ios - drawRect 没有绘制正确的形状

Question

我有一个名为 TestView 的 UIView 子类，它重写了 DrawRect ，如下所示:

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()
    }
}

在我的 ViewController 上，我将此 View 作为子类添加到 View 中，如下所示:

let testView = TestView(frame: CGRectMake(0,0, 100, 100))
self.view.addSubview(testView)

但它唯一绘制的是一个白色圆圈，而不是它应该绘制的形状。

我在这里做错了什么？

Answer 1

您正在执行 UIBezierPath(ovalInRect: rect)，rect 为 100 x 100。所以我期望是一个圆圈。

如果您不想绘制圆圈，请使用 UIBezierPath() 初始化路径。

就为什么您没有看到其他内容而言，您的路径远远超出了 100 x 100 尺寸，因此我不确定您期望它呈现什么。如果您希望在 View 中渲染此路径，您应该调整这些坐标以使其落在 TestView 的大小范围内。
