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

1 - (BOOL) hasAPT
2 {
3 return [[NSFileManager defaultManager] fileExistsAtPath:@"/private/var/lib/apt/"];
4 }

2. system

1 - (BOOL) successCallSystem
2 {
3 return (system("ls") == 0) ? YES : NO;
4 }

 

3.示例代码

 1 static const char* jailbreak_apps[] =
 2 
 3     {
 4         "/Applications/Cydia.app",
 5         "/Applications/limera1n.app",
 6         "/Applications/greenpois0n.app",
 7         "/Applications/blackra1n.app",
 8         "/Applications/blacksn0w.app",
 9         "/Applications/redsn0w.app",
10         "/Applications/Absinthe.app",
11         NULL,
12     };
13      
14     - (BOOL) isJailBroken
15     {
16         // Now check for known jailbreak apps. If we encounter one, the device is jailbroken.
17         for (int i = 0; jailbreak_apps[i] != NULL; ++i)
18         {
19             if ([[NSFileManager defaultManager] fileExistsAtPath:[NSString stringWithUTF8String:jailbreak_apps[i]]])
20             {
21                 //NSLog(@"isjailbroken: %s", jailbreak_apps[i]);
22                 return YES;
23             }
24         }
25          
26         // TODO: Add more checks? This is an arms-race we're bound to lose.
27          
28         return NO;
29     }
30  
31 
32 @interface UIDevice (Helper)  
33 - (BOOL)isJailbroken;  
34 @end
35 
36 @implementation UIDevice (Helper)  
37 - (BOOL)isJailbroken {  
38   BOOL jailbroken = NO;  
39   NSString *cydiaPath = @"/Applications/Cydia.app";  
40   NSString *aptPath = @"/private/var/lib/apt/";  
41   if ([[NSFileManager defaultManager] fileExistsAtPath:cydiaPath]) {  
42     jailbroken = YES;  
43   }  
44   if ([[NSFileManager defaultManager] fileExistsAtPath:aptPath]) {  
45     jailbroken = YES;  
46   }  
47   return jailbroken;  
48 }  
49 @end
