}

我使用上面的代码实现了表视图。当我选择行号时。 26伏或更高扩展选择，但下次点击不收缩。＆amp;给我滚动错误

NSInternalInconsistencyException'，原因：'与UITableView一起使用的索引路径无效。传递给表视图的索引路径必须包含指定节和行的两个索引。如果可能，请在UITableView.h中使用NSIndexPath上的类别。'

代码平滑地工作25行。哪里出错了？

Answer 1

我最终得到了它。:) selectedIndexpath给了垃圾。我用self.selectedIndexpath替换它。我没有得到它为什么这样做的记录没有。 25开始。但这对我有用

Answer 2

像这样使用

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:sender.tag-1 inSection:0];

CGRect rectOfCellInTableView = [objTableView rectForRowAtIndexPath:indexPath];

CGRect rectOfCellInSuperview = [objTableView convertRect:rectOfCellInTableView toView:[objTableView superview]];

选择超过特定数字的行时，与UITableView一起使用的索引路径无效
