Swift 倾斜矩形的一条边
我正试图在斯威夫特中倾斜一条尤比齐尔路径的边缘。我相信您可以通过在其中一条边上使用“移动”来实现这一点。与下文类似—Swift 倾斜矩形的一条边,swift,uibezierpath,Swift,Uibezierpath,我正试图在斯威夫特中倾斜一条尤比齐尔路径的边缘。我相信您可以通过在其中一条边上使用“移动”来实现这一点。与下文类似— let offset: CGFloat = 60.0; let path = UIBezierPath() let width = self.bounds.width - offset let upperLeftPoint = CGPoint(x: self.bounds.origin.x + width + offset, y: self.bounds.origin.y)
let offset: CGFloat = 60.0;
let path = UIBezierPath()
let width = self.bounds.width - offset
let upperLeftPoint = CGPoint(x: self.bounds.origin.x + width + offset, y: self.bounds.origin.y)
let upperRightPoint = CGPoint(x: self.bounds.origin.x, y: self.bounds.origin.y)
let lowerRightPoint = CGPoint(x: self.bounds.origin.x, y: self.bounds.size.height)
let lowerLeftPoint = CGPoint(x: width - offset, y: self.bounds.size.height)
path.move(to: upperLeftPoint)
path.addLine(to: upperRightPoint)
path.addLine(to: lowerRightPoint)
path.addLine(to: lowerLeftPoint)
path.addLine(to: upperLeftPoint)
// Close the path. This will create the last line automatically.
path.close()
UIColor.red.setFill()
path.fill()
let shapeLayer = CAShapeLayer()
shapeLayer.path = path.cgPath
self.layer.mask = shapeLayer;
然而,这并不是我想要达到的目标。下面是我试图实现的目标。
我通过以下操作实现了此形状-
class Header: UIView {
var path: UIBezierPath!
override init(frame: CGRect) {
super.init(frame: frame)
self.backgroundColor = UIColor.red
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
func createHeader() {
// Drawing code
// Get Height and Width
let layerHeight = layer.frame.height
let layerWidth = layer.frame.width
// Create Path
let bezierPath = UIBezierPath()
// Points
let pointA = CGPoint(x: 0, y: 0)
let pointB = CGPoint(x: layerWidth, y: 0)
let pointC = CGPoint(x: layerWidth, y: layerHeight*2/3)
let pointD = CGPoint(x: 0, y: layerHeight)
// Draw the path
bezierPath.move(to: pointA)
bezierPath.addLine(to: pointB)
bezierPath.addLine(to: pointC)
bezierPath.addLine(to: pointD)
bezierPath.close()
// Mask to Path
let shapeLayer = CAShapeLayer()
shapeLayer.path = bezierPath.cgPath
layer.mask = shapeLayer
}
override func draw(_ rect: CGRect) {
// self.createRectangle()
self.createHeader()
}
}
也许这有帮助:对我来说很好。我在tableview单元格中使用了它
