How to set PBXProject

I tried the following methods and they all showed the same error message.

Code (CSharp):

1. string proPath = $"{pathBuildProject}/Unity-iPhone.xcodeproj/project.pbxproj";
2. PBXProject pbx = new PBXProject();
3. pbx.ReadFromString(File.ReadAllText(proPath));
4. string targetGuid = PBXProject.GetUnityTargetName();
5. pbx.SetBuildProperty(targetGuid, "PRODUCT_NANE", "Name");
6. string proPath = $"{pathBuildProject}/Unity-iPhone.xcodeproj/project.pbxproj";
7. PBXProject pbx = new PBXProject();
8. pbx.ReadFromFile(proPath);
9. string targetGuid = PBXProject.GetUnityTargetName();
10. pbx.SetBuildProperty(targetGuid, "PRODUCT_NANE", "Name");

Error content: NullReferenceException: Object reference not set to an instance of an object UnityEditor.iOS.Xcode.PBXProject.GetConfigListForTarget (System.String targetGuid) (at /Users/builduser/buildslave/unity/build/External/XcodeAPI/Xcode/PBXProject.cs:1225) UnityEditor.iOS.Xcode.PBXProject.SetBuildProperty (System.String targetGuid, System.String name, System.String value) (at /Users/builduser/buildslave/unity/build/External/XcodeAPI/Xcode/PBXProject.cs:1326)

 

Had to change my code to this for it to work (Unity 2019.3.13f1 and Xcode 11.4.1), to accommodate with the GetUnityMainTargetGuid() and build configs changes.
Check that you set "PRODUCT_NAME" as well (instead of PRODUCT_NANE)

Code (CSharp):

1. // Get the project file
2. string projPath = pathToBuiltProject + "/Unity-iPhone.xcodeproj/project.pbxproj";
3. PBXProject proj = new PBXProject();
4. proj.ReadFromString(File.ReadAllText(projPath));
5. string target = proj.GetUnityMainTargetGuid();
6.  
7. // Change the project's name
8. var configNames = proj.BuildConfigNames();
9. foreach(var configName in configNames)
10. {
11.     var config = proj.BuildConfigByName(target, configName);
12.     proj.SetBuildPropertyForConfig(config, "PRODUCT_NAME", "Name");
13. }
14.  
15. // Write the changes
16. File.WriteAllText(projPath, proj.WriteToString());

 

thank you~
