UIlabel layer.cornerRadius not working in iOS 7.1

问题

I'm currently looking at a UILabel with the property addMessageLabel.layer.cornerRadius = 5.0f; On a device with iOS 7.0 installed, it has rounded corners. On a device with iOS 7.1 installed, it does not have rounded corners.

Is this just a bug with iOS 7.1?

回答1:

Set the property clipsToBounds to true

addMessageLabel.clipsToBounds = true

回答2:

I think the best way to set corner radius is:

and be sure the "Clip Subviews" is checked:

Checking "Clip Subviews" is equal to the code addMessageLabel.clipsToBounds = YES;.

回答3:

Add the below two line and check it.

[[addMessageLabel layer] setCornerRadius:5.0f];
[[addMessageLabel layer] setMasksToBounds:YES];

[addMessageLabel setClipsToBounds:YES];

My issue was a bit different.

While I did do btn.clipsToBounds = true

I wasn't setting doing:

btn.layer.cornerRadius = 20

Because I had different screen sizes. Instead I followed this answer and did:

override func layoutSubviews() {
    seeMoreButton.layer.cornerRadius = seeMoreButton.bounds.size.height / 2
}

It wasn't working because I forgot to add super.layoutSubviews(). The correct code is:

override func layoutSubviews() {
    super.layoutSubviews()
    seeMoreButton.layer.cornerRadius = seeMoreButton.bounds.size.height / 2
}

I have tried the below one and i got an successful output.

yourlabelname.layer.cornerRadius = 10.0f;
[yourlabelname setClipsToBounds:YES];

Is there something else which is stopping you?

 //works perfect in Swift 2.0 for a circular or round image          


@IBOutlet var theImage: UIImageView!
        override func viewDidLoad() {
            super.viewDidLoad()
    //Make sure the width and height are same
            self.theImage.layer.cornerRadius = self.theImage.frame.size.width / 2
            self.theImage.layer.borderWidth = 2.0
            self.theImage.layer.borderColor = UIColor.whiteColor().CGColor
            self.theImage.clipsToBounds = true

        }

回答7:

yourlabelname.layer.cornerRadius = yourlabelname.frame.size.width/2;
[yourlabelname setClipsToBounds:YES];

Make sure you are checking with appropriate Deployment target.

Add the Following Code as extension for UIView

//// Story board Extra Feature for create border radius, border width and border Color
extension UIView {
    /// corner radius
    @IBInspectable var borderColor: UIColor? {
        set {
            layer.borderColor = newValue!.cgColor
        }
        get {
            if let color = layer.borderColor {
                return UIColor(cgColor: color)
            } else {
                return nil
            }
        }
    }
    @IBInspectable var borderWidth: CGFloat {
        set {
            layer.borderWidth = newValue
        }
        get {
            return layer.borderWidth
        }
    }
    @IBInspectable var cornerRadius: CGFloat {
        set {
            layer.cornerRadius = newValue
            clipsToBounds = newValue > 0
        }
        get {
            return layer.cornerRadius
        }
    }
}

After that you will get the following attributes in interface builder itself.!
