如何在 uisplitviewcontroller 中关闭 NavigationController 后重新加载 tableView？

我使用 UISplitviewController 作为模板。

编辑按钮的操作：

newExViewController *editWindow =[[newExViewController alloc]initWithNibName:@"newExViewController" bundle:nil];
UINavigationController *navBar=[[UINavigationController alloc]initWithRootViewController:editWindow];
navBar.modalPresentationStyle = UIModalPresentationFormSheet;
navBar.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;

[self presentModalViewController:navBar animated:YES];
[navBar release];

[editWindow release];

navBar 有一个用于 saveButton 的 UIBarButton。现在，当您按下 SaveButton 时会调用此方法，这

[self dismissModalViewControllerAnimated:YES];

就是问题所在：知道如何在 modalView 关闭时重新加载主 NavigationConteroller 和DetailViewController 的数据吗？我不知道谢谢

I'm using a UISplitviewController as a template.

action for edit button:

newExViewController *editWindow =[[newExViewController alloc]initWithNibName:@"newExViewController" bundle:nil];
UINavigationController *navBar=[[UINavigationController alloc]initWithRootViewController:editWindow];
navBar.modalPresentationStyle = UIModalPresentationFormSheet;
navBar.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;

[self presentModalViewController:navBar animated:YES];
[navBar release];

[editWindow release];

navBar has a UIBarButton for saveButton. This is called when you press SaveButton

[self dismissModalViewControllerAnimated:YES];

now is the problem:
any idea how to reload the data for both the main NavigationConteroller and the detailViewController when the modalView is dismissed??
I have no clue
thnx

您应该查看 NSNotificationCenter。在您的 UITableView 视图中，创建通知侦听器。然后在关闭的视图中调用该通知。

更具体地说，通知将调用一个应包含 reloadData 的方法。

示例

以下内容应与您要重新加载的 UITableView 一起使用：

这可以与您的 [selfmissModalViewControllerAnimated:YES]; 一起使用，

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(someMethodToReloadTable) name:@"reloadTable" object:nil];

这是您调用通知中心来重新加载表格的方式：

[[NSNotificationCenter defaultCenter] postNotificationName:@"reloadTable" object:self];

示例通知方法：

- (void)someMethodToReloadTable:(NSNotification *)notification 
{
    [myTableView reloadData];  
}

并且不要忘记删除通知观察者：

-(void)viewDidUnload 
{
    [[NSNotificationCenter defaultCenter] removeObserver:self name:@"reloadTable" object:nil];
}

You should look into NSNotificationCenter. In your view with the UITableView, create the notification listener. Then in the view that dismisses, call that notification.

To be more specific, the Notification will call a method that should contain reloadData.

Example

The following should go with the UITableView you want to reload:

This could go along with your [self dismissModalViewControllerAnimated:YES];

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(someMethodToReloadTable) name:@"reloadTable" object:nil];

This is how you will call the notification center to reload the table:

[[NSNotificationCenter defaultCenter] postNotificationName:@"reloadTable" object:self];

Example of the notification method:

- (void)someMethodToReloadTable:(NSNotification *)notification 
{
    [myTableView reloadData];  
}

And don't forget to remove the notificaiton observer:

-(void)viewDidUnload 
{
    [[NSNotificationCenter defaultCenter] removeObserver:self name:@"reloadTable" object:nil];
}

在包含要重新加载的视图的控制器中，您应该拒绝以下方法，该方法将在 modalView 被关闭时（或首次加载控制器的主视图时）被调用：

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    // here you can reload needful views, for example, tableView:
    [tableView reloadData];
}

In controllers, that contains view you want to reload, you should decline following method which will be called when the modalView will be dismissed (or when controller's main view will be first time loaded):

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    // here you can reload needful views, for example, tableView:
    [tableView reloadData];
}
