当我点击一个uitableview单元格时，该单元格的文本变得更大胆。我该怎么办？

return cell;
这是我上面的cellForRowAtIndexPath代码。
当我点击一个单元格时，单元格的文本变得更清晰......
我该怎么办？
如何制作它以便在选择单元格时不会变得更大胆或更锐利？感谢。

每次重新绘制细胞时，都会添加UILabel（和图像视图）。这不是你想要的。 Yi想要在现有标签上设置文本 - 但是您将标签堆叠在一起。
您应该创建一个自定义UITableViewCell子类。
正如您所描述的那样，触摸增加了字体大小，我假设你做[tableview reloadData];在tableView:didSelectRowAtIndexPath:。

尝试类似这样的事情。
- (void)tableView:(UITableView *)tableview didSelectRowAtIndexPath:(NSIndexPath *)index
{
UITableViewCell *cell = [tableview cellForRowAtIndexPath:index];
cell.textLabel.font = [UIFont boldSystemFontOfSize:14.0];
}
答案 2 :(得分：0)
您还可以对UITableViewCell进行子类化并覆盖方法
- (void) setSelected: (BOOL) selected
animated: (BOOL) animated
{
[super setSelected: selected
animated: animated];
if (selected)
{
cell.textLabel.font = [UIFont boldSystemFontOfSize: 14.0];
}
else
{
cell.textLabel.font = [UIFont systemFontOfSize: 14.0];
}
}
