如何自定义UITableview右边,上边和下边框？

Question

如何在UITableview中快速设置右边,左边,上边和下边框的颜色？

谢谢,

Answer 1

试试这个全边框:

yourtable.layer.masksToBounds = true
yourtable.layer.borderColor = UIColor( red: 153/255, green: 153/255, blue:0/255, alpha: 1.0 ).CGColor
yourtable.layer.borderWidth = 2.0

这是针对底部边框:

let border = CALayer()
let width = CGFloat(2.0)
border.borderColor = UIColor.darkGrayColor().CGColor
border.frame = CGRect(x: 0, y: yourtable.frame.size.height - width, width:  yourtable.frame.size.width, height: yourtable.frame.size.height)

border.borderWidth = width
yourtable.layer.addSublayer(border)
yourtable.layer.masksToBounds = true

Answer 2

extension UIView {
    func addBorderTop(size size: CGFloat, color: UIColor) {
        addBorderUtility(x: 0, y: 0, width: frame.width, height: size, color: color)
    }
    func addBorderBottom(size size: CGFloat, color: UIColor) {
        addBorderUtility(x: 0, y: frame.height - size, width: frame.width, height: size, color: color)
    }
    func addBorderLeft(size size: CGFloat, color: UIColor) {
        addBorderUtility(x: 0, y: 0, width: size, height: frame.height, color: color)
    }
    func addBorderRight(size size: CGFloat, color: UIColor) {
        addBorderUtility(x: frame.width - size, y: 0, width: size, height: frame.height, color: color)
    }
    private func addBorderUtility(x x: CGFloat, y: CGFloat, width: CGFloat, height: CGFloat, color: UIColor) {
        let border = CALayer()
        border.backgroundColor = color.CGColor
        border.frame = CGRect(x: x, y: y, width: width, height: height)
        layer.addSublayer(border)
    }
}

我将在某些时候开源我的扩展类.
