有没有办法在运行时识别 iOS 设备 CPU 架构?
谢谢。
最佳答案
你可以使用 sysctlbyname :
#include <sys/types.h>
#include <sys/sysctl.h>
#include <mach/machine.h>
NSString *getCPUType(void)
{
NSMutableString *cpu = [[NSMutableString alloc] init];
size_t size;
cpu_type_t type;
cpu_subtype_t subtype;
size = sizeof(type);
sysctlbyname("hw.cputype", &type, &size, NULL, 0);
size = sizeof(subtype);
sysctlbyname("hw.cpusubtype", &subtype, &size, NULL, 0);
// values for cputype and cpusubtype defined in mach/machine.h
if (type == CPU_TYPE_X86)
{
[cpu appendString:@"x86 "];
// check for subtype ...
} else if (type == CPU_TYPE_ARM)
{
[cpu appendString:@"ARM"];
switch(subtype)
{
case CPU_SUBTYPE_ARM_V7:
[cpu appendString:@"V7"];
break;
// ...
}
}
return [cpu autorelease];
}
