前几天，我解决了类似的问题，试试这个

private func adjustImageAndTitleOffsetsForButton (button: UIButton) {

    let spacing: CGFloat = 6.0

    let imageSize = button.imageView!.frame.size

    button.titleEdgeInsets = UIEdgeInsetsMake(0, -imageSize.width, -(imageSize.height + spacing), 0)

    let titleSize = button.titleLabel!.frame.size

    button.imageEdgeInsets = UIEdgeInsetsMake(-(titleSize.height + spacing), 0, 0, -titleSize.width)
}

为每个按钮调用此方法，如

self.adjustImageAndTitleOffsetsForButton(yourButton)

结合Ajay和Matej的回答：

import Foundation
import UIKit
class VerticalButton: UIButton {
override func awakeFromNib() {
    super.awakeFromNib()
    self.contentHorizontalAlignment = .left
}

override func layoutSubviews() {
    super.layoutSubviews()
    centerButtonImageAndTitle()
}

private func centerButtonImageAndTitle() {
    let titleSize = self.titleLabel?.frame.size ?? .zero
    let imageSize = self.imageView?.frame.size  ?? .zero
    let spacing: CGFloat = 6.0
    self.imageEdgeInsets = UIEdgeInsets(top: -(titleSize.height + spacing),left: 0, bottom: 0, right:  -titleSize.width)
    self.titleEdgeInsets = UIEdgeInsets(top: 0, left: -imageSize.width, bottom: -(imageSize.height + spacing), right: 0)
 }
}

我修改了Ajay's answer，因为我的图像没有居中：

func centerButtonImageAndTitle(button: UIButton) {
  let spacing: CGFloat = 5
  let titleSize = button.titleLabel!.frame.size
  let imageSize = button.imageView!.frame.size

  button.titleEdgeInsets = UIEdgeInsets(top: 0, left: -imageSize.width, bottom: -(imageSize.height + spacing), right: 0)
  button.imageEdgeInsets = UIEdgeInsets(top: -(titleSize.height + spacing), left: -imageSize.width/2, bottom: 0, right: -titleSize.width)
}

这是一个对我有效的解决方案。只需在storyboard中将button类设置为HorizontallyCenteredButton，并根据您的需要设置标题和图像的顶部和底部insets（将图像放置在高于标题的位置），按钮将自动调整水平insets，以便图像在标题上方居中。

class HorizontallyCenteredButton: LocalizedButton {
    override func awakeFromNib() {
        super.awakeFromNib()
        self.contentHorizontalAlignment = .left
    }

    override func layoutSubviews() {
        super.layoutSubviews()
        self.centerButtonImageAndTitle()
    }

    func centerButtonImageAndTitle() {
        let size = self.bounds.size
        let titleSize = self.titleLabel!.frame.size
        let imageSize = self.imageView!.frame.size

        self.imageEdgeInsets = UIEdgeInsets(top: self.imageEdgeInsets.top, left: size.width/2 - imageSize.width/2, bottom: self.imageEdgeInsets.bottom, right: 0)
        self.titleEdgeInsets = UIEdgeInsets(top: self.titleEdgeInsets.top, left: -imageSize.width + size.width/2 - titleSize.width/2, bottom: self.titleEdgeInsets.bottom, right: 0)
    }
}

要垂直对齐所有按钮，请首先选择按钮，然后单击脚本右下角标题为“对齐”的按钮，最后在出现的菜单中选择“垂直居中”。应该可以了。

我创建了一个视图，然后把一个VStack与图像和文本，以及按钮。确保VStack约束在所有4个侧面上都为0，以便覆盖按钮：）

如果您使用的是iOS 15.0，则可以用途：

// Create a button
let button = UIButton(type: .custom)
        
// Configure the button using UIButton.Configuration
var config = UIButton.Configuration.filled()
config.titlePadding = 10
config.imagePlacement = .top // this is whats makes the magic
config.imagePadding = 10
button.configuration = config

这是一个简单的，所以道歉，如果你已经尝试过了！
你不需要为insets设置任何东西，只要确保3个按钮与水平中心对齐即可。

选择你想要对齐的控件，点击下面高亮显示的按钮（xCode屏幕右下角），选择垂直中心选项将三个控件相互对齐，或者选择容器中的水平将它们放在视图的中间。
