写在前面 最近的一个iOS App项目中遇到了这么问题:通过App访问服务器的大多数资源不需要登录,但是访问某些资源是需要用户提供验证的,一般来说,通常App的做法(譬如美团App)将这些资源放在“我的”模块,在未登录情况下,当点击“我的”某个模块时,以modally给出一个界面用于登录,我不晓得美团是怎么实现的:但在我看来,比较优雅的方式是在网络底层实现“modally呈现登录界面”,具体来说,当用户欲访问“我的购物券”时,在网络访问层发现用户未登录,就弹出一个登陆界面,用户登录成功后,就将这…

Event Delivery: The Responder Chain 事件传递:响应链 When you design your app, it’s likely that you want to respond to events dynamically. For example, a touch can occur in many different objects onscreen, and you have to decide which object you want to resp…

Gesture Recognizers 手势识别器 Gesture recognizers convert low-level event handling code into higher-level actions. They are objects that you attach to a view, which allows the view to respond to actions the way a control does. Gesture recognizers interpr…

About Events in iOS Users manipulate their iOS devices in a number of ways, such as touching the screen or shaking the device. iOS interprets when and how a user is manipulating the hardware and passes this information to your app. The more your app…

基本概念: 加速计: 又称加速度计,测量设备运动的加速度. 加速度: 矢量,描绘速度的方向和大小变化的快慢. 陀螺仪: 感测与维持方向的装置. 原文: Motion Event声明: 由于本人水平有限,翻译定有不当甚至错误之处,如有发现还望指出. 当用户移动,摇晃,或倾斜设备时,产生motion事件.这些motion事件被设备硬件检测到,就是加速计和陀螺仪. acclerometer事实上是由3个加速计组成,X,Y,Z坐标轴各有一个.每一个测量随着时间的推移以线性的速度变化.结合这三个加速计可以…

事件是发送给应用程序来通知它用户动作的对象.在iOS中,事件可以有多种形式:多触摸事件,motion(,移动,手 势)事件---例如,设备的加速计(accelerometer)--和控制多媒体的事件.(最后一种类型的事件被称为一个远程控制事件因为它起始于一个 耳机或其他外部访问配件).如下图所示: 在iOS中,UIKit和Core Motion框架负责事件传播和投递. 一.事件类型和投递:一 个iPhone.iPad或者iPod touch设备有多种方式集成输入流数据给应用程序访问.多触摸技术直…

A delegate is a type that safely encapsulates a method, similar to a function pointer in C and C++. Unlike C function pointers, delegates are object-oriented, type safe, and secure. The type of a delegate is defined by the name of the delegate. The f…

What is an Event? Change in the state of an object is known as event i.e. event describes the change in state of source. Events are generated as result of user interaction with the graphical user interface components. For example, clicking on a butto…

根据现在的理解,我把event处理分为5部分,第一是,Event处理的Architecture:第二是,Event的Dispatch到first responder之前: 第三是,Event从first responder出来后:第四是,Action与Event的关系:第五是,Apple Event的处理. 1. Event Handling Architecture 下面这张图解释了在MacOSX上event处理的过程. Before it dispatches an event to an…

当我们设计app的时候,我们很可能想动态的响应事件.例如,触摸一个拥有许多不同对象的屏幕,你要决定给哪个对象一个响应事件,怎么样对象接收到事件. 当一个用户产生事件发生时(如 点击),UIKit产生一个对象,这个包含要被处理的对象的信息.接着把事件对象放到active app's(一个application对象,负责初始化用户事件路由.从全局管理一个运行的application)事件队列中.对于触摸事件,这个对象是一组触摸,打包放在UIEvent对象.对motion事件而言,事件对象根据你使用框…

JavaScript has several built-in ways of reacting to user interaction and other events. To make a page dynamic and responsive, we need to harness this capability so that we can, at the appropriate times, use the jQuery techniques we have learned so fa…

The Event System 在Qt中,事件是继承了虚拟类QEvent的对象,它代表了程序所发生的事情或者程序需要知道的一个外部活动的结果.事件可以被任意 QObject子类的实例接收和处理,是与widgets密切相关.本文描述了在一个典型的程序中事件是如何被传送和处理的. How Events are Delivered 当发生一个事件,Qt通过构造一个适当的 QEvent子类的实例来创建事件对象来代表它,并通过调用vevent()函数把它传送到特定的 QObject 实例. 该函数本身不…

1. 前言 在C语言i中,存储变量的结构体加上一组函数指针,大概就可以算是一个对象模型了:如果将一组函数指针捆绑为结构体, 后期根据配置或者环境需要绑定到不同实现模块中的一组函数,可以认为是C语言面对对象的设计实现了. 2. 概述 事件模型,定义在"libgusterfs/src/"下几个文件中: event.h // 事件模型的接口定义:各个结构体的定义 event.c // 实现了最基本的模型的管理相关的函数eventpool.c // pool模式 具体的实现eventepoll…
