根据iOS 15及以上版本:

var config = UIButton.Configuration.plain() // depends on the button you want 
config.image = UIImage(named: "view_all") // set the image 
config.imagePadding = 5 // add the insets for the image 
button.configuration = config // assign the config to the button

在接口生成器中。选择UIButton -> Attributes Inspector -> Edge=Title并修改边缘插入

Riley Avron回答的一个小补充，以解释地区变化:

extension UIButton {
    func centerTextAndImage(spacing: CGFloat) {
        let insetAmount = spacing / 2
        let writingDirection = UIApplication.sharedApplication().userInterfaceLayoutDirection
        let factor: CGFloat = writingDirection == .LeftToRight ? 1 : -1

        self.imageEdgeInsets = UIEdgeInsets(top: 0, left: -insetAmount*factor, bottom: 0, right: insetAmount*factor)
        self.titleEdgeInsets = UIEdgeInsets(top: 0, left: insetAmount*factor, bottom: 0, right: -insetAmount*factor)
        self.contentEdgeInsets = UIEdgeInsets(top: 0, left: insetAmount, bottom: 0, right: insetAmount)
    }
}

我的垂直定心方法:

extension UIButton {
    
    /// Layout image and title with vertical centering.
    /// - Parameters:
    ///   - size: The button size.
    ///   - imageTopOffset: Top offset for image.
    ///   - spacing: Distance between image and title.
    func verticalAlignmentByCenter(size: CGSize, imageTopOffset: CGFloat, spacing: CGFloat) {
        let contentRect = contentRect(forBounds: CGRect(origin: .zero, size: size))
        let imageRect = imageRect(forContentRect: contentRect)
        let titleRect = titleRect(forContentRect: contentRect)

        let imageTop = imageTopOffset - imageRect.origin.y
        let imageLeft = contentRect.width/2 - imageRect.width/2
        imageEdgeInsets = UIEdgeInsets(top: imageTop, left: imageLeft, bottom: 0, right: 0)

        let titleTop = imageTopOffset + spacing + imageRect.height - titleRect.origin.y
        let titleLeft = titleRect.origin.x - contentRect.width/2 - titleRect.width/2
        titleEdgeInsets = UIEdgeInsets(top: titleTop, left: titleLeft, bottom: 0, right: 0)
    }
    
}

下面是一个如何使用imageEdgeInsets的简单示例 这将创建一个30x30的按钮，可点击区域增大10个像素(50x50)

    var expandHittableAreaAmt : CGFloat = 10
    var buttonWidth : CGFloat = 30
    var button = UIButton.buttonWithType(UIButtonType.Custom) as UIButton
    button.frame = CGRectMake(0, 0, buttonWidth+expandHittableAreaAmt, buttonWidth+expandHittableAreaAmt)
    button.imageEdgeInsets = UIEdgeInsetsMake(expandHittableAreaAmt, expandHittableAreaAmt, expandHittableAreaAmt, expandHittableAreaAmt)
    button.setImage(UIImage(named: "buttonImage"), forState: .Normal)
    button.addTarget(self, action: "didTouchButton:", forControlEvents:.TouchUpInside)

如果你想做一些类似的东西

你需要

1.为按钮设置水平和垂直对齐

Find all required values and set UIImageEdgeInsets CGSize buttonSize = button.frame.size; NSString *buttonTitle = button.titleLabel.text; CGSize titleSize = [buttonTitle sizeWithAttributes:@{ NSFontAttributeName : [UIFont camFontZonaProBoldWithSize:12.f] }]; UIImage *buttonImage = button.imageView.image; CGSize buttonImageSize = buttonImage.size; CGFloat offsetBetweenImageAndText = 10; //vertical space between image and text [button setImageEdgeInsets:UIEdgeInsetsMake((buttonSize.height - (titleSize.height + buttonImageSize.height)) / 2 - offsetBetweenImageAndText, (buttonSize.width - buttonImageSize.width) / 2, 0,0)]; [button setTitleEdgeInsets:UIEdgeInsetsMake((buttonSize.height - (titleSize.height + buttonImageSize.height)) / 2 + buttonImageSize.height + offsetBetweenImageAndText, titleSize.width + [button imageEdgeInsets].left > buttonSize.width ? -buttonImage.size.width + (buttonSize.width - titleSize.width) / 2 : (buttonSize.width - titleSize.width) / 2 - buttonImage.size.width, 0,0)];

这将在按钮上排列标题和图像。

此外，请注意更新这在每个转播

import UIKit
