重新启用用户交互后更改UITableViewCell的颜色 [英] change color of UITableViewCell after reenabled userinteraction

问题描述

在我的应用中，我有一些菜单项，这些菜单项无法进行用户交互.

in my app, i've some menupoints, that are disabled for userinteraction.

   cell.userInteractionEnabled = FALSE;

登录后，我想重新启用其中一些单元格.

after the login, i want to reenable some of these cells.

此代码段运行一半:

   NSIndexPath *editUsersPath = [NSIndexPath indexPathForRow:0 inSection:1];
        [self.tableView cellForRowAtIndexPath:importPath].userInteractionEnabled = YES;
        [self.tableView cellForRowAtIndexPath:importPath].accessoryType =         UITableViewCellAccessoryDisclosureIndicator;
        [self.tableView cellForRowAtIndexPath:importPath].textLabel.textColor = [UIColor blackColor];

，但是最后一行代码不起作用-文本像以前一样是灰色的.

but the last line of code is not working - the text is gray as before.

推荐答案

更改后您是否正在重画单元格?也许您可以尝试调用setNeedsLayout重绘单元格.

Are you doing any cell redrawing after the changes? Perhaps you can try calling setNeedsLayout to redraw the cell.
