如何更改圆形按钮上的边框颜色 (Swift)

Question

我有四个按钮。

并且两个按钮有圆角(1-(top Left, bottom Left),4-(top Right, bottom Right)) 。

如何更改图像上的边框颜色。

// Right Button
let T1 = UIBezierPath(roundedRect:Delete.bounds, byRoundingCorners:[.topRight, .bottomRight], cornerRadii: CGSize(width: 15, height:  15))
    let maskLayer = CAShapeLayer()
    maskLayer.path = T1.cgPath
    Delete.layer.mask = maskLayer
// Left Button
let T2 = UIBezierPath(roundedRect:Copy.bounds, byRoundingCorners:[.topLeft, .bottomLeft], cornerRadii: CGSize(width: 15, height:  15))
    let maskLayer2 = CAShapeLayer()
    maskLayer2.path = T2.cgPath
    Copy.layer.mask = maskLayer2

Answer 1

将您的UIView “containerView”添加为IBOutlet并设置您的containerView.layer.borderWidth = yourDesiredWidth并设置containerView.layer.borderColor = yourNeededColor.cgColor

Answer 2

UIButton.layer.cornerRadius 、 UIButton.layer.borderColor和UIButton.layer.borderWidth 。 layer是UIView一个属性，所以你几乎可以用它自定义任何视图。

Answer 3

button.layer.borderColor = CGColor(srgbRed: 255/255, green: 126/255, blue: 121/255, alpha: 1)
