发现获取cpu频率的函数iOS上并不能正常工作

    size_t size = sizeof(int);
    int results = 0;
    int mib[2] = {CTL_HW, HW_CPU_FREQ};
    int status = sysctl(mib, 2, &results, &size, NULL, 0);
    NSString *cpuFrequency = [NSString stringWithFormat:@"%d", results];
    return cpuFrequency;

这段代码
但是macos能够返回
