从Unity到iOS，如何完美自动化框架、设置和plist？

Question

在 Unity3D 中构建到 iOS Xcode 项目时，

如何完美地自动化所有三个

• 构架，
• 设置，
• plist项目？

解决方案必须只有最现代的 2019 语法和变体，因为这些年来 Unity 中的这一点略有变化。

Answer 1

对于 2019 年...

文件名，BuildPostProcessor.cs

把它放在文件夹 Assets/Editor/ 中。 （如果它不存在，只需将文件夹“Editor/”准确地放在那里。）

这展示了如何完成所有三个框架、设置和 plist。

// filename BuildPostProcessor.cs
// put it in a folder Assets/Editor/
using System.IO;
using UnityEngine;
using UnityEditor;
using UnityEditor.Callbacks;
using UnityEditor.iOS.Xcode;

public class BuildPostProcessor {

    [PostProcessBuild]
    public static void ChangeXcodePlist(BuildTarget buildTarget, string path) {

        if (buildTarget == BuildTarget.iOS) {

            string plistPath = path + "/Info.plist";
            PlistDocument plist = new PlistDocument();
            plist.ReadFromFile(plistPath);

            PlistElementDict rootDict = plist.root;

            Debug.Log(">> Automation, plist ... <<");

            // example of changing a value:
            // rootDict.SetString("CFBundleVersion", "6.6.6");

            // example of adding a boolean key...
            // < key > ITSAppUsesNonExemptEncryption </ key > < false />
            rootDict.SetBoolean("ITSAppUsesNonExemptEncryption", false);

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

    [PostProcessBuildAttribute(1)]
    public static void OnPostProcessBuild(BuildTarget target, string path) {

        if (target == BuildTarget.iOS) {

            PBXProject project = new PBXProject();
            string sPath = PBXProject.GetPBXProjectPath(path);
            project.ReadFromFile(sPath);

            string tn = PBXProject.GetUnityTargetName();
            string g = project.TargetGuidByName(tn);

            ModifyFrameworksSettings(project, g);

            // modify frameworks and settings as desired
            File.WriteAllText(sPath, project.WriteToString());
        }
    }

    static void ModifyFrameworksSettings(PBXProject project, string g) {

        // add hella frameworks

        Debug.Log(">> Automation, Frameworks... <<");

        project.AddFrameworkToProject(g, "blah.framework", false);
        project.AddFrameworkToProject(g, "libz.tbd", false);

        // go insane with build settings

        Debug.Log(">> Automation, Settings... <<");

        project.AddBuildProperty(g,
            "LIBRARY_SEARCH_PATHS",
            "../blahblah/lib");

        project.AddBuildProperty(g,
            "OTHER_LDFLAGS",
            "-lsblah -lbz2");

        // note that, due to some Apple shoddyness, you usually need to turn this off
        // to allow the project to ARCHIVE correctly (ie, when sending to testflight):
        project.AddBuildProperty(g,
            "ENABLE_BITCODE",
            "false");
    }

}

这样就可以了。

注意 - 拼图的最后一部分是跨文件复制（可能是数据文件或文本文件）。 实际上，最好只使用“StreamingAssets/”方法，在本 QA 中有完整的解释。

Unity 2019.3 的固定代码：

// filename BuildPostProcessor.cs
// put it in a folder Assets/Editor/
using System.IO;
using UnityEngine;
using UnityEditor;
using UnityEditor.Callbacks;
using UnityEditor.iOS.Xcode;

public class BuildPostProcessor
{

    [PostProcessBuild]
    public static void ChangeXcodePlist(BuildTarget buildTarget, string path)
    {

        if (buildTarget == BuildTarget.iOS)
        {

            string plistPath = path + "/Info.plist";
            PlistDocument plist = new PlistDocument();
            plist.ReadFromFile(plistPath);

            PlistElementDict rootDict = plist.root;

            Debug.Log(">> Automation, plist ... <<");

            // example of changing a value:
            // rootDict.SetString("CFBundleVersion", "6.6.6");

            // example of adding a boolean key...
            // < key > ITSAppUsesNonExemptEncryption </ key > < false />
            rootDict.SetBoolean("ITSAppUsesNonExemptEncryption", false);

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

    [PostProcessBuildAttribute(1)]
    public static void OnPostProcessBuild(BuildTarget target, string path)
    {

        if (target == BuildTarget.iOS)
        {

            PBXProject project = new PBXProject();
            string sPath = PBXProject.GetPBXProjectPath(path);
            project.ReadFromFile(sPath);

            string g = project.GetUnityFrameworkTargetGuid();

            ModifyFrameworksSettings(project, g);

            // modify frameworks and settings as desired
            File.WriteAllText(sPath, project.WriteToString());
        }
    }

    static void ModifyFrameworksSettings(PBXProject project, string g)
    {

        // add hella frameworks

        Debug.Log(">> Automation, Frameworks... <<");

        project.AddFrameworkToProject(g, "blah.framework", false);
        project.AddFrameworkToProject(g, "libz.tbd", false);

        // go insane with build settings

        Debug.Log(">> Automation, Settings... <<");

        project.AddBuildProperty(g,
            "LIBRARY_SEARCH_PATHS",
            "../blahblah/lib");

        project.AddBuildProperty(g,
            "OTHER_LDFLAGS",
            "-lsblah -lbz2");

        // note that, due to some Apple shoddyness, you usually need to turn this off
        // to allow the project to ARCHIVE correctly (ie, when sending to testflight):
        project.AddBuildProperty(g,
            "ENABLE_BITCODE",
            "false");
    }
