UIGestureRecognizerDelegate

Regulating Gesture Recognition

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer//Asks the delegate if a gesture recognizer should begin interpreting touches.
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch//Ask the delegate if a gesture recognizer should receive an object representing a touch.

Controlling Simultaneous Gesture Recognition

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer

Setting Up Failure Requirements

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRequireFailureOfGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldBeRequiredToFailByGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer

iOS 手势及触摸

转自:http://justsee.iteye.com/blog/1885538 一.响应链在IOS开发中会遇到各种操作事件,通过程序可以对这些事件做出响应. 首先,当发生事件响应时,必须知道由谁来响应事件.在IOS中,由响应者链来对事件进行响应,所有事件响应的类都是UIResponder的子类, 响应者链是一个由不同对象组成的层次结构,其中的每个对象将依次获得响应事件消息的机会.当发生事件时,事件首先被发送给第一响应者,第一响应者往往是事件发生的视图,也就是用户触摸屏幕的地方.事件将沿着响

关于backBarButtonItem的N种方法

今天在做项目的时候遇到一点小问题,后来自己解决了,也顺便思考了一下更深层次的东西,在这里分享一下~~ 替换返回按钮的文字很多app的要求所有的返回按钮的title都是“返回”,如果上一层题目文字太多,下一层的返回按钮文字就会显示不完全,而且这样可以使软件显得整洁. 方法一: 最普通的想法,A界面的navigationItem.backBarButtonItem修改的是B(A的下一级)界面的返回按钮,所以可以写一个BaseViewController,让所有的UIViewController继承
