我通过将它放入 – (void)viewDidLoad进行测试

- (void)viewDidLoad {
    [super viewDidLoad];

    int mib[4];
    size_t bufSize = 0;
    int local_error = 0;
    struct kinfo_proc kp;

    mib[0] = CTL_KERN;
    mib[1] = KERN_PROC;
    mib[2] = KERN_PROC_PID;
    mib[3] = getpid();

    bufSize = sizeof (kp);
    if ((local_error = sysctl(mib,4,&kp,&bufSize,NULL,0)) < 0) {
        label.text = @"Failure calling sysctl";
        return;
    }
    if (kp.kp_proc.p_flag & P_TRACED)
        label.text = @"I am traced";
    else
        label.text = @"I am not traced";
}
