UIlabel layer.cornerRadius not working in iOS 7.1
提问by Mike V
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.
我目前正在查看一个带有属性的 UILabeladdMessageLabel.layer.cornerRadius = 5.0f;在安装了 iOS 7.0 的设备上，它有圆角。在安装了 iOS 7.1 的设备上，它没有圆角。
Is this just a bug with iOS 7.1?
这只是 iOS 7.1 的一个错误吗？

Set the property clipsToBoundsto true
将属性设置clipsToBounds为 true
addMessageLabel.clipsToBounds = true

I think the best way to set corner radius is:
我认为设置拐角半径的最佳方法是：
and be sure the "Clip Subviews" is checked:
并确保选中“剪辑子视图”：
Checking "Clip Subviews" is equal to the code addMessageLabel.clipsToBounds = YES;.
检查“剪辑子视图”等于代码addMessageLabel.clipsToBounds = YES;。

Try the followings,
尝试以下方法，
[[addMessageLabel layer] setCornerRadius:5.0f];
[[addMessageLabel layer] setMasksToBounds:YES];
//or
[addMessageLabel setClipsToBounds:YES];
Swift
迅速
addMessageLable.layer.cornerRadius = 5.0
addMessageLable.layer.masksToBounds = true
//or
addMessageLable.layer.clipsToBounds = true

My issue was a bit different.
我的问题有点不同。
While I diddo btn.clipsToBounds = true
虽然我没做 btn.clipsToBounds = true
I wasn't setting doing:
我没有设置做：
btn.layer.cornerRadius = 20
Because I had different screen sizes. Instead I followed thisanswer and did:
因为我有不同的屏幕尺寸。相反，我遵循了这个答案并做了：
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:
它不起作用，因为我忘记添加super.layoutSubviews(). 正确的代码是：
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.
我已经尝试了下面的一个，我得到了一个成功的输出。
yourlabelname.layer.cornerRadius = 10.0f;
[yourlabelname setClipsToBounds:YES];
Is there something else which is stopping you?
还有什么阻止你的吗？

//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by iAmita Singh
yourlabelname.layer.cornerRadius = yourlabelname.frame.size.width/2;
[yourlabelname setClipsToBounds:YES];
Make sure you are checking with appropriate Deployment target.
确保您正在检查适当的部署目标。

Add the Following Code as extension for UIView
添加以下代码作为 UIView 的扩展
//// 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.!
之后，您将在界面构建器本身中获得以下属性。！
