UITextField Only Top And Bottom Border

Question

I currently have a regular border. I would like to only have a top and bottom border.

How do I accomplish this?

Using the UITextField<

Answer 1

@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().CGColor
textField.layer.addSublayer(bottomBorder)

You can also add views to the top and bottom to use as borders.

// Top border
UIView *topBorder = [[UIView alloc]
    initWithFrame:CGRectMake(0,
                             0,
                             textfield.frame.size.width,
                             4.0f)];
topBorder.backgroundColor = [UIColor colorWithRed:160/255.0f
                                            green:160/255.0f
                                             blue:160/255.0f
                                            alpha:1.0f];
[textfield addSubview:topBorder];

// Bottom border
UIView *bottomBorder = [[UIView alloc]
    initWithFrame:CGRectMake(0,
                             textfield.frame.origin.y +
                                 textfield.frame.size.height - 4.0f,
                             textfield.frame.size.width,
                             4.0f)];
bottomBorder.backgroundColor = [UIColor colorWithRed:160/255.0f
                                               green:160/255.0f
                                                blue:160/255.0f
                                               alpha:1.0f];
[textfield addSubview:bottomBorder];

Answer 3

you can create one image that with top and bottom border and set it to the background of your UITextField :

yourTextField.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"yourBorderedImageName"]];

Answer 4

Thanks to user3075378. my answer is based on his. adding right and left small lines.

- (void)styleSearchTextField {
    CALayer *bottomBorder = [CALayer layer], *leftBorder = [CALayer layer], *rightBorder = [CALayer layer];

    CGFloat thickness = 1.0f;
    CGFloat side_height = 6.0f;

    bottomBorder.frame = CGRectMake(0.0f, searchTextField.frame.size.height - 1, searchTextField.frame.size.width, thickness);

    leftBorder.frame = CGRectMake(0.0f, searchTextField.frame.size.height - side_height, thickness, searchTextField.frame.size.height - 1);

    rightBorder.frame = CGRectMake(searchTextField.frame.size.width - 1, searchTextField.frame.size.height - side_height, thickness, searchTextField.frame.size.height - 1);

    bottomBorder.backgroundColor = [self.stylingDetails themeGrayColor].CGColor;
    leftBorder.backgroundColor = [self.stylingDetails themeGrayColor].CGColor;
    rightBorder.backgroundColor = [self.stylingDetails themeGrayColor].CGColor;

    [searchTextField.layer addSublayer:bottomBorder];
    [searchTextField.layer addSublayer:leftBorder];
    [searchTextField.layer addSublayer:rightBorder];
}

Swift 3: Clean with AutoLayout (I'm using here PureLayout but you can also do it with common NSLayoutConstraint:

func makeUnderline(for textField: UITextField) {
    let borderLine = UIView()
    borderLine.backgroundColor = UIColor.black
    borderLine.autoSetDimension(.height, toSize: 1)
    textField.addSubview(borderLine)
    borderLine.autoPinEdgesToSuperviewEdges(with: UIEdgeInsets.zero, excludingEdge: .top)
}

Answer 6

I will suggest you put one view on the left side of the textfield and one view on the right side of the textfield to cover the left/right border.

UIView *v1 = [[UIView all] initWithFrame:CGRectMake(textfield.frame.origin.x - 5, textfield.frame.origin.y, 10, textifield.frame.size.height)];
UIView *v2 = [[UIView all] initWithFrame:CGRectMake(textfield.frame.origin.x + textfield.frame.size.with - 5, textfield.frame.origin.y, 10, textifield.frame.size.height)];
