraints = false self.view.addSubview(groupButtons) let margins = self.view.layoutMarginsGuide groupButtons.bottomAnchor.constraint(equalTo: margins.bottomAnchor, constant: 0).isActive = true groupButtons.otherButtons = buttons }) } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } private func createRadioButton(frame : CGRect, title : String, color : UIColor) -> DLRadioButton { let radioButton = DLRadioButton(frame: frame); radioButton.titleLabel!.font = UIFont.systemFont(ofSize: 14); radioButton.setTitle(title, for: UIControlState.normal); radioButton.setTitleColor(color, for: UIControlState.normal); radioButton.iconColor = color; radioButton.indicatorColor = color; radioButton.contentHorizontalAlignment = UIControlContentHorizontalAlignment.left; radioButton.addTarget(self, action: #selector(self.logSelectedButton(_:)), for: UIControlEvents.touchUpInside); return radioButton; } @IBAction func logSelectedButton(_ radioButton: DLRadioButton) { if radioButton.isMultipleSelectionEnabled { for button: DLRadioButton in radioButton.selected() { print("\(button.titleLabel?.text) is selected.\n") } } else { print("\(radioButton.selected()?.titleLabel?.text) is selected.\n") } } 填充了单选按钮，表示要填充的数量：

你需要选择按钮的方法

let firstRadioButton = self.createRadioButton(frame: CGRect(x: self.view.center.x, y: CGFloat(x)*32, width: 100.0, height: 120.0), title: answerLabel as! String, color: UIColor.green)
firstRadioButton.tag = x
firstRadioButton.addTarget(self, action: #selector(self.logSelectedButton), for: .touchUpInside)
buttons.append(firstRadioButton)

选择器方法：您可以根据需要进行更改

@IBAction func logSelectedButton(_ radioButton: DLRadioButton) {
        if radioButton.isMultipleSelectionEnabled {
            for button: DLRadioButton in radioButton.selectedButtons {
                print("\(button.titleLabel?.text) is selected.\n")
            }
        }
        else {
            print("\(radioButton.selectedButton.titleLabel?.text) is selected.\n")
        }
    }
