Uibutton的标题与左侧对齐，图像与右侧

Question

当我尝试使用以下选项创建UIButton时出现问题：标题左对齐，图像右对齐，

我想以编程方式进行，这是我到目前为止所尝试的，它有效，但不是我想要

UIButton *definition_title = [UIButton buttonWithType:UIButtonTypeRoundedRect];
              definition_title.frame = CGRectMake(0,0, accordion.frame.size.width, 70.0f);
              [definition_title setImage:[UIImage imageNamed:@"image_name.png"] forState:UIControlStateNormal];
              definition_title.imageEdgeInsets = UIEdgeInsetsMake(10, 10, 10, 10);
              definition_title.imageView.contentMode = UIViewContentModeScaleAspectFit;
              [definition_title setTitle:@"Scan the Barcode" forState:UIControlStateNormal];
              definition_title.titleEdgeInsets = UIEdgeInsetsMake(0.0f, 0.0f, 0.0f, 0.0f);
              definition_title.imageEdgeInsets = UIEdgeInsetsMake(0.0f, accordion.frame.size.width-50, 0.0f, 0.0f);
              definition_title.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;

上面的代码像这样返回i Uibutton

但我希望它像这样

   |text       image|

Answer 1

方法1：

为按钮添加标题和图像，并调整标题和图像插入以使文本和图像显示在按钮的两侧

方法2：

创建UIButton的子类并覆盖func imageRect(forContentRect contentRect: CGRect) -> CGRect和func titleRect(forContentRect contentRect: CGRect) -> CGRect，并为标题和图像提供CGRect。

示例：

import UIKit

class MyTestButton: UIButton {

    override func imageRect(forContentRect contentRect: CGRect) -> CGRect {
        return CGRect(x: self.frame.maxX - contentRect.height/*specify your button width here am using height */, y: 0, width: contentRect.height/*specify your button width here am using height */, height: contentRect.height)
    }

    override func titleRect(forContentRect contentRect: CGRect) -> CGRect {
        return CGRect(x:0, y:0, width: self.bounds.size.width - self.imageRect(forContentRect:contentRect).width,height: contentRect.height)
    }
}
