.NET MAUI - iOS：如何在运行时获取证书信息？

Question

我有一个MAUI应用程序，在构建ipa文件并使用证书对其进行签名后，我想在运行时获取证书的信息（例如字节数组格式的证书），请告诉我该怎么做？非常感谢

我发现这个代码使用安全框架来获取证书，但是没有找到 SecStaticCode 和 SecCodeSigner 2 个类。

using System;
using System.Linq;
using Foundation;
using UIKit;
using Security;

public partial class ViewController : UIViewController
{
    public ViewController(IntPtr handle) : base(handle) { }

    public override void ViewDidLoad()
    {
        base.ViewDidLoad();
        // Perform any additional setup after loading the view, typically from a nib.

        // Get the main application bundle
        NSBundle mainBundle = NSBundle.MainBundle;

        // Get the IPA path
        string ipaPath = mainBundle.BundlePath;

        // Get the digital signature data for the IPA file
        NSData signatureData = NSData.FromFile(ipaPath + "/_CodeSignature/CodeResources");

        // Create an instance of the Security framework's SecStaticCode class
        var staticCode = new SecStaticCode(ipaPath);

        // Get the signing information
        SecCodeSigner signer = staticCode.SigningInformation;

        // Get the list of certificates used to sign the IPA
        SecCertificate[] certificates = signer.SigningCertificates;

        if (certificates != null && certificates.Length > 0)
        {
            //Get the first certificate(you can iterate through all if there are multiple)
            SecCertificate certificate = certificates.First();

            //Get the certificate data
            NSData certificateData = certificate.GetEncoded();

            //You can now use the certificate information as needed
            Console.WriteLine("IPA Certificate: " + certificateData.ToString());
        }
    }
}
