ios - 将标签放在 spaceBetweenPoints 中的每个点下

Question

我使用自定义 UIView 来创建此控件，该控件具有 4 个热点，且点之间的间距相同。我正在尝试在这些点的正下方创建标签，似乎第一个标签已正确对齐，但我似乎无法弄清楚为什么所有标签都不正确？

在这里您可以看到每个点之间的空间以及点上的半径。

customSlider?.spaceBetweenPoints = 95
customSlider?.radiusPoint = 5

目前的插图:

    customSlider?.frame = CGRectMake((self.frame.width-335)/2, 20, 335, 34)

    for var i = 0;i<4;i++
    {
        var xPointSpace = 95
        var xPos = xPointSpace * i
        var xSpace = (self.frame.width-335)/2
        var xWidth = Int(xSpace) + xPos
        var xFloat = CGFloat(xWidth)


        var textLabel:UILabel = UILabel(frame: CGRectMake(xFloat, 34, 30, 21))
        textLabel.text = "lol"
        textLabel.backgroundColor = UIColor.redColor()
        textLabel.textAlignment = NSTextAlignment.Center
        textLabel.font = UIFont(name: "HelveticaNeue", size: 12)
        self.addSubview(textLabel)

    }

添加标签:

customSlider?.frame = CGRectMake((self.frame.width-335)/2, 20, 335, 34)

for var i = 0;i<4;i++
{
    var xPointSpace = 95
    var radiusPoint = 5
    var xPos = (xPointSpace + radiusPoint * 2)* i 
    var xSpace = customSlider?.frame.origin.x
    var xWidth = xSpace + xPos
    var xFloat = CGFloat(xWidth)


    var textLabel:UILabel = UILabel(frame: CGRectMake(xFloat, 34, 30, 21))
    textLabel.text = "lol"
    textLabel.backgroundColor = UIColor.redColor()
    textLabel.textAlignment = NSTextAlignment.Center
    textLabel.font = UIFont(name: "HelveticaNeue", size: 12)
    self.addSubview(textLabel)

}
