UITextField Only Top And Bottom Border

One approach I have found works good is using layers. Here's a snippet:

CALayer *bottomBorder = [CALayer layer];bottomBorder.frame = CGRectMake(0.0f, self.frame.size.height - 1, self.frame.size.width, 1.0f);bottomBorder.backgroundColor = [UIColor blackColor].CGColor;[myTextField.layer addSublayer:bottomBorder];

Hope this helps someone.

@user3075378's great & simple example in Swift

var bottomBorder = CALayer()bottomBorder.frame = CGRectMake(0.0, textField.frame.size.height - 1, textField.frame.size.width, 1.0);bottomBorder.backgroundColor = UIColor.blackColor().CGColortextField.layer.addSublayer(bottomBorder)

@Sebyddd why stop there? (;

EDIT: There is an issue with lines being drawn before auto layout sets the right frame for the view, I edited my answer with a fix: it basically involves calling drawLines() in layoutSubviews():

class FramedTextField: UITextField {    @IBInspectable var linesWidth: CGFloat = 1.0 { didSet{ drawLines() } }    @IBInspectable var linesColor: UIColor = UIColor.blackColor() { didSet{ drawLines() } }    @IBInspectable var leftLine: Bool = false { didSet{ drawLines() } }    @IBInspectable var rightLine: Bool = false { didSet{ drawLines() } }    @IBInspectable var bottomLine: Bool = false { didSet{ drawLines() } }    @IBInspectable var topLine: Bool = false { didSet{ drawLines() } }    func drawLines() {        if bottomLine {            add(CGRectMake(0.0, frame.size.height - linesWidth, frame.size.width, linesWidth))        }        if topLine {            add(CGRectMake(0.0, 0.0, frame.size.width, linesWidth))        }        if rightLine {            add(CGRectMake(frame.size.width - linesWidth, 0.0, linesWidth, frame.size.height))        }        if leftLine {            add(CGRectMake(0.0, 0.0, linesWidth, frame.size.height))        }    }    typealias Line = CGRect    private func add(line: Line) {        let border = CALayer()        border.frame = line        border.backgroundColor = linesColor.CGColor        layer.addSublayer(border)    }    override func layoutSubviews() {        super.layoutSubviews()        drawLines()    }}
