检测iOS设备上的CPU核心

#include <sys/sysctl.h>

unsigned int countCores()
{
    size_t len;
    unsigned int ncpu;

    len = sizeof(ncpu);
    sysctlbyname ("hw.ncpu",&ncpu,&len,NULL,0);

    return ncpu;
}

除此之外,您可以检查[[UIDevice currentDevice] userInterfaceI@L_83_13@m]以确定该设备是iPhone还是iPad.像这样：

if ([[UIDevice currentDevice] userInterfaceI@L_83_13@m] == UIUserInterfaceI@L_83_13@mPad) {
    NSLog(@"iPad");
}
else {
    NSLog(@"iPhone");
}
