unity-iPhoneX适配

iPhoneX适配，比较搓的一种方式，在不修改分辨率（720 x 1280）的情况下适配

iphone X 主屏尺寸： 5.8英寸 主屏分辨率： 2436 x 1125

---

核心代码

修改 工程目录/Classes/UnityAppController.mm 文件

判断的方式比较搓，以 iPhone X 的宽高的 与众不同来判断

为了不调整分辨率的情况下适配（这里是 竖屏 应用），高度改为 150 是最好的值。（横屏 应用修改 height 为 width，y为 x 即可）

• 找到方法

  

• 代码

  //    _window         = [[UIWindow alloc] initWithFrame: [UIScreen mainScreen].bounds];
  
      CGRect winSize = [UIScreen mainScreen].bounds;
      if (winSize.size.height / winSize.size.width > 2) {
          winSize.size.height -= 150;
          winSize.origin.y = 75;
          ::printf("-> is iphonex hello world\n");
      } else {
          ::printf("-> is not iphonex hello world\n");
      }
      _window = [[UIWindow alloc] initWithFrame: winSize];

自动化修改代码

不用每次打xcode后都需要手动修改

参考：https://www.cnblogs.com/pandawuwyj/p/6904770.html

1. 增加一个修改 文件的类

   using UnityEngine;
   using System.Collections;
   using System.Collections.Generic;
   using System.IO;
   
   namespace UnityEditor.XCodeEditor
   {
      public partial class XClassExt : System.IDisposable
      {
   
          private string filePath;
   
          public XClassExt(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 == -1)
              {
                  Debug.LogError(filePath + " not found sign in " + below);
                  return;
              }
   
              int endIndex = text_all.LastIndexOf("\n", beginIndex + below.Length);
   
              text_all = text_all.Substring(0, 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 == -1)
              {
                  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()
          {
   
          }
      }
   }
   

2. 打包后处理，动态修改 xcode配置 及 文件内容

   using System;
   using System.IO;
   using System.Collections.Generic;
   using UnityEditor;
   using UnityEngine;
   using UnityEditor.Callbacks;
   
   #if UNITY_EDITOR_OSX
   
   using UnityEditor.iOS.Xcode;
   using UnityEditor.XCodeEditor;
   
   #endif
   
   
   public class Package {
   
   
   #if UNITY_EDITOR_OSX
   
      [PostProcessBuildAttribute(100)]
      public static void OnPostProcessBuild(BuildTarget target, string pathToBuiltProject) {
          if (target != BuildTarget.iOS) {
              Debugger.LogWarning("Target is not iPhone. XCodePostProcess will not run");
              return;
          }
          // Create a new project object from build target
          PBXProject project = new PBXProject();
          string configFilePath = PBXProject.GetPBXProjectPath(pathToBuiltProject);
          project.ReadFromFile(configFilePath);
          string targetGuid = project.TargetGuidByName("Unity-iPhone");
          string debug = project.BuildConfigByName(targetGuid, "Debug");
          string release = project.BuildConfigByName(targetGuid, "Release");
          project.AddBuildPropertyForConfig(debug, "CODE_SIGN_RESOURCE_RULES_PATH", "$(SDKROOT)/ResourceRules.plist");
          project.AddBuildPropertyForConfig(release, "CODE_SIGN_RESOURCE_RULES_PATH", "$(SDKROOT)/ResourceRules.plist");
   
          project.AddFrameworkToProject(targetGuid, "SystemConfiguration.framework", true);
          project.AddFrameworkToProject(targetGuid, "Security.framework", true);
          project.AddFrameworkToProject(targetGuid, "libz.tbd", true);
          project.AddFrameworkToProject(targetGuid, "libc++.tbd", true);
   
          project.SetBuildProperty(targetGuid, "ENABLE_BITCODE", "NO");
   
          project.WriteToFile(configFilePath);
   
          EditSuitIpXCode(pathToBuiltProject);
      }
   
      public static void EditSuitIpXCode(string path) {
          //插入代码
          //读取UnityAppController.mm文件
          string src = @"_window         = [[UIWindow alloc] initWithFrame: [UIScreen mainScreen].bounds];";
          string dst = @"//    _window         = [[UIWindow alloc] initWithFrame: [UIScreen mainScreen].bounds];
   
      CGRect winSize = [UIScreen mainScreen].bounds;
      if (winSize.size.height / winSize.size.width > 2) {
          winSize.size.height -= 150;
          winSize.origin.y = 75;
          ::printf(""-> is iphonex aaa hello world\n"");
      } else {
          ::printf(""-> is not iphonex aaa hello world\n"");
      }
      _window = [[UIWindow alloc] initWithFrame: winSize];
   
      ";
   
          string unityAppControllerPath = path + "/Classes/UnityAppController.mm";
          XClassExt UnityAppController = new XClassExt(unityAppControllerPath);
          UnityAppController.Replace(src, dst);
      }
   
   #endif
   
   }
