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];

• 运行效果

自动化修改代码

不用每次打xcode后都需要手动修改​

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()
       {

       }
   }
}

1. 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

using UnityEditor.iOS.Xcode;
using UnityEditor.XCodeEditor;

#endif


public class Package {


#if

   [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
