没有越狱检测

问题描述

我正在尝试创建一个适用于越狱iDevices的应用程序。我已经进行了越狱检测：

I'm trying to make an app which onely works on jailbroken iDevices. I allready made a jailbreak detection:

([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"cydia://"]]);{
    UIAlertView *cydiaisinstalled=[[UIAlertView alloc]initWithTitle:@"Cydia is installed!"
                                                            message:@"You can use Respring!"
                                                           delegate:self
                                                  cancelButtonTitle:@"OK"
                                                  otherButtonTitles:nil];
    [cydiaisinstalled show];
}}

但现在我需要相反的事情。我需要一个非JAILBREAK检测。

But now I need the reverse thing. I need a NON JAILBREAK detection.

我需要你的帮助我需要这个用于Weblin。请帮助我!!!

推荐答案

尝试访问应用程序沙箱外的任何文件。例如：

Try accessing any file outside the app's sandbox. For example:

BOOL IsDeviceJailbroken(void) {
    #if TARGET_IPHONE_SIMULATOR
    return NO;
    #else
    return [[NSFileManager defaultManager] fileExistsAtPath: @"/bin/bash"];
    #endif
}

请注意安装了Cydia并拥有越狱设备是两件不同的事情。

Note that having Cydia installed and having a jailbroken device are two different things.
