判断手机是否root或越狱

给客户开发的app通过第三方检测机构检测出来一些漏洞，其中一项判断手机是否root或者越狱，如果是的话需要加提示，从网上找了一些方法，修改一下用到了项目中

1. 判断Android手机是否root

   //在app的入口activity的onCreate方法中添加如下一段代码
   if (CommonUtil.checkRoot()) {
       new AlertDialog.Builder(this)
               .setTitle("当前设备已ROOT，存在安全风险，请更换其他设备")
               .setMessage("")
               .setPositiveButton("退出应用", new DialogInterface.OnClickListener() {
                   @Override
                   public void onClick(DialogInterface dialog, int which) {
                       System.exit(0);//退出app
                   }
               })
               .setCancelable(false)
               .show();
   }
   //判断是否root方法
   public static boolean checkRoot() {
       boolean isRoot = false;
       String buildTags = Build.TAGS;
       if (buildTags!=null && buildTags.contains("test-keys")) {
           isRoot = true;
       }
   
       String[] paths = { "/system/app/Superuser.apk", "/sbin/su", "/system/bin/su", "/system/xbin/su", "/data/local/xbin/su", "/data/local/bin/su", "/data/local/su" };
       for (String path : paths) {
           if (new File(path).exists()) isRoot = true;
       }
       return isRoot;
   }
   

2. 判断iOS手机是否越狱

   //在AppDelegate的didFinishLaunchingWithOptions中添加下面代码
   BOOL isBroken = [self checkJailbreaking];
   if (isBroken) [self showJailbreakingAlert];
   //检测是否越狱
   - (BOOL)checkJailbreaking {
       BOOL isBroken = NO;
       
       struct stat stat_info;
       if (0 == stat("/Applications/Cydia.app", &stat_info)) {
           isBroken = YES;
       }
       
       int ret ;
       Dl_info dylib_info;
       int (*func_stat)(const char *, struct stat *) = stat;
       if ((ret = dladdr(func_stat, &dylib_info))) {
           if (strcmp(dylib_info.dli_fname,"/usr/lib/system/libsystem_kernel.dylib") != 0) {
               isBroken = YES;
         }
       }
       
       char *env = getenv("DYLD_INSERT_LIBRARIES");
       if (env) isBroken = YES;
       
       return isBroken;
   }
   //弹出提示框
   - (void)showJailbreakingAlert {
       UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"当前设备已ROOT，存在安全风险，请更换其他设备" message:@"" preferredStyle:UIAlertControllerStyleAlert];
       UIAlertAction *cancel = [UIAlertAction actionWithTitle:@"退出应用" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {
           exit(0);
       }];
       [alert addAction:cancel];
       [self.window.rootViewController presentViewController:alert animated:YES completion:NULL];
   }
