使用NSSortDescriptor类对NSArray数组中的数据按照规则排序。-NSArray Class NSSortDescriptor use of the data in an array sorted in accordance with the rules.

模拟操作系统的进程调用-simulated the process of operating system calls

调试程序使其在读者优先模式下可以运行并且能实现基本的功能得出正确的结果：能够实现读写互斥，写写互斥，读读不互斥，一个进程结束能够唤醒等待队列中的进程（先读者队列后写着队列）完善功能：由用户决定写者向缓冲区中写入的内容，读者能够读出并显示出来；当缓冲区中没有数据时，读者要等待，直到缓冲区中有数据才能读根据“读者优先”加以改变，增加一个“写者优先”模式，并且由用户来选择模式

本次程序的题目为：进程管理――支持多个进程并发运行的简单的进程管理模拟系统，对本实验的分析要求是：⑴系统中的同步机构采用信号量上的P、V操作的机制；⑵控制机构包括阻塞和唤醒操作；⑶时间片中断处理程序处理模拟的时间片中断；⑷进程调度程序负责为各进程分配处理机；⑸根据用户的需求来创建n个进程(n为即满足用户需求,又不超出系统可容的最大进程数),各进程互斥地访问使用临界资源 S1、S2；⑹使用动态优先数(如：随阻塞次数的增加而减小优先数，以提高其优先权)；⑺进程结束后应能够撤消；⑻进程间能实现“发送”和“接收”两个消息缓冲通信操作；⑼系统在运行过程中随机打印出各进程的状态变换过程、系统的调度过程及公共变量的变化情况，在一个进程运行完毕，进入完成状态后，可以将该进程撤消，也可以动态的创建另一个新的进程。-the procedures on the topic of : process management-- to support multiple concurrent processes running a simple process management simulation system for the analysis of the experimental requirements are : 1 system of institutions using synchronous signals on the amount of P, V operation of the mechanism; 2 control agencies, including obstruction and awaken operation ; 3-time interrupt handling procedures-time simulation of interruption; 4 process scheduler is responsible for the allocation process processors; together according to the user"s needs to create process n (n that meet user needs, without exceeding the system can accommodate
