Question

当UISPlitViewControler处于弹出模式时，从UISPlitViewControler的主视图中选择一行。是不是应该自动解雇？我该怎么办呢？

通常我会[self.popoverController dismissPopoverAnimated:YES];但popoverController在这种情况下无法识别。

我认为UISplitViewController应该自动执行此操作？

这是我的detailViewCOntroller中的UISplitViewDelegate代码：

- (void)splitViewController:(UISplitViewController *)svc willHideViewController:(UIViewController *)aViewController withBarButtonItem:(UIBarButtonItem *)barButtonItem forPopoverController: (UIPopoverController *)pc
{
    barButtonItem.title = @"Medical Codes";
    NSMutableArray *items = [[self.toolbar items] mutableCopy];
    [items insertObject:barButtonItem atIndex:0];
    [self.toolbar setItems:items animated:YES];
    [items release];
}

// Called when the view is shown again in the split view, invalidating the button and popover controller.
- (void)splitViewController:(UISplitViewController *)svc willShowViewController:(UIViewController *)aViewController invalidatingBarButtonItem:(UIBarButtonItem *)barButtonItem
{
    NSMutableArray *items = [[self.toolbar items] mutableCopy];
    [items removeObjectAtIndex:0];
    [self.toolbar setItems:items animated:YES];
    [items release];
}

在我的app委托中，我有：

@property (nonatomic, retain) IBOutlet UISplitViewController *splitViewController;
@property (nonatomic, retain) IBOutlet DetailViewControlleriPad *rightViewController;
@property (nonatomic, retain) IBOutlet RootViewController * leftViewController;

这些属性与IB联系在一起。 RootViewController会推送到其他tableview，在弹出模式下选择它们时需要将其解除。

修改

- (void)setDetailItem:(id)newDetailItem
{
    if (detailItem != newDetailItem)
    {
        [detailItem release];
        detailItem = [newDetailItem retain];
        [self.myTableView reloadData];
    }
}

我总是必须手动明确地解除弹出窗口。为此，在传递给我的UISplitViewControllerDelegate时获取对popover视图控制器的引用：

- (void)splitViewController:(UISplitViewController*)svc 
     willHideViewController:(UIViewController *)aViewController 
          withBarButtonItem:(UIBarButtonItem*)barButtonItem 
       forPopoverController:(UIPopoverController*)pc
{
    splitViewPopover = [pc retain];
    // Other stuff
}

因为我这样做，所以当它不再有效时我也必须释放它：

- (void)splitViewController:(UISplitViewController*)svc 
     willShowViewController:(UIViewController *)aViewController 
  invalidatingBarButtonItem:(UIBarButtonItem *)button 
{    
    [splitViewPopover release];
    splitViewPopover = nil;
    // Other stuff
}

然后，当在我的主视图控制器中选择了一个项目时，我更新了我的细节控制器并解除了弹出窗口：

[splitViewPopover dismissPopoverAnimated:NO];

选择行时忽略弹出窗口？
