Answer 1

这是一种选择单元格的方法：

UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0]];

现在，如果您想根据文本标签的内容更改单元格：

if ([cell.textLabel.text isEqualToString:@"Red"]) {
    cell.textLabel.textColor = [UIColor redColor];
}

Answer 2

您可以使用cellForRowAtIndexPath方法来获取相应的单元格。请参阅下面的示例以更改列表单元格的文本颜色。

例子：

   UITableViewCell *cell=[self.tblView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0]];
    UILabel *label=cell.textLabel;
    label.textColor=[UIColor redColor];
