检测ios设备是否越狱

如何查看是否越狱？最简单的方法就是查看你设备上是否多了越狱的目录
detectDevice.h

@interface UIDevice (Helper) 

-(BOOL)isJailbroken; 

@end

detectDevice.m

@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; 

    } 

    returnjailbroken; 

} 

@end

然后在你代码中调用[UIDevice currentDevice] isJailbroken], 如果返回YES说明被破解了，为NO，则没被破解
