简单来说就是unity提供一套api去修改xcode项目工程配置以及修改plist文件内容(当unity build结束后, 会自动回调OnPostProcessBuild).
以下是一些用到的配置处理：
ENABLE_BITCODE
AddFramework
https
NSPhotoLibraryUsageDescription
[PostProcessBuild]
public static void OnPostprocessBuild(BuildTarget BuildTarget, string path)
{
if (BuildTarget == BuildTarget.iOS)
{
UnityEngine.Debug.Log("XCodePostProcess: Starting to perform post build tasks for iOS platform."); /*======== projPath ========*/
string projPath = path + "/Unity-iPhone.xcodeproj/project.pbxproj"; PBXProject proj = new PBXProject();
proj.ReadFromFile(projPath); string target = proj.TargetGuidByName("Unity-iPhone"); // ENABLE_BITCODE=False
proj.SetBuildProperty(target, "ENABLE_BITCODE", "false"); // add extra framework(s)
proj.AddFrameworkToProject(target, "Security.framework", false);
proj.AddFrameworkToProject(target, "CoreTelephony.framework", true);
proj.AddFrameworkToProject(target, "libz.tbd", true); // rewrite to file
File.WriteAllText(projPath, proj.WriteToString()); string plistPath = path + "/Info.plist";
PlistDocument plist = new PlistDocument();
plist.ReadFromString(File.ReadAllText(plistPath)); // Get root
PlistElementDict rootDict = plist.root; /* ipad 关闭分屏 */
rootDict.SetBoolean("UIRequiresFullScreen", true); var now = System.DateTime.Now;
string time = string.Format("{0}_{1}_{2} {3}:{4}:{5}", now.Year, now.Month, now.Day, now.Hour, now.Minute, now.Second);
/* 设置Build值 */
rootDict.SetString("CFBundleVersion", string.Format("{0}({1})", GlobalVars.VERSION, time)); /* iOS9所有的app对外http协议默认要求改成https */
// Add value of NSAppTransportSecurity in Xcode plist
var atsKey = "NSAppTransportSecurity"; PlistElementDict dictTmp = rootDict.CreateDict( atsKey );
dictTmp.SetBoolean( "NSAllowsArbitraryLoads", true); // location native development region
rootDict.SetString("CFBundleDevelopmentRegion", "zh_CN"); // for share sdk 截屏
rootDict.SetString("NSPhotoLibraryUsageDescription", "We need use photo library usage"); // Write to file
File.WriteAllText(plistPath, plist.WriteToString()); }
}
在Info.plist里添加URL Scheme：
/*======== plist ========*/
string plistPath = path + "/Info.plist";
PlistDocument plist = new PlistDocument();
plist.ReadFromString(File.ReadAllText(plistPath)); // Get root
PlistElementDict rootDict = plist.root; // URL schemes 追加
var urlTypeArray = plist.root.CreateArray("CFBundleURLTypes");
var urlTypeDict = urlTypeArray.AddDict();
urlTypeDict.SetString("CFBundleTypeRole", "Editor");
urlTypeDict.SetString("CFBundleURLName", "OpenApp");
var urlScheme = urlTypeDict.CreateArray("CFBundleURLSchemes");
urlScheme.AddString("sampleApp"); urlTypeDict = urlTypeArray.AddDict();
urlTypeDict.SetString("CFBundleURLName", "com.abc.sampleApp");
urlScheme = urlTypeDict.CreateArray("CFBundleURLSchemes");
urlScheme.AddString("sampleApp2");
有些第三方的sdk需要在appController里加一些“料”，比如Adjust SDK的deeplink功能，需要在openUrl里加[Adjust appWillOpenUrl:url];，也需要在continueUserActivity函数里作相应处理。这里的处理参考了雨松大大的博客。
首先是XClass这个类：
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System.IO; namespace UnityEditor.XCodeEditor
{
public partial class XClass : System.IDisposable
{ private string filePath; public XClass(string fPath)
{
filePath = fPath;
if (!System.IO.File.Exists(filePath))
{
Debug.LogError(filePath + "not found in path.");
return;
}
} public void WriteBelow(string below, string text)
{
StreamReader streamReader = new StreamReader(filePath);
string text_all = streamReader.ReadToEnd();
streamReader.Close(); int beginIndex = text_all.IndexOf(below);
if (beginIndex == -)
{
Debug.LogError(filePath + " not found sign in " + below);
return;
} int endIndex = text_all.LastIndexOf("\n", beginIndex + below.Length); text_all = text_all.Substring(, endIndex) + "\n" + text + "\n" + text_all.Substring(endIndex); StreamWriter streamWriter = new StreamWriter(filePath);
streamWriter.Write(text_all);
streamWriter.Close();
} public void Replace(string below, string newText)
{
StreamReader streamReader = new StreamReader(filePath);
string text_all = streamReader.ReadToEnd();
streamReader.Close(); int beginIndex = text_all.IndexOf(below);
if (beginIndex == -)
{
Debug.LogError(filePath + " not found sign in " + below);
return;
} text_all = text_all.Replace(below, newText);
StreamWriter streamWriter = new StreamWriter(filePath);
streamWriter.Write(text_all);
streamWriter.Close(); } public void Dispose()
{ }
}
}
然后还是在OnPostprocessBuild里进行hack：
string xcodePath = Path.GetFullPath (path);
UnityEditor.XCodeEditor.XClass UnityAppController = new UnityEditor.XCodeEditor.XClass(xcodePath + "/Classes/UnityAppController.mm");
UnityAppController.WriteBelow("#include \"PluginBase/AppDelegateListener.h\"", "#include \"Adjust.h\"");
UnityAppController.WriteBelow("AppController_SendNotificationWithArg(kUnityOnOpenURL, notifData);","[Adjust appWillOpenUrl:url];");
UnityAppController.WriteBelow("SensorsCleanup();\n}", "- (BOOL)application:(UIApplication*)application continueUserActivity:(nonnull NSUserActivity *)userActivity restorationHandler:(nonnull void (^)(NSArray * _Nullable))restorationHandler\r{\rif ([[userActivity activityType] isEqualToString:NSUserActivityTypeBrowsingWeb])\r{\rNSURL *url = [userActivity webpageURL];\rNSURL *oldStyleDeepLink = [Adjust convertUniversalLink:url scheme:@\"sampleApp\"];\r[Adjust appWillOpenUrl:url];\r}\rreturn YES;\r}");
还在研究怎么加XCode Entitlement文件中。。。
