UISplitViewController：如何通过按钮事件而不是通过滑动手势在详细视图中显示主视图

Question

滑动手势很酷，可以纵向显示主视图。但我想知道如何通过按钮事件而不是通过滑动手势来呈现表格。我不想呈现popover，我喜欢幻灯片动画。任何意见将不胜感激。

为了将来参考，通过设置拆分视图控制器委托并实现这两种方法，您应该准备好了。

- (void)splitViewController:(UISplitViewController *)svc willShowViewController:(UIViewController *)aViewController invalidatingBarButtonItem:(UIBarButtonItem *)button
    {
        //remove button from navigation bar in detail navigation controller
        ((UINavigationController*)[svc.viewControllers objectAtIndex:1]).topViewController.navigationItem.leftBarButtonItem = nil;
    }

- (void)splitViewController: (UISplitViewController*)svc willHideViewController:(UIViewController *)aViewController withBarButtonItem:(UIBarButtonItem*)barButtonItem forPopoverController: (UIPopoverController*)pc{

        //add button to navigation bar in detail navigation controller
        barButtonItem.title = @"Navigation";
        ((UINavigationController*)[svc.viewControllers objectAtIndex:1]).topViewController.navigationItem.leftBarButtonItem = barButtonItem;

    }

barButtonItem的实例为您处理所有切换过程。
