我有一个名为UIView的{{1}}子类，其覆盖范围为TestView：
DrawRect在我import Foundation
import UIKit
class TestView: UIView {
override func drawRect(rect: CGRect) {
let rectangle5Color = UIColor(red: 1.000, green: 1.000, blue: 1.000, alpha: 1.000)
let rectangle5StrokeColor = UIColor(red: 1.000, green: 1.000, blue: 1.000, alpha: 1.000)
let rectangle5Path = UIBezierPath(ovalInRect: rect)
rectangle5Path.moveToPoint(CGPoint(x: 758, y: 1467))
rectangle5Path.addLineToPoint(CGPoint(x: 748, y: 1467))
rectangle5Path.addLineToPoint(CGPoint(x: 204, y: 1467))
rectangle5Path.addLineToPoint(CGPoint(x: 204, y: 1205))
rectangle5Path.addCurveToPoint(CGPoint(x: 266, y: 1205), controlPoint1: CGPoint(x: 204, y: 1205), controlPoint2: CGPoint(x: 248.33, y: 1205))
rectangle5Path.addCurveToPoint(CGPoint(x: 754, y: 1135), controlPoint1: CGPoint(x: 411.79, y: 1205), controlPoint2: CGPoint(x: 627.68, y: 1135))
rectangle5Path.addLineToPoint(CGPoint(x: 758, y: 1135))
rectangle5Path.addCurveToPoint(CGPoint(x: 1232, y: 1205), controlPoint1: CGPoint(x: 884.32, y: 1135), controlPoint2: CGPoint(x: 1086.21, y: 1205))
rectangle5Path.addCurveToPoint(CGPoint(x: 1296, y: 1205), controlPoint1: CGPoint(x: 1233.67, y: 1205), controlPoint2: CGPoint(x: 1296, y: 1205))
rectangle5Path.addLineToPoint(CGPoint(x: 1296, y: 1467))
rectangle5Path.addLineToPoint(CGPoint(x: 758, y: 1467))
rectangle5Path.closePath()
rectangle5Path.moveToPoint(CGPoint(x: 752.5, y: 1009))
rectangle5Path.addCurveToPoint(CGPoint(x: 867, y: 1122.5), controlPoint1: CGPoint(x: 815.74, y: 1009), controlPoint2: CGPoint(x: 867, y: 1059.82))
rectangle5Path.addCurveToPoint(CGPoint(x: 752.5, y: 1236), controlPoint1: CGPoint(x: 867, y: 1185.18), controlPoint2: CGPoint(x: 815.74, y: 1236))
rectangle5Path.addCurveToPoint(CGPoint(x: 638, y: 1122.5), controlPoint1: CGPoint(x: 689.26, y: 1236), controlPoint2: CGPoint(x: 638, y: 1185.18))
rectangle5Path.addCurveToPoint(CGPoint(x: 752.5, y: 1009), controlPoint1: CGPoint(x: 638, y: 1059.82), controlPoint2: CGPoint(x: 689.26, y: 1009))
rectangle5Path.closePath()
rectangle5Color.setFill()
rectangle5Path.fill()
rectangle5StrokeColor.setStroke()
rectangle5Path.lineWidth = 5
rectangle5Path.stroke()
}
}
上我将此视图作为子类添加到视图中：
ViewController但它唯一能画出一个白色圆圈而不是它应该绘制的形状。
我在这里做错了什么？
答案 0 :(得分：0)
你正在UIBezierPath(ovalInRect: rect)，rect为100 x 100.所以我希望有一个圆圈。
如果您不想绘制圆圈，请改为使用UIBezierPath()初始化路径。
就你没有看到任何其他东西的原因而言，你的路径远远超出了100 x 100的尺寸，所以我不确定你想要渲染的是什么。如果您希望它在视图中呈现此路径，则应将这些坐标调整为TestView的大小。
