Question

好吧，我从来没有经历过这个，但不知道如何让它消失：我已经以编程方式创建了几个具有特定背景颜色的UILabel。然而，在某些情况下，在上边框和右边框上，可以看到一条奇怪的深色线条（见第2行标签）：

我不知道造成这种情况的原因。以下是我制作它们的方法：

 for i in 0...featureLabels.count-1
            {
                featureLabels[i] = RSSLinkLabel()
                featureLabels[i]?.frame = CGRect(x: 0, y: 0, width: (overallWidth-(imgSpace))/3, height: ((overallWidth-(imgSpace))/3)/contentRatios[2])
                featureLabels[i]?.text = "Hello label \(i)"
                featureLabels[i]?.backgroundColor = UIColor(hexString: secondColorStr)
                featureLabels[i]?.textAlignment = .left
                featureLabels[i]?.font = iphoneFont

                var pt = CGPoint()
                switch i {
                case 0:
                    pt = CGPoint(x: sideDiff + ((featureLabels[i]?.bounds.width)!/2), y: subContView2.bounds.height - ((featureLabels[i]?.bounds.height)!/2))
                case 1:
                    pt = CGPoint(x: subContView2.bounds.width/2, y: subContView2.bounds.height - ((featureLabels[i]?.bounds.height)!/2))
                case 2:
                    pt = CGPoint(x: sideDiff + (overallWidth - ((featureLabels[i]?.bounds.width)!/2)), y: subContView2.bounds.height - ((featureLabels[i]?.bounds.height)!/2))
                default:
                    break
                }
                featureLabels[i]?.center = pt

                subContView2.addSubview(featureLabels[i]!)
            }

它们是我在此处定义的自定义标签：

import UIKit

class RSSLinkLabel: UILabel {

    var id = String()

    override init (frame : CGRect) {
        super.init(frame : frame)

    }
    func customInit()
    {
        self.text = txtSources[id]
    }

    required public init(coder aDecoder: NSCoder) {
        fatalError("This class does not support NSCoding")
    }

    convenience init () {
        self.init(frame:CGRect.zero)
    }
    override public func layoutSubviews() {
        customInit()
    }

}

我尝试过做featureLabels[i]?.layer.borderColor = UIColor.clear.cgColor但没有任何反应。

如何让这个大纲消失？
