At Oblong we created a self-contained iOS Drag and Drop library that can work across arbitrary views, and have made it public on github: 在Oblong，我们创建了一个独立的iOS Drag and Drop库，它可以在任意视图中工作，并在github上公开：

If you find it useful or have specific areas of enhancements you need, go ahead and let me know! 如果您发现它有用或具有您需要的特定增强功能，请继续告诉我们！

I have also made my own static library (I had no idea about OBDragDrop) 我也创建了自己的静态库（我不知道OBDragDrop）

https://github.com/jmos/JCMDragging (compile with ARC) https://github.com/jmos/JCMDragging （用ARC编译）

The library mirrors common UIKit patterns so the bulk of the interfaces are actually categories on UIKit classes: 该库镜像了常见的UIKit模式，因此大部分接口实际上是UIKit类的类别：

Dragging events are handled and forwarded by UIResponder 拖动事件由UIResponder处理和转发
Dragging events are delivered according to hitTest:withDrag: and pointInside:withDrag: 拖动事件根据hitTest传递：withDrag：和pointInside：withDrag：
Data transfer uses [UIPasteboard draggingPasteboard] and [UIResponder drag:/drop:] 数据传输使用[UIPasteboard draggingPasteboard]和[UIResponder drag：/ drop：]

The only concrete class is the gesture recogniser. 唯一具体的类是手势识别器。 There are no managers or initialisation. 没有经理或初始化。

Have a look at the sample project to see how to use it. 查看示例项目以了解如何使用它。

EDIT: I have added a readme file now. 编辑：我现在添加了自述文件。
