简单实现Mac版微信防撤回简单实现Mac版微信防撤回

网上Mac微信插件有好多了,也比较成熟,更新后功能好多,
0.准备,自己下载安装theos,和insert_dylib(习惯用optool的也可以)
1.写一个tweak 就是.xm文件.hook掉MessageService的onRevokeMsg:方法(最新版微信自己使用hopper分析找到onRevokeMsg:方法,类好像换掉了)
代码如下:

%config(generator=internal)// You don't need to #include , it will be done automatically, as will // the generation of a class list and an automatic constructor.#import %hook MessageService- (void)onRevokeMsg:(id)agr { return; }// Always make sure you clean up after yourself; Not doing so could have grave consequences! %end %ctor { NSLog(@"!!!!!!---success---!!!!!!!"); }

2.一个脚本保存为insertTweak.sh文件

# #获取找到APP path=`ls | grep *.app | head -1` #找到tweak tweak=`ls | grep *.xm | head -1` temp='tempssxxxx' name=${path%.app}app_executable_backup_path="./${path}/Contents/MacOS/${name}_backup"#使用theos 的logos.pl转换,前面路径看自己theos的路径 /opt/theos/bin/logos.pl "./${tweak}" > "./${temp}.mm"#clang编译生成动态库 clang -shared -undefined dynamic_lookup -o "./${path}/Contents/MacOS/lib.dylib" "./${temp}.mm"#使用optool的就打开这个,关闭insert_dylib #optool install -c load -p @executable_path/lib.dylib -t "./${path}/Contents/MacOS/${name}"#//先复制一次备份 cp "./${path}/Contents/MacOS/${name}" "$app_executable_backup_path"#使用insert_dylib 注入生成的动态库,找到自己的insert_dylib /Users/lxmacmini/Desktop/demo/ok/insert_dylib --all-yes @executable_path/lib.dylib "$app_executable_backup_path" "./${path}/Contents/MacOS/${name}"
