检测iphone设备是否越狱

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;
}
return jailbroken;
}
@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。
