uitableview + navigation controller set title from selected element
提问by obithemaster
I have a UINnavigationControllerthat handles the navigation in a UITableView.
我有一个UINnavigationController处理UITableView.
When I select a row from the table I need to display in the UINavigationControllertitle the selected item from the previous menu.
当我从表中选择一行时，我需要在UINavigationController标题中显示上一个菜单中的所选项目。
The label of the cell is read from an external xmlthat fills the rows of the UITableView.
单元格的标签是从xml填充UITableView.
How can I display my selection on the title of the UINavigationBar?

Would this work for you?
这对你有用吗？
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;
{
DetailTableViewController *detailController = [[DetailTableViewController alloc] initWithStyle:UITableViewStyleGrouped];
// Set the detail controller title to whatever you want here...
detailController.title = @"Your title";
// Or set it to the title of this row
UITableViewCell *cell = [[self tableView] cellForRowAtIndexPath:indexPath];
detailController.title = cell.textLabel.text;
[[self navigationController] pushViewController:detailController animated:YES];
}

Normaly the UINavigationControlleralways picks out the titleof the UIViewControllerwhich has been actually loaded. Thats why you have to define it inside viewDidLoad:
Normaly的UINavigationController总是挑选出title了的UIViewController已实际加载。这就是为什么你必须在里面定义它viewDidLoad：
self.title = @"Title";
The method displayed above seems to be more dynamic...but this also works.
上面显示的方法似乎更动态……但这也有效。
