从绘图代码显示图像答案

【问题描述】：

我有下面的示例代码，我想在 UIView 或 UIImageView 中呈现为图像。

在我的故事板上，我有一个 UIView (myUIView) 和 UIImageView (myUIImageView)。

下面的代码中缺少什么让我可以抓取代码并将其转换为图像以放置在 UIView 或 UIImageView 中？

//// General Declarations
let context = UIGraphicsGetCurrentContext()

//// Color Declarations
let fillColor = UIColor(red: 0.087, green: 0.086, blue: 0.083, alpha: 1.000)

//// Group 2
CGContextSaveGState(context)
CGContextSetAlpha(context, 0.75)
CGContextBeginTransparencyLayer(context, nil)


//// Bezier Drawing
let bezierPath = UIBezierPath()
bezierPath.moveToPoint(CGPointMake(26.08, 23.65))
bezierPath.addCurveToPoint(CGPointMake(61.71, 12.5), controlPoint1: CGPointMake(38.43, 23.65), controlPoint2: CGPointMake(54.42, 18.61))
bezierPath.addCurveToPoint(CGPointMake(52.65, 1.35), controlPoint1: CGPointMake(69, 6.38), controlPoint2: CGPointMake(64.99, 1.35))
bezierPath.addCurveToPoint(CGPointMake(16.91, 12.5), controlPoint1: CGPointMake(40.2, 1.35), controlPoint2: CGPointMake(24.2, 6.38))
bezierPath.addCurveToPoint(CGPointMake(26.08, 23.65), controlPoint1: CGPointMake(9.63, 18.61), controlPoint2: CGPointMake(13.63, 23.65))
bezierPath.closePath()
bezierPath.moveToPoint(CGPointMake(48.14, 25))
bezierPath.addLineToPoint(CGPointMake(0.79, 25))
bezierPath.addCurveToPoint(CGPointMake(0.24, 24.35), controlPoint1: CGPointMake(-0.02, 25), controlPoint2: CGPointMake(-0.21, 24.73))
bezierPath.addCurveToPoint(CGPointMake(2.41, 23.65), controlPoint1: CGPointMake(0.76, 23.92), controlPoint2: CGPointMake(1.59, 23.65))
bezierPath.moveToPoint(CGPointMake(14.36, 12.5))
bezierPath.addCurveToPoint(CGPointMake(54.26, 0), controlPoint1: CGPointMake(22.62, 5.57), controlPoint2: CGPointMake(40.59, 0))
bezierPath.addCurveToPoint(CGPointMake(64.36, 12.5), controlPoint1: CGPointMake(67.93, 0), controlPoint2: CGPointMake(72.62, 5.57))
bezierPath.addCurveToPoint(CGPointMake(37.3, 23.65), controlPoint1: CGPointMake(58.56, 17.37), controlPoint2: CGPointMake(47.81, 21.59))
bezierPath.addLineToPoint(CGPointMake(49.75, 23.65))
fillColor.setFill()
bezierPath.fill()


CGContextEndTransparencyLayer(context)
CGContextRestoreGState(context)

【解决方案1】：

创建一个派生自UIView 的新类，然后将此代码添加到drawRect 函数中。

然后将其设置为您想要的视图。

let view = NewViewClass()

太棒了。谢谢你，@marc14。
