转自手势开发 IOS开发之手势——UIGestureRecognizer 共存 在 iPhone 或 iPad 的开发中,除了用 touchesBegan / touchesMoved / touchesEnded 这组方法来控制使用者的手指触控外,也可以用 UIGestureRecognizer 的衍生类別来进行判断.用 UIGestureRecognizer 的好处在于有现成的手势,开发者不用自己计算手指移动轨迹.UIGestureRecognizer的衍生类別有以下几种: UITapGes…

一个scrollview上有几个按钮在scrollview上add 了一个单击事件 singletap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];    [singletap setNumberOfTapsRequired:1];   [scrollview addGestureRecognizer:singletap];这样点击按钮,不会响应按钮的事件,直接…

UITapGestureRecognizer IOS的手势非常多, 但是特别容易其他视图起冲突的手势,要数UITapGestureRecognizer 于是有了gestureRecognizerShouldBegin:这个方法判断是否应该执行触摸事件 - (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer { BOOL flag = [super gestureRecognizerShouldBe…

当一个scene中同时有UITapGestureRecognizer和CCMenu,点击时不会响应CCMenu,此时必须对UITapGestureRecognizer进行设置 UITapGestureRecognizer *tapGestureRecognizer =[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(handleTapGestureRecognizer:)]; tapGestureRecogni…

最近在项目中用到了手势操作,键盘回收时还是挺常用的,现在总结下,多谢网络上大神们的分享. 先分享下我在项目中用的代码: UITapGestureRecognizer * mytap=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tap_gestureRecognizer:)]; [self addGestureRecognizer:mytap]; [mytap release]; //收回键盘 -(void…

首先新建一个基于Sigle view Application的项目,名为GestureTest;我的项目结构如下: 往viewController.xib文件里拖动一个imageView,并使覆盖整个屏幕,改动属性为: viewController.h文件: [cpp]viewplaincopy 1.     #import <UIKit/UIKit.h> 2. 3.     @interface ViewController : UIViewController{ 4.         IB…

ViewDidLoad中注册手势的部分代码如下: [cpp] view plaincopy UITapGestureRecognizer *oneTap = [[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hideKeyBoard)] autorelease]; oneTap.delegate = self; oneTap.numberOfTouchesRequired = ; [self.view ad…
