iPad拆分視圖中的多個主視圖和詳細視圖，uisplitview

提前致謝。我目前正在開發iPad版本的應用程序，該應用程序在iPhone上有3個選項卡，每個選項卡加載3個不同的RSS提要，然後深入到iPhone上的導航控制器的細節。在iPad上，有意義的是，我在第一個分割視圖中加入了2個供稿，然後爲第3個供稿分別提供了一個主要和詳細信息。iPad拆分視圖中的多個主視圖和詳細視圖，uisplitview

完成此操作的最佳做法是什麼？我現在有建立在第一的DetailView工具欄按鈕，它調用其切換主和細節爲使

- (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]; 


}

當iPad處於橫向而是縱向的barbutton不顯示此工程確定了的appdelegate工具欄，我怎麼能調用 - （void）splitViewController：（UISplitViewController *）svc willHideViewController編程？此外，我的方法的內存管理，我應該釋放，並設置爲無以前的主和細節，因爲我在我的switchViews方法中的那些臨時對象？

另一種方法是將新主人推到舊的位置，只需更換詳細信息即可。這是更好的，聰明的內存，性能等再次感謝
