我正在嘗試通過故事板創建的UIStackView中的單選按鈕。但是,基於Firebase中的數據以編程方式在UIStackView中創建單選按鈕。無法在UIStackView中設置編程佈局約束條件
我使用DLRadioButtons提供的庫。
UIStackView以下標籤,命名radioStackView:其中單選按鈕基於火力地堡數據相加
代碼:
`
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: 1, y:1 , width: 80.0, height: 1.0), title: answerLabel as! String, color: UIColor.black)
firstRadioButton.tag = x
firstRadioButton.translatesAutoresizingMaskIntoConstraints = false
buttons.append(firstRadioButton)
let margins = self.radioStackView.layoutMarginsGuide
firstRadioButton.topAnchor.constraint(equalTo: margins.topAnchor, constant: 5).isActive = true
self.radioStackView.addArrangedSubview(firstRadioButton)
}
let groupButtons = DLRadioButton()
groupButtons.otherButtons = buttons
})
}

` 輸出:按鈕不是直接在彼此的頂部上堆疊;試着玩界面生成器,但仍然無法刪除間距
感謝您的幫助,我已經更新了代碼。我不能讓按鈕直接堆疊在一起。有什麼想法嗎? – tccpg288

我使用界面生成器,我正在使用這些設置並且間距沒有改變。 – tccpg288
