UISplitviewController Master中的iOS8 TabbarController-Java 学习之路

我试图通过在MasterView的UINavigationController前面添加一个UITabbarController来扩展默认的Apple MasterDetail模板，所以有一个这样的结构：

UISplitViewController（Master）> UITabbarController> UINavigationController> UITableViewController

但是如果我运行App，在更改应用程序（didFinishLaunchingWithOptions）以使用正确的ViewController之后，并尝试执行ShowDetails Segue，则会在iPhone上以模态方式呈现DetailsView . 另一方面，iPad版本正在按预期工作 . 我忘记做什么了？或者我该如何解决？

只是为了更新上面的答案 . 由于您无法再推送导航控制器，因此您必须推送其顶视图控制器 .

func splitViewController(splitViewController: UISplitViewController, showDetailViewController vc: UIViewController, sender: AnyObject?) -> Bool {
        if splitViewController.collapsed {
            let tabBarController = splitViewController.viewControllers.first as! UITabBarController
            let selectedNavigationViewController = tabBarController.selectedViewController as! UINavigationController

            // Push view controller
            var viewControllerToPush = vc
            if let navController = vc as? UINavigationController {
                viewControllerToPush = navController.topViewController
            }
            selectedNavigationViewController.pushViewController(viewControllerToPush, animated: true)

            return true
        }

        return false
    }

我想出了如何将细节放到master的UINavigationController上，而不是通过UITabBarController以模态方式呈现它 .

使用 UISplitViewControllerDelegate 方法

- splitViewController:showDetailViewController:sender:

如果UISplitViewController折叠，请获取主控导航控制器并将详细视图推送到此导航控制器：

- (BOOL)splitViewController:(UISplitViewController *)splitViewController
   showDetailViewController:(UIViewController *)vc
                     sender:(id)sender {
    NSLog(@"UISplitViewController collapsed: %d", splitViewController.collapsed);

    // TODO: add introspection
    if (splitViewController.collapsed) {
        UITabBarController *master = (UITabBarController *) splitViewController.viewControllers[0];
        UINavigationController *masterNavigationController = (UINavigationController *)master.selectedViewController;

        // push detail view on the navigation controller
        [masterNavigationController pushViewController:vc animated:YES];

        return YES;
    }

    return NO;
}

这是我的解决方案 . 放置在MasterViewController.m中并记住在IB中为您的详细信息视图提供故事板ID . 在我的情况下'细节' .

-(BOOL)shouldPerformSegueWithIdentifier:(NSString *)identifier sender:(id)sender {
    if ([identifier isEqualToString:@"showDetail"] && self.splitViewController.collapsed) {
        DetailViewController *myController = (DetailViewController *)[self.storyboard instantiateViewControllerWithIdentifier:@"detail"];
        NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
        NSManagedObject *object = [[self fetchedResultsController] objectAtIndexPath:indexPath];
        [myController setDetailItem:object];
        [self.navigationController showViewController:myController sender:self];
         return NO;
    }
    return YES;
}

没有代码，还有另一种方法可以做到这一点 .

在TabBarController中嵌入UINavigationController后，将TabBarController嵌入到另一个UINavigationController中 . 所以你将拥有：SplitViewController - > Master - > NavCon - > TabBar - > NavCon - > TableViewController .

像这样做更容易，但有一个我没有找到如何解决的错误 . 显示的导航栏将是TabBarController的导航栏，而不是TableViewController . 任何想法如何解决？

像这样的子类TabBarController：

- (void)showViewController:(UIViewController *)vc sender:(id)sender
{
    if ([self.selectedViewController isKindOfClass:UINavigationController.class])
        [self.selectedViewController showViewController:vc sender:sender];
    else
        [super showViewController:vc sender:sender];
}

- (UIViewController*)separateSecondaryViewControllerForSplitViewController:(UISplitViewController *)splitViewController
{
    return [self.selectedViewController separateSecondaryViewControllerForSplitViewController:splitViewController];
}

- (void)collapseSecondaryViewController:(UIViewController *)secondaryViewController forSplitViewController:(UISplitViewController *)splitViewController
{
    [self.selectedViewController.navigationController collapseSecondaryViewController:secondaryViewController forSplitViewController:splitViewController];
}

有关完整说明，请参见this question .

这是一个基于测试splitViewController的大小类的替代方法：

使用自定义UISplitViewController（子类）
重写showDetailViewController操作
使用traitCollection确定UISplitViewController的类
如果水平类是Compact，请让navigationController调用showViewController

这是自定义UISplitViewController的代码：

import UIKit

class CustomSplitViewController: UISplitViewController {

    override func showDetailViewController(vc: UIViewController!, sender: AnyObject!) {

        if (self.traitCollection.horizontalSizeClass == UIUserInterfaceSizeClass.Compact) {
            if let tabBarController = self.viewControllers[0] as? UITabBarController {
                if let navigationController = tabBarController.selectedViewController as? UINavigationController {
                    navigationController.showViewController(vc, sender: sender)
                    return
                }
            }
        }

        super.showDetailViewController(vc, sender: sender)
    }
}

Do not forget to the set the custom class in the storyboard.

在iPhone 6，iPhone 6和iPad Air的模拟器中测试并按预期工作 .
