Specify border radius of UITextField in Swift
提问by Daniel Bramhall
I would like to programmatically specify the border radius of a UITextFieldusing Swift.
我想以编程方式指定UITextField使用 Swift的边界半径。
By default, a UITextFieldhas a slight border radius, however I would like to increase it and, after trawling through Interface Builder, I assume this can be done programmatically?
默认情况下， aUITextField有一个很小的边界半径，但是我想增加它，并且在浏览 Interface Builder 之后，我认为这可以通过编程来完成？

You can use:
您可以使用：
nameOfTextField.layer.cornerRadius = 15.0
nameOfTextField.layer.borderWidth = 2.0
nameOfTextField.layer.borderColor = UIColor.red.cgColor

If you're using Interface Builder, you can use User Defined Runtime Attributes for the controls you want to modify. At runtime, when the view loads, each attribute you pass a key path for will automatically be set to your value. No need to clutter up your code with little display tweaks.
如果您使用的是 Interface Builder，则可以对要修改的控件使用用户定义的运行时属性。在运行时，当视图加载时，您传递关键路径的每个属性都将自动设置为您的值。无需通过很少的显示调整来弄乱您的代码。

As @SnarfSnarf suggests you can programmatically tune the border widht and corner radius of the text field, _and any other view for the matter, by accessing its layerproperties:
正如@SnarfSnarf 建议的那样，您可以通过访问其layer属性，以编程方式调整文本字段的边框宽度和角半径，_和任何其他视图：
nameOfTextField.layer.cornerRadius = 4.0
nameOfTextField.layer.borderWidth = 2.0
On top of that, UITextFieldhas a borderStyleproperty which you might want to play with. It has four possible values: None, Line, Bezel, and RoundedRect.
最重要的是，UITextField有一个borderStyle你可能想玩的属性。它有四个可能的值：None，Line，Bezel，和RoundedRect。
Finally have a read through UITextField's documentation, it's always a good way to find out all the possibility a class provides.
最后通读一下UITextField的文档，它始终是找出类提供的所有可能性的好方法。

Don't forget to add layer.masksToBound - I think the most popular answer missed that. You need the button to have the same form as its' borders. https://developer.apple.com/documentation/quartzcore/calayer/1410896-maskstobounds
不要忘记添加 layer.masksToBound - 我认为最受欢迎的答案忽略了这一点。您需要按钮具有与其边框相同的形式。 https://developer.apple.com/documentation/quartzcore/calayer/1410896-maskstobounds
nameOfTextField.layer.cornerRadius = 15.0
nameOfTextField.layer.borderWidth = 0
nameOfTextField.layer.masksToBounds = true
