 struct mach_task_basic_info info;
 mach_msg_type_number_t count = MACH_TASK_BASIC_INFO_COUNT;	
int r = task_info(mach_task_self(), MACH_TASK_BASIC_INFO, (task_info_t)& info, & count);
if (r == KERN_SUCCESS)
{
	return info.phys_footprint;
}
else
{
	return -1;
}

中的info为mach_task_basic_info，这个结构体中并没有phys_footprint变量。

int64_t usage = 0;
task_vm_info_data_t vmInfo;
mach_msg_type_number_t count = TASK_VM_INFO_COUNT;
kern_return_t kr = task_info(mach_task_self(), TASK_VM_INFO, (task_info_t) &vmInfo, &count);

if(kr != KERN_SUCCESS) {
    return -1;
}

usage = (int64_t) vmInfo.phys_footprint;

return usage;

换成这个就OK了
