情况1-自定义segmentedControl中每个元素的borderColor

码

extension UIView {
    ///Add border color with corners
    func addBorderWithColor(color: UIColor, roundingCorners: UIRectCorner) {
        self.layer.borderWidth = 1
        self.layer.borderColor = color.CGColor
        self.addRoundingCorners(roundingCorners)
    }

    ///Use corner radius depending on UIRectCorner
    private func addRoundingCorners(roundingCorners: UIRectCorner) {
        let path = UIBezierPath(roundedRect:self.bounds, byRoundingCorners:roundingCorners, cornerRadii: CGSizeMake(4, 4))

        let maskLayer = CAShapeLayer()
        maskLayer.path = path.CGPath
        self.layer.mask = maskLayer
    }
}

let segmentedControl = UISegmentedControl(items: ["Red", "Green", "Blue"])

segmentedControl.subviews[0].addBorderWithColor(UIColor.blueColor(), roundingCorners: [.TopRight, .BottomRight])
segmentedControl.subviews[1].addBorderWithColor(UIColor.greenColor(), roundingCorners: [])
segmentedControl.subviews[2].addBorderWithColor(UIColor.redColor(), roundingCorners: [.TopLeft, .BottomLeft])

segmentedControl.setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.blackColor()], forState: UIControlState.Normal)

案例2-摆脱国界

码

let segmentedControl = UISegmentedControl(items: ["Red", "Green", "Blue"])

//Change Text Attributes (Changing textColor to black)
//**Be sure to manage all the UIControlState for these attributes if you need to customize this for other states
segmentedControl.setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.blackColor()], forState: UIControlState.Normal)

//Change tintColor to clear, in order to set border invisible
segmentedControl.tintColor = UIColor.clearColor()
