ios - 缺少 "master"按钮和滑动手势不起作用主/详细 ios

我创建了 Master detail 应用程序，其中包含多个通过替换 segue 连接到 Split View的详细 View Controller 。在横向上一切正常，但在纵向上我缺少打开主表格 View 和在屏幕左侧滑动的按钮不起作用，也没有打开应用程序的主侧。

编辑:

在我的 DetailViewController 中，我有两种方法，与 xcode 为 master-detail 应用程序提供的模板中相同:

#pragma mark - Split view

- (void)splitViewControllerUISplitViewController *)splitController willHideViewControllerUIViewController *)viewController withBarButtonItemUIBarButtonItem *)barButtonItem forPopoverControllerUIPopoverController *)popoverController
{
    barButtonItem.title = NSLocalizedString(@"MasterButton", @"Master");
    [self.navigationItem setLeftBarButtonItem:barButtonItem animated:YES];
    self.masterPopoverController = popoverController;
}

- (void)splitViewControllerUISplitViewController *)splitController willShowViewControllerUIViewController *)viewController invalidatingBarButtonItemUIBarButtonItem *)barButtonItem
{
    // Called when the view is shown again in the split view, invalidating the button and    popover controller.
    [self.navigationItem setLeftBarButtonItem:nil animated:YES];
    self.masterPopoverController = nil;
}

编辑 2: 在更改我的 detailViewController 时，我也更改了委托(delegate)。

- (void)prepareForSegueUIStoryboardSegue *)segue senderid)sender
{
    UIViewController *destinationViewController = [segue destinationViewController];
    if ([destinationViewController conformsToProtocolprotocol(UISplitViewControllerDelegate)]) {
        self.splitViewController.delegate = (id)destinationViewController;
    }
    else {
        self.splitViewController.delegate = nil;
    }
}

编辑 3: 我终于通过在我创建的每个 DetailViewController 中添加这行代码来解决我的问题:

self.splitViewController.delegate = self;

Best Answer-推荐答案

你需要放置 barButtonItem from

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

在细节 View Controller 的导航栏。
