我这边测试了下，使用上述方式在 iOS 上确实拿不到 CPU 频率，而拿不到的主要是因为通过 sysctl 系统调用在 MacOS 和 iOS 平台上的获取系统信息的底层实现是通过内核变量的 MIB（管理信息库）来访问导出的内核变量，但是出于安全性的考虑，MIB 有些内核变量在这几个版本的 iOS 上禁止访问这些内核变量，比如你上面提到的 HW_CPU_FREQ 就是其中之一，类似的还有 cpufrequency_max 和 cpufrequency_min，但是网上还有很多代码是通过这种方式在较老版本上成功获取到，包括我文章提到手淘上也用这种方式，应该都是遗留代码。
那还有什么其他方式获取 CPU 主频呢？其实可以通过两种方式。
第一种方式比较简单，是采取硬编码的方式，在 App 中建立一张 CPU 主频的映射表，然后根据用户的机型去这张映射表中找出即可。
单位为 MHZ
static const NSUInteger CPUFrequencyTable[] = {
[iPhone_1G] = 412,
[iPhone_3G] = 620,
[iPhone_3GS] = 600,
[iPhone_4] = 800,
[iPhone_4_Verizon] = 800,
[iPhone_4S] = 800,
[iPhone_5_GSM] = 1300,
[iPhone_5_CDMA] = 1300,
[iPhone_5C] = 1000,
[iPhone_5S] = 1300,
[iPhone_6] = 1400,
[iPhone_6_Plus] = 1400,
[iPhone_6S] = 1850,
[iPhone_6S_Plus] = 1850,
[iPod_Touch_1G] = 400,
[iPod_Touch_2G] = 533,
[iPod_Touch_3G] = 600,
[iPod_Touch_4G] = 800,
[iPod_Touch_5] = 1000,
[iPad_1] = 1000,
[iPad_2_CDMA] = 1000,
[iPad_2_GSM] = 1000,
[iPad_2_WiFi] = 1000,
[iPad_3_WiFi] = 1000,
[iPad_3_GSM] = 1000,
[iPad_3_CDMA] = 1000,
[iPad_4_WiFi] = 1400,
[iPad_4_GSM] = 1400,
[iPad_4_CDMA] = 1400,
[iPad_Air] = 1400,
[iPad_Air_Cellular] = 1400,
[iPad_Air_2] = 1500,
[iPad_Air_2_Cellular] = 1500,
[iPad_Pro] = 2260,
[iPad_Mini_WiFi] = 1000,
[iPad_Mini_GSM] = 1000,
[iPad_Mini_CDMA] = 1000,
[iPad_Mini_2] = 1300,
[iPad_Mini_2_Cellular] = 1300,
[iPad_Mini_3] = 1300,
[iPad_Mini_3_Cellular] = 1300,
[iUnknown] = 0
};
第二种方式是自己通过运算来得出 CPU 的时钟频率
extern int freqTest(int cycles);
static double GetCPUFrequency(void)
{
volatile NSTimeInterval times[500];
int sum = 0;
for(int i = 0; i < 500; i++)
{
times[i] = [[NSProcessInfo processInfo] systemUptime];
sum += freqTest(10000);
times[i] = [[NSProcessInfo processInfo] systemUptime] - times[i];
}
NSTimeInterval time = times[0];
for(int i = 1; i < 500; i++)
{
if(time > times[i])
time = times[i];
}
double freq = 1300000.0 / time;
return freq;
}
其中 freqTest 这个函数是用汇编写的，在工程加入一个文件 cpuFreq.s，后缀 s 代表这个文件是一个汇编文件，文件的代码如下：

当然这个汇编文件只支持 armv7 和 armv7s，也就是 32 位 Arch，64位汇编指令没给出，如果你使用的是 64 位机器调试，记得将 build archive architecture only 设置为 NO，否则会编译不通过，如下图：
我这边用一台 iPhone 6 测试了这种方法获得 CPU 频率，结果为 1391614727.725209 HZ，大约也就是 1400 MHZ，和上面那张表中主频一致。

能否解释下为什么是用：double freq = 1300000.0 / time;来计算CPU频率呢？
我知道了，汇编中用了130条add指令，而每次执行10000次，所以1300000除以耗时即得频率了

大佬 请问你这边解决了这个release环境的问题吗？

@BestZedXiao 老弟,release 会有问题,啊应该不会吧,我就打了个.a,不同arch引用不同汇编,

@BestZedXiao 确实有问题,你那边有什么结果了没? 结果一直是0

@waiwaib 我都试了 跟32位 64位 没啥关系 跟这个汇编方法 的环境应该的有关系吧 暂时还没有弄出来呢

@BestZedXiao 我去真机看一下release log

@BestZedXiao 已经解决,是测试cpu的汇编操作寄存器的时候把栈内容改动了.导致结果数组内容错误

@BestZedXiao 我建议你降低优化等级.我发现我前面的问题解决了 又出现了莫名的问题, 这个问题的根源是编译器的优化导致的,

@waiwaib @BestZedXiao 我这里也是把optimization level 降为none的

我的主要目的 是想获取系统所有安装APP 的启动时间，或者说运行时间 我现在的想法是获取系统进程详细信息，从中获取时间

@iamqk @BestZedXiao 另外的解决release情况下code generation optimization level导致出现问题可能方案 1.剔除掉被打乱的测试数据(已验证,可正确运行于10余测试设备,但是不能确保万一用户设备出现问题) 2.使用C函数来代替汇编进行测试,(需要时间去测试各个设备的运行时间是否一致) ..其他未知~

@waiwaib 1. code generation optimization level 这个在64位的静态库的工程设置就行了，应该对调用的工程没有什么影响，即调用工程的code generation optimization level可以正常设置，具体你设置code generation optimization level后产生的是什么新问题呢？ 2.用汇编不用c函数就是因为c函数最后也是编译成汇编的，但是编译后的准确度肯定不如直接使用汇编

@iamqk 1.还是不行,我测试了重新打.a,静态库工程code generation optimization level 设置为none,调用工程还是会有问题,产生的问题是跑测试的汇编会打乱volatile NSTimeInterval times[500]的值,最开始我改用new 来在堆上分配array空间,结果...导致整个函数内部都不能分配内存, 2.因为我怀疑是汇编这块被编译器优化导致问题,所以想试试用C函数来测试看看~

@iamqk 目前我还是采用的剔除被打乱的数据,因为你存了结果后,测试的汇编又在下次运行一顿操作寄存器什么的,,,数据就被抹除重写了之类..导致测试结果不正确
