如果重新选择了选定的单元格，如何查看 [英] How to chack if selected cell got reselected

问题描述

我有一个自定义的UITableViewCell，我扩展了选择范围。如果重新选择了所选的单元格，我想要做的是让单元格高度恢复正常（44）。这是我的代码：

I have a custom UITableViewCell, and I it expands on selection. What I want to do is make the cells height go back to normal (44), if the cell that was selected was reselected. Here is my code:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    if ([indexPath isEqual:self.selectedCell] && ![[tableView indexPathForSelectedRow] isEqual:indexPath]) {
        return 100;
    }
    return 44;
}

代码工作正常，但它似乎忽略了if语句中的第二个术语。显然我做错了。有没有办法解决它？

The code works fine, but it seems to be ignoring the 2nd term in the if statement. Apparently I'm doing it wrong. Is there a way to fix it?

推荐答案

处理这样的东西。

Handle such stuff in the handler.

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath;
- (void)collectionView:(UICollectionView *)collectionView didDeselectItemAtIndexPath:(NSIndexPath *)indexPath;

heightForRowAtIndexPath仅在加载过程中调用一次。

The heightForRowAtIndexPath is only called once in the load process.
