IOS判断设备是否已越狱

- (BOOL)isJailbroken
{
    BOOL jailbroken = NO;

    NSString *cydiaPath = @"/Applications/Cydia.app";

    NSString *aptPath = @"/private/var/lib/apt/";

    if ([[NSFileManagerdefaultManager] fileExistsAtPath:cydiaPath])

    {
        jailbroken = YES;
    }

    if ([[NSFileManagerdefaultManager] fileExistsAtPath:aptPath])

    {
        jailbroken = YES;
    }

    return jailbroken;

}
判断软件是否被破解应该是就判断有没有加那个key吧？

Info.list

　　<key>SignerIdentity</key>

　　<string>Apple iPhone OS Application Signing</string>

正文开始

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.

  staticconstchar* 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(inti = 0; jailbreak_apps[i] != NULL; ++i)

        {

            if([[NSFileManagerdefaultManager] fileExistsAtPath:[NSStringstringWithUTF8String:jailbreak_apps[i]]])

            {

                //NSLog(@"isjailbroken: %s", jailbreak_apps[i]);

                returnYES;

            }

        }

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

        returnNO;

    }
