我在iOS 15中遇到了一个问题，当设置图像到右角不工作，而在iOS 15之前，它是正常工作。
我想实现的目标：

我的成就：

下面是我在iOS 15中使用的完整代码：

import UIKit

class ViewController: UIViewController { 

    override func viewDidLoad() {
        super.viewDidLoad()
        let btnDropdown = getDropdownButton()
        btnDropdown.translatesAutoresizingMaskIntoConstraints = false
        view.addSubview(btnDropdown)
        NSLayoutConstraint.activate([
            btnDropdown.heightAnchor.constraint(equalToConstant: 44),
            btnDropdown.leadingAnchor.constraint(equalTo: view.layoutMarginsGuide.leadingAnchor),
            btnDropdown.trailingAnchor.constraint(equalTo: view.layoutMarginsGuide.trailingAnchor),
            btnDropdown.topAnchor.constraint(equalTo: view.layoutMarginsGuide.topAnchor, constant: 30)
        ])
    }

    fileprivate func getDropdownButton() -> UIButton {
        var button: UIButton!
        if #available(iOS 15.0, *),
           let btnConfig = getButtonConfiguration() {
            button = UIButton(configuration: btnConfig)
        } else {
            button = UIButton(type: .custom)
        }
        button.setTitle("Select Tags", for: .normal)
        setupGeneralSettings(for: button)
        return button
    }

    fileprivate func setupGeneralSettings(for button: UIButton) {
        button.titleEdgeInsets = UIEdgeInsets(top: 0, left: 8, bottom: 0, right: 8)
        button.contentEdgeInsets = UIEdgeInsets(top: 0, left: 8, bottom: 0, right: 8)
        button.contentHorizontalAlignment = .left
        button.layer.borderWidth = 1
        button.layer.cornerRadius = 8
        button.clipsToBounds = true
        button.backgroundColor = .lightGray.withAlphaComponent(0.3)
        button.titleLabel?.font = UIFont.systemFont(ofSize: 14, weight: .medium)
        button.setTitleColor(UIColor.black, for: .normal)
    }

    @available(iOS 15.0, *)
    fileprivate func getButtonConfiguration() -> UIButton.Configuration? {
        var btnConfig = UIButton.Configuration.plain()
        btnConfig.buttonSize = .medium
        btnConfig.titleAlignment = .leading
        btnConfig.imagePlacement = .trailing
        btnConfig.image = UIImage(systemName: "arrowtriangle.down.circle")
        btnConfig.contentInsets = NSDirectionalEdgeInsets(top: 0, leading: 8, bottom: 0, trailing: 8)
        btnConfig.titleTextAttributesTransformer = UIConfigurationTextAttributesTransformer { incoming in
            var outgoing = incoming
            outgoing.font = UIFont.systemFont(ofSize: 14, weight: .medium)
            return outgoing
        }
        return btnConfig
    }
}

**注意：**当我说iOS 15时，我的意思是我正在使用UIButton.配置，因为UIButton的titleEdgeInset、imageEdgeInset和contentEdgeInset在iOS 15中已被弃用。此外，我认为UIButton.配置中缺少了一些东西，通过该配置，图像将到达按钮的右边缘，但我不确定是什么。

如果您还需要其他信息，请告诉我。
