TableView 中的 DetailView 不起作用（IOS）
我从一个具有带有 4 个按钮的 Tabbar 控制器的程序开始。 在其中一个页面上，viewController 中有一个表视图。当我单击该行时，我想推送 DetailView。但什么也没发生，没有错误什么也没有？？？
有人知道可能出什么问题吗？
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
//Get the selected item
NSString *selectedItem = [listOfItems objectAtIndex:indexPath.row];
//Initialize the detail view controller and display it.
DetailViewController *myController = [[DetailViewController alloc]
initWithNibName:@"DetailViewController"
bundle:[NSBundle mainBundle]];
myController.title = @"Detail View";
myController.selectedItem = selectedItem;
[self.navigationController pushViewController:myController animated:YES];
[myController release];
}
I'm starting with a program that has a Tabbar controller with 4 buttons.
On one of the pages there is a table view in the viewController. And when I click the row I want to push a DetailView. But nothing happens, no errors nothing???
Anybody an idea what can be wrong?
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
//Get the selected item
NSString *selectedItem = [listOfItems objectAtIndex:indexPath.row];
//Initialize the detail view controller and display it.
DetailViewController *myController = [[DetailViewController alloc]
initWithNibName:@"DetailViewController"
bundle:[NSBundle mainBundle]];
myController.title = @"Detail View";
myController.selectedItem = selectedItem;
[self.navigationController pushViewController:myController animated:YES];
[myController release];
}

仅当您的应用程序支持 UINavigation Controller 时，才能导航到另一个视图控制器。如果它在那里，那么其次你的 UITableViewDelegates 不在那里。
为此，您需要
tableView.delegate = self;
或者请详细说明您的问题
Navigation to another View Controller is only can take place when your application supports UINavigation Controller. If It is there then secondly Your UITableViewDelegates are not there.
For this you need to have
tableView.delegate = self;
Or please elaborate your problem more
您确定已设置
UITabelViewDelegate吗？如果没有，请将UITableView的委托设置为同时确保您的头文件实现
UITableViewDelegate协议Are you sure you have set the
UITabelViewDelegate? If not please set the delegate of theUITableViewasAlso make sure your header file implements the
UITableViewDelegateprotocol
