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;
}

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;
}
