底层开发之越狱开发第二篇

今天项目中要用到检查iPhone是否越狱的方法。

Umeng统计的Mobclick.h里面已经包含了越狱检测的代码，可以直接使用

/*方法名:
 *        isJailbroken
 *介绍:
 *        类方法，判断设备是否越狱，判断方法根据 apt和Cydia.app的path来判断
 *参数说明:
 *        无
 *
 *
 */

#pragma mark utils api
// 类方法，判断当前设备是否已经越狱
+ (BOOL)isJailbroken;
// 类方法，判断你的App是否被破解
+ (BOOL)isPirated;

apt和Cydia的方式来进行判断的，没看见源码

然后再介绍两种方法来查看是否已经越狱，知其然知其所以然、、、

1. apt

 - (BOOL) hasAPT
 {
 return [[NSFileManager defaultManager] fileExistsAtPath:@"/private/var/lib/apt/"];
 }

2. system

 - (BOOL) successCallSystem
 {
 ) ? YES : NO;
 }

3.示例代码

 static const char* jailbreak_apps[] =

     {
         "/Applications/Cydia.app",
         "/Applications/limera1n.app",
         "/Applications/greenpois0n.app",
         "/Applications/blackra1n.app",
         "/Applications/blacksn0w.app",
         "/Applications/redsn0w.app",
         "/Applications/Absinthe.app",
         NULL,
     };

     - (BOOL) isJailBroken
     {
         // Now check for known jailbreak apps. If we encounter one, the device is jailbroken.
         ; jailbreak_apps[i] != NULL; ++i)
         {
             if ([[NSFileManager defaultManager] fileExistsAtPath:[NSString stringWithUTF8String:jailbreak_apps[i]]])
             {
                 //NSLog(@"isjailbroken: %s", jailbreak_apps[i]);
                 return YES;
             }
         }

         // TODO: Add more checks? This is an arms-race we're bound to lose.

         return NO;
     }

 @interface UIDevice (Helper)
 - (BOOL)isJailbroken;
 @end

 @implementation UIDevice (Helper)
 - (BOOL)isJailbroken {
   BOOL jailbroken = NO;
   NSString *cydiaPath = @"/Applications/Cydia.app";
   NSString *aptPath = @"/private/var/lib/apt/";
   if ([[NSFileManager defaultManager] fileExistsAtPath:cydiaPath]) {
     jailbroken = YES;
   }
   if ([[NSFileManager defaultManager] fileExistsAtPath:aptPath]) {
     jailbroken = YES;
   }
   return jailbroken;
 }
 @end
