我通过DLRadioButton
找到了Cocoa Pods
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:
index

答案 0 :(得分:1)
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")
}
}
