Gesture Recognizers 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 interpret tou…

一.Gesture Recognizers Gesture Recognizers是在iOS3.2引入的,可以用来识别手势.简化定制视图事件处理的对象.Gesture Recognizers的基类为UIGestureRecognizer,这一个抽象基类,定义了实现底层手势识别行为的编程接口.在UIKit框架中提供了6个具体的手势识别类,用来识别常见的手势.这6个手势识别器类为: UITapGestureRecognizer:用来识别点击手势,包括单击,双击,甚至三击等.UIPinchGestur…

Gesture Recognizers与触摸事件分发 通过一个问题引出今天的知识: 1.大家应该都遇见过 当需要给tableView 添加一个tap 手势识别 但是tableView 的上的事件(滑动...)还不影响,这时候应该怎么做呢? 答:应该设置tap.cancelsTouchesInView = NO; (看完下面的解释因该就知道为什么了) 一.Gesture Recognizers Gesture Recognizers是在iOS3.2引入的,可以用来识别手势.简化定制视图事件处理的对…

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…

Views Because view objects are the main way your application interacts with the user, they have many responsibilities. Here are just a few: 通过view对象是与用户交互的主要方式,它们有很多责任,下面是其中一些: Layout and subview management   布局 A view defines its own default resizin…

前言:我的第一篇文章荼菜的iOS笔记–Core Animation 核心动画算是比较详细讲了核心动画的用法,但是如你上篇看到的,有时我们只是想实现一些很小的动画,这时再用coreAnimation就会觉得麻烦,不用慌,苹果工程师爸爸们已经为我们给UIView封装好了一些coreAnimationBlock,足以满足平时的动画需求. 动画Block1 1 2 3 4 5 6 7 8 9 10 /* 参数1: Duration: 动画持续时间 参数2: delay: 延迟时间 参数3: option…

先谈谈在开发中遇到的手势问题: 今天在开发android程序时,在 View.OnTouchListener 的 onTouch(View view, MotionEvent motionEvent) 方法中建立GestureDetector 和 相应的 GestureDetector.OnGestureListener,目的是在 GestureDetector.OnGestureListener 的 onLongPress 方法中移动 onTouch 参数中的view.但是发现这种方法根本不好…
