UILabel文本重叠更新？ [英] UILabel text overlapping on update?

问题描述

在我的应用程序中，我将文本标签的值从初始值0更改为触摸事件增加。有时，但不是所有的时间，新的值将覆盖在0，这是不冷的。

In my app I change the value of a text label from an initial value of 0 and increment it on a touch event. Sometimes, but not all the time, the new value will be overlayed over the 0, which is not cool..

这是相关的代码：

UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
UILabel *label = (UILabel *)[cell viewWithTag:1000];
label.text = qtyString;

我已经尝试从视图中删除标签，然后添加另一个与新的值，没有影响到所有的问题。当我将单元格（标签是表格单元格的一部分）滚出屏幕并返回时，标签会正确显示。哦，我也尝试过

I've tried removing the label from the view, then adding another with the new value, but it didn't affect the problem at all. When I scroll the cell (the labels are part of a table cell) out of the screen and back in, the labels display correctly. Oh, and I've also tried doing

[tableView reloadData];

它效果更好，但如果我选择一个单元格，然后滚动，

And it works better, but if I select a cell and then scroll while it is higlighted it poops out on that cell.
