这就是我的工作方式:

import UIKit

func getRandomColor() -> UIColor {
    let randomRed:CGFloat = CGFloat(drand48())
    let randomGreen:CGFloat = CGFloat(drand48())
    let randomBlue:CGFloat = CGFloat(drand48())
    return UIColor(red: randomRed, green: randomGreen, blue: randomBlue, alpha: 1.0)
}

let standardFrame = CGRect(x: 0, y: 0, width: 200, height: 40)
let rootView = UIView(frame: standardFrame)
rootView.backgroundColor = UIColor.blueColor()

let views = [UIView(), UIView(), UIView()]

for view in views {
    view.backgroundColor = getRandomColor()
    view.bounds.size = CGSize(width: 40, height: 40)
}

let stack = UIStackView(frame: CGRect(x: 0, y: 0, width: 200, height: 40))
stack.backgroundColor = UIColor.redColor()

stack.addArrangedSubview(views[0])
stack.addArrangedSubview(views[1])
stack.addArrangedSubview(views[2])

stack.axis = .Horizontal
stack.alignment = .Fill
stack.distribution = .FillEqually
stack.spacing = 5

rootView.addSubview(stack)
