本文详细介绍了如何通过PBXProject对象在Unity-iPhone项目中设置目标属性、添加框架、修改Info.plist，并强调了操作完成后必须写回文件的重要性。

一、获取 PBXProject PBXProject的很多操作都是通过guid的

var pbxProject = new PBXProject();

二、获取projectPath

var projectPath = PBXProject.GetPBXProjectPath(iosProjectPath);

三、读取pbxProject 文件

pbxProject.ReadFromFile(projectPath);

四、读取Unity-iPhone"对应的target和UnityFramework

GetUnityMainTargetGuid是获取XCode工程中"Unity-iPhone"对应的target，GetUnityFrameworkTargetGuid则对应"UnityFramework"

var mainTargetGuid = pbxProject.GetUnityMainTargetGuid();//

//这个对应target中的Unity-iPhone
var frameworkTargetGuid = pbxProject.GetUnityFrameworkTargetGuid();//

//这个对应target中UnityFramework

五、添加

pbxProject.AddBuildProperty(mainTargetGuid, "OTHER_LDFLAGS", "-ObjC");
pbxProject.AddBuildProperty(frameworkTargetGuid, "OTHER_LDFLAGS", "-ObjC");

pbxProject.SetTeamId(mainTargetGuid, "");
pbxProject.SetTeamId(frameworkTargetGuid, "");
pbxProject.SetBuildProperty(mainTargetGuid, "ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES", "YES");
pbxProject.SetBuildProperty(frameworkTargetGuid, "ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES", "NO");

pbxProject.SetBuildProperty(mainTargetGuid, "GCC_ENABLE_OBJC_EXCEPTIONS", "YES");
pbxProject.SetBuildProperty(frameworkTargetGuid, "GCC_ENABLE_OBJC_EXCEPTIONS", "YES");

pbxProject.SetBuildProperty(mainTargetGuid, "GCC_C_LANGUAGE_STANDARD", "gnu11");
pbxProject.SetBuildProperty(frameworkTargetGuid, "GCC_C_LANGUAGE_STANDARD", "gnu11");

pbxProject.AddFrameworkToProject(frameworkTargetGuid, "Photos.framework", false);

 // info.plist 设置
            var plistPath = Path.Combine(iosProjectPath, "Info.plist");
            var plist = new PlistDocument();
            plist.ReadFromString(File.ReadAllText(plistPath, Encoding.ASCII));
            plist.root.values.Add("NSPhotoLibraryUsageDescription", new PlistElementString("We will use this permission if the child sends lessons and feedback through the album."));
            plist.root.values.Add("ITSAppUsesNonExemptEncryption", new PlistElementBoolean(false));
            AddPlistElementDict(plist,"NSAppTransportSecurity","NSAllowsArbitraryLoads",new PlistElementBoolean(true));

六、操作完后要写回文件，否则无效

File.WriteAllText(plistPath, plist.WriteToString());

七、总结

string pbxProjectPath = PBXProject.GetPBXProjectPath(path);
        pbxProject = new PBXProject();
        pbxProject.ReadFromString(File.ReadAllText(pbxProjectPath));
        mainTarget = pbxProject.GetUnityMainTargetGuid();//这个对应target中的Unity-iPhone
        frameworkTarget = pbxProject.GetUnityFrameworkTargetGuid();//这个对应target中UnityFramework
        //...
        //你的操作
        //...
　　　　 pbxProject.WriteToFile(pbxProjectPath);　　//操作完后要写回文件，否则无效
