How to unselect a uitableview cell when the user returns to the view controller
提问by hanumanDev
I have a uitableview cell highlighted when a user selects it and then is pushed to a detail view. I would like the cell to be unhighlighted when they return to the table view view controller.
当用户选择它然后被推送到详细信息视图时，我有一个 uitableview 单元格突出显示。我希望单元格在返回到表视图视图控制器时不突出显示。
how would I go about accomplishing this?
我将如何实现这一目标？
I'm guessing [cell.textLabel setHighlighted:NO];in viewWillAppear, but cell is undeclared if I put it there.
我猜 [cell.textLabel setHighlighted:NO];在 viewWillAppear 中，但如果我把它放在那里，单元格是未声明的。
thanks for any help
谢谢你的帮助

If you using UITableViewControllersubclass then just set property
如果您使用UITableViewController子类，则只需设置属性
self.clearsSelectionOnViewWillAppear = YES;
else on viewDidAppear just call
其他 viewDidAppear 只需调用
NSIndexPath *indexPath = self.tableView.indexPathForSelectedRow;
if (indexPath) {
[self.tableView deselectRowAtIndexPath:indexPath animated:animated];
}
// MARK: - Swift 3
if let indexPath = tableView.indexPathForSelectedRow {
tableView.deselectRow(at: indexPath, animated: true)
}

override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
if let selectionIndexPath = self.tableView.indexPathForSelectedRow {
self.tableView.deselectRow(at: selectionIndexPath, animated: animated)
}
}

try
尝试
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// Deselect the row which was tapped
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}

I decided to make this an answer instead of a comment.
我决定将此作为答案而不是评论。
If you are using storyboard: Click on your UITableViewController -> Check the "Selection: Clear on Appearance" box
如果您使用的是故事板：单击您的 UITableViewController -> 选中“选择：清除外观”框

func clearOnAppearance() {
for indexPath in tableView.indexPathsForSelectedRows ?? [] {
tableView.deselectRow(at: indexPath, animated: true)
}
}

Or some inelegant way =)
或者一些不雅的方式 =)
NSArray *arrayWithPaths = [tableView indexPathsForVisibleRows];
for (NSIndexPath *path in arrayWithPaths)
{
[tableview deselectRowAtIndexPath:path animated:NO];
}
