如何在swift中制作像下图一样的标签

Question

我已经在聊天应用程序上工作，并且我尝试制作标签，像波纹管图像，但是我做不到任何人都可以帮助我。

Answer 1

在Xcode中去你的资产，选择您的泡沫图像，然后单击show slicing。

切片使您的图像可以与给定切片一起拉伸而不会变形。

使用CoreGraphics绘制此表格很复杂。我已经实现了这个不完美的结果。您可以在“drawRect”方法中使用此代码，并且在绘制（或覆盖布局）文本之后。

func drawCanvas1(frame: CGRect = CGRect(x: 0, y: 0, width: 120, height: 100)) { 
    //// General Declarations 
    // This non-generic function dramatically improves compilation times of complex expressions. 
    func fastFloor(_ x: CGFloat) -> CGFloat { return floor(x) } 

    //// Rectangle Drawing 
    let rectanglePath = UIBezierPath(roundedRect: CGRect(x: frame.minX + fastFloor(frame.width * 0.25000 + 0.5), y: frame.minY + fastFloor(frame.height * 0.00000 + 0.5), width: fastFloor(frame.width * 1.00000 + 0.5) - fastFloor(frame.width * 0.25000 + 0.5), height: fastFloor(frame.height * 1.00000 + 0.5) - fastFloor(frame.height * 0.00000 + 0.5)), cornerRadius: 10) 
    UIColor.gray.setFill() 
    rectanglePath.fill() 


    //// Bezier 3 Drawing 
    let bezier3Path = UIBezierPath() 
    bezier3Path.move(to: CGPoint(x: frame.minX + 0.5, y: frame.minY + 85.5)) 
    bezier3Path.addCurve(to: CGPoint(x: frame.minX + 30.5, y: frame.minY + 64.5), controlPoint1: CGPoint(x: frame.minX + 0.5, y: frame.minY + 85.5), controlPoint2: CGPoint(x: frame.minX + 30.5, y: frame.minY + 85.5)) 
    bezier3Path.addCurve(to: CGPoint(x: frame.minX + 43.5, y: frame.minY + 99.5), controlPoint1: CGPoint(x: frame.minX + 30.5, y: frame.minY + 43.5), controlPoint2: CGPoint(x: frame.minX + 43.5, y: frame.minY + 99.5)) 
    bezier3Path.move(to: CGPoint(x: frame.minX + 0.59, y: frame.minY + 85.5)) 
    bezier3Path.addCurve(to: CGPoint(x: frame.minX + 43.5, y: frame.minY + 99.5), controlPoint1: CGPoint(x: frame.minX - 0.43, y: frame.minY + 86.43), controlPoint2: CGPoint(x: frame.minX + 6.72, y: frame.minY + 99.5)) 
    UIColor.gray.setFill() 
    bezier3Path.fill() 
    UIColor.gray.setStroke() 
    bezier3Path.lineWidth = 1 
    bezier3Path.lineCapStyle = .round 
    bezier3Path.lineJoinStyle = .round 
    bezier3Path.stroke() 
} 

，我建议你在Illustrator中创建的图像或一些其他的程序与此表格，并把它作为背景。
