Ios iPhone UIButton 图像位置

发布于11月15日

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

[ (>) Explore the app ]

但我需要把这UIImage放在文本后面:

[ Explore the app (>) ]

我怎样才能把UIImage移到右边？

推荐答案

这是我自己做这件事的方法，(after about 10 years)

来自UIButton的子类(Button，因为我们生活在SWIFT时代)
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
        }
    }
}
