Ios [\uu\u NSOrderedSetM objectAtIndex:]：索引10超出范围[0..9[

我将包含要在表视图中使用的所有JSON对象的主数据结构从NSMutableArray更改为NSMutableOrderedSet。现在，我的应用程序正确地从API加载了前十个对象，但当我想向下滚动时，它崩溃了。有什么建议吗

编辑2：编辑对象的屏幕截图。向下滚动视图时计数

---

它在哪一行崩溃？（您可以使用异常断点来确定它当前是否未被报告。）它在我的“cellForIndexPath”函数中崩溃，在我使用函数“objectAtIndex”的第一行。我刚刚添加了cellForIndexPath代码。您从

numberOfRowsInSection

返回什么？（应该是editorialObjects的计数）我不小心将其更改为nodeIDArray.count，尽管我显然知道正确的是editorialObjects.count（这是我之前设置的，我只是想测试不同的值，看看会发生什么）。错误现在消失了。如果您能帮我解决另一个问题，那将是非常棒的。当我激活“scrollViewDidScroll”时方法通过向下滚动视图，editorialObjects集合中不会添加任何内容。我打印了editorialObjects.count值，但它没有超过10，即使在我使用NSMutableArray时，它确实超过了10。我添加了一个屏幕截图，以便您可以查看发生了什么。当我删除时，表视图也完全停止添加表单元格滚下来。
