iPhone-是否可以重写UITableViewCell setSelected：animated [英] iPhone - Is it ok to override UITableViewCell setSelected:animated

问题描述

我正在绘制自定义UITableViewCells。我的单元格是不透明的，并已完全绘制在单元格的drawRect中以帮助提高性能。我想自己处理选定单元格的外观。如果我不这样做，那么所添加的selectedBackgroundView将覆盖单元格的内容。覆盖我的单元格的setSelected：animated方法是常见还是可接受的，因此可以正确完成此操作。我猜想如果这样做的话，我就不会调用super的setSelected方法，因为我将处理单元格如何显示其已选择状态。我还必须设置该单元格的选定属性。

I am drawing custom UITableViewCells. My cells are opaque and are completely drawn in the drawRect of the cell to help with performance. I want to handle the look of a selected cell myself. If I don't, then the contents of my cell is covered up by the selectedBackgroundView that is added. Is it common or acceptable to override the setSelected:animated method of my cell so this is done properly. I guess if I did that, then I would not call the super's setSelected method since I would be handling how the cell will show that its selected. I would also have to set the selected property of the cell.

任何帮助都会很棒。谢谢。

Any help would be great. Thanks.

推荐答案

您可以覆盖-[UITableViewCell setSelected：animated：] ，但您应始终在实现中调用super的实现。不这样做可能会对其他与选择相关的行为产生意想不到的影响。

You can override -[UITableViewCell setSelected:animated:], but you should always call the super's implementation in your implementation. Not doing so could have have unanticipated effects on other selection-related behaviors.

如果您不希望超类由于选择而进行任何样式更改，只需将单元格的 selectionStyle 属性设置为 UITableViewCellSelectionStyleNone 。

If you don't want the superclass to make any styling changes as a result of the selection, just set the cell's selectionStyle property to UITableViewCellSelectionStyleNone.
