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…

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…

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…

Event Handling A diagram of the architecture of this system:     HWNDMessageHandler owns the WNDPROC, and is code that is shared with the non-Aura windows build. This code is in production and "should work." On this diagram, the new classes are…

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…
