如何制作水平滚动视图和其中的一些按钮(编程) [英] How to make Horizontal scrollView and some buttons in it (programming)

问题描述

对不起，我有问题.我不使用StoryBoard.

我想要这样一个视图.

请帮助我. 谢谢大家！

解决方案

我尝试了您的代码，并对其进行了一些更改.除非您有其他事情发生，否则它会按预期工作:

var scView:UIScrollView!
let buttonPadding:CGFloat = 10
var xOffset:CGFloat = 10

override func viewDidLoad() {
    super.viewDidLoad()
    scView = UIScrollView(frame: CGRect(x: 0, y: 120, width: view.bounds.width, height: 50))
    view.addSubview(scView)

    scView.backgroundColor = UIColor.blue
    scView.translatesAutoresizingMaskIntoConstraints = false

    for i in 0 ... 10 {
        let button = UIButton()
        button.tag = i
        button.backgroundColor = UIColor.darkGray
        button.setTitle("\(i)", for: .normal)
        //button.addTarget(self, action: #selector(btnTouch), for: UIControlEvents.touchUpInside)

        button.frame = CGRect(x: xOffset, y: CGFloat(buttonPadding), width: 70, height: 30)

        xOffset = xOffset + CGFloat(buttonPadding) + button.frame.size.width
        scView.addSubview(button)


    }

    scView.contentSize = CGSize(width: xOffset, height: scView.frame.height)
}

sorry,I have a problem.I don't use storyBoard.

I want to make a view like this.

but I try to do this. Finlly,scrollView just show last button like this.

This is code:

var scView:UIScrollView = UIScrollView()
var buttonPadding:CGFloat = 10
var xOffset:CGFloat = 10


scView.backgroundColor = UIColor.blue
scView.translatesAutoresizingMaskIntoConstraints = false


func viewDidLoad() {

for i in 0 ... 10 {

    let button = UIButton()

    button.tag = i
    button.backgroundColor = UIColor.darkGray
    button.setTitle("\(i)", for: .normal)
    button.addTarget(self, action: #selector(btnTouch), for: UIControlEvents.touchUpInside)

    button.frame = CGRect(x: xOffset, y: CGFloat(buttonPadding), width: 70, height: 30)

    xOffset = xOffset + CGFloat(buttonPadding) + button.frame.size.width
    scView.addSubview(button)


}

scView.contentSize = CGSize(width: xOffset, height: scView.frame.height)

}

please help me. Thanks all!

解决方案

I have tried your code and changed it a bit. It works as expected, unless you have something other going on:

var scView:UIScrollView!
let buttonPadding:CGFloat = 10
var xOffset:CGFloat = 10

override func viewDidLoad() {
    super.viewDidLoad()
    scView = UIScrollView(frame: CGRect(x: 0, y: 120, width: view.bounds.width, height: 50))
    view.addSubview(scView)

    scView.backgroundColor = UIColor.blue
    scView.translatesAutoresizingMaskIntoConstraints = false

    for i in 0 ... 10 {
        let button = UIButton()
        button.tag = i
        button.backgroundColor = UIColor.darkGray
        button.setTitle("\(i)", for: .normal)
        //button.addTarget(self, action: #selector(btnTouch), for: UIControlEvents.touchUpInside)

        button.frame = CGRect(x: xOffset, y: CGFloat(buttonPadding), width: 70, height: 30)

        xOffset = xOffset + CGFloat(buttonPadding) + button.frame.size.width
        scView.addSubview(button)


    }

    scView.contentSize = CGSize(width: xOffset, height: scView.frame.height)
}
