Question

我是iOS开发的新手，需要一些帮助。我搜索了高低，找不到答案。这更像是我不明白发生了什么。我的问题是，我正在尝试在不使用故事板的情况下编写Master-Detail应用程序。这有助于我更好地理解ViewControllers的管理和处理方式。我试图在iPhone上的MasterViewController中的tableView中选择一个项目后呈现DetailViewController。在iPad上它运作良好，因为两个视图是并排的。

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    //Pass data to detailViewController
    if ([_detailDelegate respondsToSelector:@selector(item:selectedAtIndexPath:)]) {

            [_detailDelegate item:[[BNRItemStore sharedStore] findItemAtIndex:indexPath.row] selectedAtIndexPath:indexPath];
    }

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone ) {

        // show DetailViewController


        NSArray *viewControllers = self.splitViewController.viewControllers;

        UINavigationController *detailNavigationViewController = [viewControllers objectAtIndex:1];

        [self showDetailViewController:detailNavigationViewController sender:nil];

    }


}

在故事板中，所选的ViewCell与detailViewController具有show detail segue。如何在不使用故事板的情况下实现同样的目标？

我的AppDelegate代码可以获得更好的图片

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.

self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];

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

self.window.rootViewController = splitViewController;


UINavigationController *masterNavigationController = [[UINavigationController alloc]init];
UINavigationController *detailNavigationController = [[UINavigationController alloc]init];


MasterTableViewController *masterTableViewController = [[MasterTableViewController alloc] init];
DetailViewController *detailViewController = [[DetailViewController alloc] init];

masterTableViewController.detailDelegate = detailViewController;
detailViewController.masterDelegate = masterTableViewController;


masterNavigationController.viewControllers = @[masterTableViewController];
detailNavigationController.viewControllers = @[detailViewController];

[splitViewController setViewControllers:@[masterNavigationController,detailNavigationController]];


[self.window makeKeyAndVisible];

    return YES;
}

感谢。

尝试更改：

    [self showDetailViewController:detailNavigationViewController sender:nil];

为：

    [self.splitViewController showDetailViewController:detailNavigationViewController sender:nil];

UiSplitViewController应用程序没有故事板
