iPhone UIButton - 图像位置

问题描述

我有一个 UIButton 带有文本探索应用程序"和 UIImage (>)在 Interface Builder 中它看起来像:

I have a UIButton with text "Explore the app" and UIImage (>) In Interface Builder it looks like:

[ (>) Explore the app ]

但我需要将这个 UIImage 放在文本之后:

But I need to place this UIImage AFTER the text:

[ Explore the app (>) ]

如何将 UIImage 向右移动?

推荐答案

这是我自己的做法，(大约 10 年后)

1. UIButton 的子类(按钮，因为我们生活在 Swift 时代)
2. 将图像和标签放入堆栈视图.

class CustomButton: Button {

    var didLayout: Bool = false // The code must be called only once

    override func layoutSubviews() {
        super.layoutSubviews()
        if !didLayout, let imageView = imageView, let titleLabel = titleLabel {
            didLayout = true
            let stack = UIStackView(arrangedSubviews: [titleLabel, imageView])
            addSubview(stack)
            stack.edgesToSuperview() // I use TinyConstraints library. You could handle the constraints directly
            stack.axis = .horizontal
        }
    }
}
