了解Cocoa框架类之间继承关系
From: http://www.zhujiangroad.com/program/iOS/24545.html
Cocoa框架类之间继承关系是本文要介绍的内容，主要是来了解cocoa的继承关系，Cocoa框架包含两个核心框架:Foundation和Application Kit (UIKit) 框架 。
在Cocoa开发中是必要的,至于其它框架(如：Core Data、Sync Services、Address Book、Preference Panes、Screen Saver、Web Kit)则是辅助和可选的；Foundation框架和Application Kit框架的区分标准在于用户界面 。
如果一个对象既不出现在用户界面上，也不是专门用于支持用户界面,那么它就属于Foundation框架,命令行工具和Internet服务器就是这样的例子 。
Foundation类层次的根是NSObject类，它（和NSObject及NSCopying协议一起）定义了基本的对象属性和行为 。
Foundation框架的剩余部分由几组相互关联的类和一些独立的类组成 。有一些代表基本数据类型的类，如字符串、字节数组；用于存储其它对象的集合类；一些代表系统信息的类，如日期类；还有一些代表系统实体的类，比如端口、线程、和进程 。
Application Kit (UIKit) 框架包含实现图形的、事件驱动的用户界面需要的所有对象：窗口、对话框、按键、菜单、滚动条、文本输入框—这个列表还在不断增加 。Application Kit由超过125个类和协议组成 。
所有的类最终都从Foundation框架的NSObject类继承而来, Application Kit帮助您处理所有的细节，它可以高效地进行屏幕描画、和营建设备及屏幕缓冲区进行通讯，在描画之前清除屏幕上的区域，以及对视图进行裁剪 。
iPhone按照视图加入的先后顺序，由后向前显示，这说明了视图层次是一种空间上的叠加关系 。

Intent intent = new Intent();
intent.setAction(com.android.phone.EmergencyDialer.DIAL);
startActivity(intent);

startActivity(it);
String body=”this is sms demo”;
Intent mmsintent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts(“smsto”, number, null));
mmsintent.putExtra(Messaging.KEY_ACTION_SENDTO_MESSAGE_BODY, body);
mmsintent.putExtra(Messaging.KEY_ACTION_SENDTO_COMPOSE_MODE, true);
