圆角到UITextField Xcode

Question

I have two textfield (username & password) and want to make top rounded corner for username and bottom rounded corner for password as per attachment.

Answer 1

Just create a UIView .

Put your two text fields in the UIView . Remove the border style of UITextField .

yourView.layer.cornerRadius = 10.0
yourView.clipsToBounds = true

Answer 2

Just follow the below steps

STEP 1:Import QuartzCore framework in you class:

      #import <QuartzCore/QuartzCore.h>

STEP 2:Apply the coding

      textField.layer.cornerRadius=6.0f;
      textField.layer.masksToBounds=YES;
      textField.layer.borderColor=[[UIColor blueColor]CGColor];
      textField.layer.borderWidth= 1.0f; 

         or

      [textField.layer setBorderColor:[[UIColor blueColor] CGColor]];
      [textField.layer setBorderWidth:2.o];
      [textField.layer setCornerRadius:5.0]; 

Answer 3

You can use:

(UIBezierPath *)bezierPathWithRoundedRect:(CGRect)rect byRoundingCorners:(UIRectCorner)corners cornerRadii:(CGSize)cornerRadii

Example:

UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:textField.bounds byRoundingCorners:(UIRectCornerBottomLeft | UIRectCornerBottomRight) cornerRadii:CGSizeMake(10.0, 10.0)];

CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];
maskLayer.frame = self.view.bounds;
maskLayer.path  = maskPath.CGPath;
textField.layer.mask = maskLayer;

Answer 4

I think you should be write CALayer extension. Swift 3.x - 4.x

extension CALayer {

    func addRadius(_ corners: UIRectCorner, radius: CGFloat, view: UIView) {
        let mask = CAShapeLayer()
        mask.bounds = view.frame
        mask.position = view.center
        mask.path = UIBezierPath(roundedRect: view.bounds, byRoundingCorners: corners, cornerRadii: CGSize(width: radius, height: radius)).cgPath
        view.layer.mask = mask
    }

    func addRadius(radius: CGFloat) {
        self.cornerRadius = radius
    }  
}

Use of

    class ViewController: UIViewController {

        @IBOutlet var messageTextField: UITextField!

        override func viewDidLoad() {
            super.viewDidLoad()
            messageTextField.layer.addRadius(radius: 8.0)
        }
    }

Hope your help :)

Here is a full code sample:

import UIKit

class RoundedTextField: UITextField {

    override func awakeFromNib() {
        self.layer.cornerRadius = 10.0 //self.frame.size.height/2
        self.clipsToBounds = false

        super.awakeFromNib()
    }
}
