iOS Event Handling

学习目的

客户端程序中需要和用户的交互，而如果要在程序中对用户的点击等事件进行有效响应，就需要了解下iOS的Event Handling处理。 ## 具体内容 ### 事件类型 iOS系统中有三种类型的事件，Touch，Motion和RemoteControl：

typedef enum {
	UIEventTypeTouches,
	UIEventTypeMotion,
	UIEventTypeRemoteControl,
} UIEventType;

其中每种类型又有子类型：

typedef enum {
	UIEventSubtypeNone                              = 0,
 
	UIEventSubtypeMotionShake                       = 1,
 
	UIEventSubtypeRemoteControlPlay                 = 100,
	UIEventSubtypeRemoteControlPause                = 101,
	UIEventSubtypeRemoteControlStop                 = 102,
	UIEventSubtypeRemoteControlTogglePlayPause      = 103,
	UIEventSubtypeRemoteControlNextTrack            = 104,
	UIEventSubtypeRemoteControlPreviousTrack        = 105,
	UIEventSubtypeRemoteControlBeginSeekingBackward = 106,
	UIEventSubtypeRemoteControlEndSeekingBackward   = 107,
	UIEventSubtypeRemoteControlBeginSeekingForward  = 108,
	UIEventSubtypeRemoteControlEndSeekingForward    = 109,
} UIEventSubtype;
