如何在swift中製作像下圖一樣的標籤

Question

我已經在聊天應用程序上工作，並且我嘗試製作標籤，像波紋管圖像，但是我做不到任何人都可以幫助我。

Answer 1

在Xcode中去你的資產，選擇您的泡沫圖像，然後單擊show slicing。

切片使您的圖像可以與給定切片一起拉伸而不會變形。

使用CoreGraphics繪製此表格很複雜。我已經實現了這個不完美的結果。您可以在「drawRect」方法中使用此代碼，並且在繪製（或覆蓋佈局）文本之後。

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() 
} 

，我建議你在Illustrator中創建的圖像或一些其他的程序與此表格，並把它作爲背景。
