如何正确地继承UIGestureRecognizer [英] How to correctly subclass UIGestureRecognizer

问题描述

我已经阅读了文档：
http://developer.apple.com/library/ios/#documentation/EventHandling/Conceptual/EventHandlingiPhoneOS/GestureRecognizer_basics/GestureRecognizer_basics.html#//apple_ref / doc / uid / TP40009541-CH2-SW2

我正在尝试实现文档中显示的复选标记示例，我不能因为编译器显示了一些关于[super touchesMoved：touches withEvent：event]调用的警告，这是文档推荐的。

I am trying to implement the check mark example shown in the documentation and I can't because the compiler shows a bunch of warnings about the the [super touchesMoved:touches withEvent:event] call, which is recommended by the documentation.

在哪里学习如何正确学习的完整示例用于实现自定义手势的子类？

Where's the full example to learn how to correctly subclass for implementing a custom gesture?

推荐答案

我找到了WWDC 2010会话视频

I found the WWDC 2010 Session Videos

• 第120节 - 使用手势识别器简化触摸事件处理和


• 第121节 - 高级手势识别

• Session 120 - Simplifying Touch Event Handling with Gesture Recognizers and
• Session 121 - Advanced Gesture Recognition

非常有用。

要访问此视频，您必须登录 http://developer.apple.com

这里您将找到WWDC 2010的示例代码
