iPhone是否越狱的检测方法

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
{
return (system("ls") == 0) ? YES : NO;
}

3.

  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.

        for (int i = 0; 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
