发生的事情是我有一个分段视图控件，当我切换段时，我将使用不同的数据重新加载我的tableview。在这种情况下，一个部分将重新加载30+，另一个部分重新加载11个。 在滚动和来回切换时发现了这个问题，它达到了寻找索引30的程度，但是我的数组中只有11个对象。如果我不是很快这样做，那很好。 在重新加载表之前滚动到顶部没有帮助。
查看我的日志并注意模式，最后一个日志显示在cellforRow之前没有调用numberOfrows
我试过调用在主线程上重新加载表的方法，等到完成。
我还尝试在重新加载之前滚动到顶部。
问题似乎是当我快速滚动并切换到新细分时。
日志按此顺序排列： 1.在排列数据之前，这是我点击该段的时间 2.在我安排数据并交换数组之后 3.在numberOfRows中 4.在cellforRows中。
最后一个序列跳过了第三步。
