在ios开发中，什么是 runtime
Runtime是iOS系统中的一个重要概念，它指的是程序运行时环境。Runtime是iOS系统的核心部分，它负责执行应用程序中的代码，并提供各种服务和资源，如内存管理、网络通信、设备访问、数据存储等。 在iOS开发中，开发者可以使用Runtime来动态地修改和检查应用程序的状态，以及执行一些在编译时无法确定的操作。例如，通过Runtime，开发者可以获取和修改类的属性和方法，检查和修改对象的状态，以及执行一些系统级别的操作，如访问设备的硬件资源、启动和停止后台任务等。 Runtime是iOS开发中不可或缺的一部分，它为开发者提供了强大的工具和资源，使得开发者能够更好地创建和管理应用程序。 [2023-11-08 00:41:15 | AI写代码神器 | 149点数解答]
