NSProcessInfo对象是用来获取进程的相关信息，包括进程的参数、PID、进程所在的系统的主机名、操作系统名、操作系统版本等等。(UIDevice获设备信息)

 

    @autoreleasepool {
        //创建一个NSProcessInfo对象，表示当前进程
        NSProcessInfo *processInfo = [NSProcessInfo processInfo];
        
        //获取运行该进程的参数
        NSArray *arr = [processInfo arguments];
        NSLog(@"运行该程序的参数为：%@", arr);
        //获取该进程的进程标示符
        NSLog(@"该程序的进程标示符(PID)为：%d", [processInfo processIdentifier]);
        //获取该进程的进程名
        NSLog(@"该程序的进程名为：%@", [processInfo processName]);
        //设置该进程的新进程名
        [processInfo setProcessName:@"test"];
        NSLog(@"该程序的新进程名为：%@", [processInfo processName]);
        
        //获取运行该进程的系统的环境变量
        NSLog(@"运行该进程的系统的所有环境变量为：%@", [processInfo environment]);
        //获取运行该进程的主机名
        NSLog(@"运行该进程的主机名为：%@", [processInfo hostName]);
        //获取运行该进程的操作系统
        NSLog(@"运行该进程所在的操作系统为：%ld", [processInfo operatingSystem]);
        //获取运行该进程的操作系统的版本
        NSLog(@"运行该进程所在的操作系统名为：%@", [processInfo operatingSystemName]);
        //获取运行该进程的操作系统的版本
        NSLog(@"运行该进程所在的操作系统的版本为：%@", [processInfo operatingSystemVersionString]);
        
        //获取运行该进程的系统的物理内存
        NSLog(@"运行该进程的系统的物理内存为：%lld", [processInfo physicalMemory]);
        //获取运行该进程的系统的处理器数量
        NSLog(@"运行该进程的系统的处理器数量为：%ld", [processInfo processorCount]);
        //获取运行该进程的系统的处于激活状态的处理器数量
        NSLog(@"运行该进程的系统的处于激活状态的处理器数量为：%ld", [processInfo activeProcessorCount]);
        //获取运行该进程的系统已运行的时间
        NSLog(@"运行该进程的系统的已运行时间为：%f", [processInfo systemUptime]);
    }
