Ios6 在UISplitViewController（主详细信息模板）中以编程方式显示和隐藏popover（MasterViewController）

我想添加一个显示/隐藏popover的按钮，类似于DropBox应用程序的按钮。 无论是风景画还是肖像画

我已经尝试了很多解决方案，但在这个阶段，我甚至不想因为我的尝试而弄脏水。如果你已经这样做了，或者知道怎么做，请把我送到正确的方向

谢谢

看起来很简单

将某个对象设置为splitViewController的代理。在我的例子中，我以编程方式创建了所有的ViewController，即appdelegate

UISplitViewController* splitViewController = [[UISplitViewController alloc] init]; [splitViewController setViewControllers:@[navigationViewController1, navigationViewController2]]; splitViewController.delegate = self; 实现委托方法以纵向隐藏主控形状：

- (BOOL)splitViewController:(UISplitViewController *)svc shouldHideViewController:(UIViewController *)vc inOrientation:(UIInterfaceOrientation)orientation { return UIInterfaceOrientationIsPortrait(orientation); } - (void)splitViewController:(UISplitViewController *)svc willShowViewController:(UIViewController *)aViewController invalidatingBarButtonItem:(UIBarButtonItem *)barButtonItem { UINavigationController* slaveNavigationViewController = svc.viewControllers[1]; UIViewController* slaveViewController = slaveNavigationViewController.viewControllers[0]; [barButtonItem setTitle:@"Drops"]; slaveViewController.navigationItem.leftBarButtonItem = nil; } 实际上，添加巴布通主义：

-(void)splitViewController:(UISplitViewController *)svc willHideViewController:(UIViewController *)aViewController withBarButtonItem:(UIBarButtonItem *)barButtonItem forPopoverController:(UIPopoverController *)pc { UINavigationController* slaveNavigationViewController = svc.viewControllers[1]; UIViewController* slaveViewController = slaveNavigationViewController.viewControllers[0]; [barButtonItem setTitle:@"Your master title"]; slaveViewController.navigationItem.leftBarButtonItem = barButtonItem; } 在这个方法中，您将获得BarButtonim，您可以自定义它并将其添加到slaveViewController中

最后，在横向方向上移除按钮：

- (BOOL)splitViewController:(UISplitViewController *)svc shouldHideViewController:(UIViewController *)vc inOrientation:(UIInterfaceOrientation)orientation { return UIInterfaceOrientationIsPortrait(orientation); } - (void)splitViewController:(UISplitViewController *)svc willShowViewController:(UIViewController *)aViewController invalidatingBarButtonItem:(UIBarButtonItem *)barButtonItem { UINavigationController* slaveNavigationViewController = svc.viewControllers[1]; UIViewController* slaveViewController = slaveNavigationViewController.viewControllers[0]; [barButtonItem setTitle:@"Drops"]; slaveViewController.navigationItem.leftBarButtonItem = nil; }

就是这样。

有一种更简单、无文档记录的方法。对于现有的UIButton：

[button addTarget: theSplitViewController action: @selector(toggleMasterVisible:) forControlEvents:UIControlEventTouchUpInside];

---

此目标/操作与在willHideViewController函数中发送的barButtonItem的目标/操作相同。

如果我想在横向中隐藏主视图，该怎么办？要在纵向和横向中隐藏主视图，只需在-BOOLsplitViewController:UISplitViewController*svc shoulldhideViewController:UIViewController*vc中返回yesinOrientation:UIInterfaceOrientationorientation{return YES；}谢谢Norman G，但我想要的应该更像DropBox应用程序：在横向模式下，当弹出窗口显示时，它不应该覆盖细节，而应该调整细节窗口的大小以适应剩余空间。你知道怎么做吗？我的问题是BOOLsplitViewController:UIPlitviewcontroller*svc应该在视图控制器：UIViewController*vc inOrientation:UIInterfaceOrientationOrientationOrientation只有在通过物理旋转改变设备的方向时才会触发。如果我想在横向中隐藏主视图呢在纵向和横向中隐藏主视图只需在BOOLsplitViewController:uiplitviewcontroller*svc应在hideviewcontroller:UIViewController*vc inooritation:uiinterface-orientation:uiinterface-orientation{return-yes；}谢谢Norman G，但我想要的应该更像DropBox应用程序：在横向模式下，显示弹出窗口时，它不应覆盖详图，而应调整详图窗口的大小以适应剩余空间。你知道怎么做吗？我的问题是BOOLsplitViewController:UISplitViewController*svc应该是ideviewcontroller:UIViewController*vc inooritation:uiinterface-oritationoritationoritationoritation只有在通过物理旋转改变设备的方向时才会启动。谢谢，我很快就会试一试！谢谢，我很快就会试一试的！
