除非用户用的是字符串 ‘scroll-ended’

用户不会用到的，因为事件传递出来的是EventType.AUTOSCROLL_ENDED，是数字
| 'scroll-ended-with-threshold' : EventType.AUTOSCROLL_ENDED_WITH_THRESHOLD | ||
| 'scroll-ended-with-threshold' : EventType.AUTOSCROLL_ENDED_WITH_THRESHOLD, | ||
| 'scroll-began': EventType.SCROLLING_BEGAN, | ||
| 'scroll-ended': EventType.SCROLLING_ENDED |

请把新增的事件补充到 event 注释区域中，在这个文件的最下面，你搜索 @event touch-up 就能看到
| * !#zh 滚动视图滚动结束的时候发出的事件 | ||
| * @property {Number} SCROLLING_ENDED | ||

请问什么时候需要区分 AUTOSCROLL_ENDED 和 SCROLLING_ENDED？

在没有触发惯性滚动的时候 就需要用SCROLLING_ENDED来通知滚动结束

滚动有2种结束方式，1种是立即结束1种就是需要惯性滚动一段距离后结束，这里的2个事件就是用来对应这2种操作

那把这两个事件合并为一个 SCROLL_ENDED 就行了吧？

这个就要看具体需求了。毕竟这里是2种状态，分成2个事件也是有他的价值的

好像不对啊，判断是否要继续加载，应该是监听 scrolling 事件吧？因为只要有在滚动，不论是用户手指在拖拽还是自动滚动，都需要继续加载内容。

就先合并这两个事件吧，统一叫 SCROLL_ENDED 就好，之后要是有遇到合理的需求再拆分。事件名称保持不变，还是叫做 scroll-ended，只不过之前是自动滚动停止时才触发，现在是不自动滚动的话，手动停止滚动也触发。

这样会带来一个问题就是跟jsb的表现不一致，需要同步修改jsb的代码
