iPad拆分视图中的多个主视图和详细视图，uisplitview

提前致谢。我目前正在开发iPad版本的应用程序，该应用程序在iPhone上有3个选项卡，每个选项卡加载3个不同的RSS提要，然后深入到iPhone上的导航控制器的细节。在iPad上，有意义的是，我在第一个分割视图中加入了2个供稿，然后为第3个供稿分别提供了一个主要和详细信息。iPad拆分视图中的多个主视图和详细视图，uisplitview

完成此操作的最佳做法是什么？我现在有建立在第一的DetailView工具栏按钮，它调用其切换主和细节为使

- (void)switchViews { 

    VideoSelectorViewController *masterViewController = nil; 
    VideoDetailiPadViewController *detailViewController = nil; 
    UIViewController *tempDetail = [self.splitViewController.viewControllers objectAtIndex:1]; 
    UIViewController *tempMaster = [self.splitViewController.viewControllers objectAtIndex:0]; 
    [tempDetail.view removeFromSuperview]; 
    [tempMaster.view removeFromSuperview]; 
    [tempDetail release]; 
    [tempMaster release]; 
    tempDetail = nil; 
    tempMaster = nil; 

    // if (row == 1) { 
     VideoSelectorViewController *newMasterViewController = [[VideoSelectorViewController alloc] initWithNibName:@"VideoSelectorViewController" bundle:nil]; 
     masterViewController = newMasterViewController; 

     VideoDetailiPadViewController *newDetailViewController = [[VideoDetailiPadViewController alloc] initWithNibName:@"VideoDetailiPadViewController" bundle:nil]; 
     detailViewController = newDetailViewController; 

    // } 

    // Update the split view controller's view controllers array. 
    NSArray *viewControllers = [[NSArray alloc] initWithObjects:masterViewController, detailViewController, nil]; 
    self.splitViewController.viewControllers = viewControllers; 
    [viewControllers release]; 

/* // Dismiss the popover if it's present. 
    if (popoverController != nil) { 
     [popoverController dismissPopoverAnimated:YES]; 
    }*/ 

    // Configure the new view controller's popover button (after the view has been displayed and its toolbar/navigation bar has been created). 
    // if (detailViewController.popover != nil) { 
     [detailViewController showRootPopoverButtonItem:detailViewController.rootPopoverButtonItem]; 
    //} 

    [masterViewController release]; 
    [detailViewController release]; 


}

当iPad处于横向而是纵向的barbutton不显示此工程确定了的appdelegate工具栏，我怎么能调用 - （void）splitViewController：（UISplitViewController *）svc willHideViewController编程？此外，我的方法的内存管理，我应该释放，并设置为无以前的主和细节，因为我在我的switchViews方法中的那些临时对象？

另一种方法是将新主人推到旧的位置，只需更换详细信息即可。这是更好的，聪明的内存，性能等再次感谢
