选项卡栏中的uisplitviewcontroller(uitabbarcontroller)?

使用界面生成器,创建拆分视图控制器和选项卡栏控制器,并将它们链接到插座:

@property (nonatomic, retain) IBOutlet UITabBarController *tabBarController;
@property (nonatomic, retain) IBOutlet UISplitViewController *splitViewController;

在你的应用程序代理中 didFinishLaunchingWithOption ,将拆分视图控制器分配给选项卡栏控制器:

splitViewController.tabBarItem = [[[UITabBarItem alloc] initWithTitle:@"Title" image:nil tag:0] autorelease];
NSArray *controllers = [NSArray arrayWithObjects:splitViewController,  /* other controllers go here */ nil];
tabBarController.viewControllers = controllers;
[window addSubview:tabBarController.view];
[window makeKeyAndVisible];

这将创建一个选项卡栏控制器(在本例中只有一个选项卡),该控制器在所有方向上都正确显示。

我已经为uisplitviewcontroller编写了一个子类,它将侦听设备方向的更改并相应地调整自身的方向。有了这个类,我现在可以将拆分视图放在uitabbarcontroller中,并且每个拆分视图在旋转时都将正确工作,即使它不是最前面的选项卡。我已经成功地在 TexLege 它被批准在应用程序商店中使用,但您的里程可能会有所不同。请查看github上的存储库。

你可以随意改变它,我总是对听到关于它的评论(或抱怨)感兴趣。 https://github.com/grgcombs/IntelligentSplitViewController

我做了一个样本申请。发现我们可以通过编程的方式来完成,比如:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    

        NSMutableArray *array = [NSMutableArray array];

        NSMutableArray *tabArray = [NSMutableArray array]; 

        UISplitViewController *splitViewConntroller = [[UISplitViewController alloc] init];

        MainViewController *viewCont = [[MainViewController alloc] initWithNibName:@"MainViewController" bundle:nil];
        [array addObject:viewCont];
        [viewCont release];

        viewCont = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
        [array addObject:viewCont];
        [viewCont release];




        [splitViewConntroller setViewControllers:array];

        [tabArray addObject:splitViewConntroller];

        [splitViewConntroller release];

        array = [NSMutableArray array];

        splitViewConntroller = [[UISplitViewController alloc] init];

        viewCont = [[MainViewController alloc] initWithNibName:@"MainViewController" bundle:nil];
        [array addObject:viewCont];
        [viewCont release];

        viewCont = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
        [array addObject:viewCont];
        [viewCont release];

        [splitViewConntroller setViewControllers:array];

        [tabArray addObject:splitViewConntroller];

        [splitViewConntroller release];

        // Add the tab bar controller's current view as a subview of the window
        [tabBarController setViewControllers:tabArray];

        [window addSubview:tabBarController.view];
        [window makeKeyAndVisible];

        return YES;
    }

希望这有帮助。

要让tabbarcontroller显示为splitviewcontroller的主视图,应该重写tabbarcontroller,使其支持或定向(例如,使用uitabbarcontroller类的类别)

请参阅关于将拆分视图控制器改装为现有选项卡栏界面的文章: http://markivsblog.blogspot.com/2010/04/retrofitting-ipad-uisplitviewcontroller.html

我创建了一个uitabbarcontroller子类,该子类将旋转消息正确地传播到它包含的所有uisplitviewcontroller。这将保持uisplitviewcontroller的正确内部状态。但是,如果splitviewcontroller不可见,则不会调用splitviewcontroller委托方法之一,因此我在详细视图控制器viewwillappear方法中对此进行了说明。我已经在ios5.0-ios6.1中确认了这一点

ostabbarcontroller.m

#import "OSTabBarController.h"

@implementation OSTabBarController

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration{
    [super willRotateToInterfaceOrientation:toInterfaceOrientation duration:duration];
    for(UIViewController *targetController in self.viewControllers){
        if(targetController != self.selectedViewController && [targetController isKindOfClass:[UISplitViewController class]]){
            [targetController willRotateToInterfaceOrientation:toInterfaceOrientation duration:duration];
        }
    }
}

-(void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation{
    [super didRotateFromInterfaceOrientation:fromInterfaceOrientation];
    for(UIViewController *targetController in self.viewControllers){
        if(targetController != self.selectedViewController && [targetController isKindOfClass:[UISplitViewController class]]){
            [targetController didRotateFromInterfaceOrientation:fromInterfaceOrientation];
        }
    }
}

@end

详细视图控制器

@implementation OSDetailViewController

-(void)viewWillAppear:(BOOL)animated{
    //the splitViewController:willHideViewController:withBarButtonItem:forPopoverController: may not have been called
    if(!UIInterfaceOrientationIsPortrait(self.interfaceOrientation)){
        self.navigationItem.leftBarButtonItem = nil;
    }
}

#pragma mark - UISplitViewControllerDelegate Methods

- (void)splitViewController:(UISplitViewController *)splitController willHideViewController:(UIViewController *)viewController withBarButtonItem:(UIBarButtonItem *)barButtonItem forPopoverController:(UIPopoverController *)popoverController
{
    [self.navigationItem setLeftBarButtonItem:barButtonItem animated:YES];

}

- (void)splitViewController:(UISplitViewController *)splitController willShowViewController:(UIViewController *)viewController invalidatingBarButtonItem:(UIBarButtonItem *)barButtonItem
{
    [self.navigationItem setLeftBarButtonItem:nil animated:YES];
}

@end

请记住,OS3.2可以 没有提供适当的支持 作为选项卡栏视图的拆分视图。

你可以让它“工作”,但它会有错误-最大的错误是,在另一个选项卡的视图上所做的方向更改通常不会正确地传播到SplitView选项卡视图,当你返回到它时会使视图变得古怪(左侧视图接管屏幕,或者缺少Barbutton项,eTC)。

我得出的结论是,由于这个问题,我必须创建自己的splitview,以便在tabbarcontroller中使用。

我听说苹果正在进行修复,但是已经几个月了,没有ipad操作系统的更新,也许ipad的os 4会解决这个问题。

您可以使用ib构建tabtab,并将tab修改为splitviewcontroller。

-(void) makeSplitViewController {
NSMutableArray *controllers = [NSMutableArray arrayWithArray:tabBarController.viewControllers];
int index = 0;

for (UIViewController *controller in tabBarController.viewControllers) {
    if ([controller.tabBarItem.title isEqualToString:@"Stock"]) {
        stockDetailController = [[StockDetailController alloc] initWithNibName:@"StockDetailController" bundle:nil];

        stockMasterController = [[StockMasterController alloc] initWithStyle:UITableViewStylePlain]; 
        stockMasterController.navigationItem.title = date;
        stockMasterController.stockDetailController = stockDetailController;

        UINavigationController *nav = [[[UINavigationController alloc] initWithRootViewController:stockMasterController] autorelease];

        splitViewController = [[UISplitViewController alloc] init];
        splitViewController.tabBarItem = controller.tabBarItem;
        splitViewController.viewControllers = [NSArray arrayWithObjects:nav, stockDetailController, nil];
        splitViewController.delegate = stockDetailController;

        [controllers replaceObjectAtIndex:index withObject:splitViewController];
    }

    index++;
}

tabBarController.viewControllers = controllers;

}

我们成功地在带有ios5+的ipad上的uitabviewcontroller中安装了uisplitviewcontroller。

长话短说:它起作用:

• 开箱即用,如果你接受分割也在肖像;
• 有点 工作,如果你想让主视图隐藏在纵向,并且 只要按一下按钮它就会出现。

第二种情况下的诀窍是使用intelligentsplitviewcontroller(参见上面的几篇文章,thanx greg combs)或类似地扩展uisplitvc,并注意splitview控制器的子类的委托始终是一个活动对象。
