为用户禁用可视编辑器后，我仍然不能只输入html代码。我在那里找到了extension UIView {
func addDashedBorder(_ color: UIColor = UIColor.black, withWidth width: CGFloat = 2, cornerRadius: CGFloat = 5, dashPattern: [NSNumber] = [3,6]) {
let shapeLayer = CAShapeLayer()
shapeLayer.bounds = bounds
shapeLayer.position = CGPoint(x: bounds.width/2, y: bounds.height/2)
shapeLayer.fillColor = nil
shapeLayer.strokeColor = color.cgColor
shapeLayer.lineWidth = width
shapeLayer.lineJoin = CAShapeLayerLineJoin.round // Updated in swift 4.2
shapeLayer.lineDashPattern = dashPattern
shapeLayer.path = UIBezierPath(roundedRect: bounds, cornerRadius: cornerRadius).cgPath
self.layer.addSublayer(shapeLayer)
}
}
视觉编辑器。
