Split View是iPad专用的容器,用于并排管理两个视图控制器的视图控制器。
步骤1 - 创建一个新项目,然后选择 Master Detail Application (而不是基于View的应用程序),然后单击"Next",输入项目名称并选择create。
步骤2 - 默认情况下,将创建一个简单的拆分视图控制器,该控件在master中具有表视图。
步骤3 - 这些文件创建的内容与基于View的应用程序略有不同。在这里,无涯教程为无涯教程创建了以下文件。
步骤4 - AppDelegate.h 文件如下-
#import <UIKit/UIKit.h> @interface AppDelegate : UIResponder <UIApplicationDelegate> @property (strong, nonatomic) UIWindow *window; @property (strong, nonatomic) UISplitViewController *splitViewController; @end
步骤5 - AppDelegate.m 中的 didFinishLaunchingWithOptions 方法如下-
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen]bounds]]; //应用程序启动后自定义的覆盖点。 MasterViewController *masterViewController = [[MasterViewController alloc] initWithNibName:@"MasterViewController" bundle:nil]; UINavigationController *masterNavigationController = [[UINavigationController alloc] initWithRootViewController: masterViewController]; DetailViewController *detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil]; UINavigationController *detailNavigationController = [[UINavigationController alloc] initWithRootViewController: detailViewController]; masterViewController.detailViewController = detailViewController; self.splitViewController = [[UISplitViewController alloc] init]; self.splitViewController.delegate = detailViewController; self.splitViewController.viewControllers = @[masterNavigationController, detailNavigationController]; self.window.rootViewController = self.splitViewController; [self.window makeKeyAndVisible]; return YES;
步骤6 - MasterViewController.h如下-
#import <UIKit/UIKit.h> @class DetailViewController; @interface MasterViewController : UITableViewController @property (strong, nonatomic) DetailViewController *detailViewController; @end
步骤7 - MasterViewController.m如下-

步骤8 - DetailViewController.h如下-
#import <UIKit/UIKit.h> @interface DetailViewController : UIViewController <UISplitViewControllerDelegate> @property (strong, nonatomic) id detailItem; @property (weak, nonatomic) IBOutlet UILabel *detail描述Label; @end
步骤9 - DetailViewController.m如下-
#import "DetailViewController.h" @interface DetailViewController () @property (strong, nonatomic) UIPopoverController *masterPopoverController; - (void)configureView; @end @implementation DetailViewController #pragma mark - Managing the detail item - (void)setDetailItem:(id)newDetailItem { if (_detailItem != newDetailItem) { _detailItem = newDetailItem; //Update the view. [self configureView]; } if (self.masterPopoverController != nil) { [self.masterPopoverController dismissPopoverAnimated:YES]; } } - (void)configureView { //更新详细信息项的用户界面。 if (self.detailItem) { self.detailRemarkLabel.text = [self.detailItem description]; } } - (void)viewDidLoad { [super viewDidLoad]; [self configureView]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; //处置任何可以重新创建的资源。 } - (id)initWithNibName:(NSString *)nibNameOrNil bundle: (NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { self.title = NSLocalizedString(@"Detail", @"Detail"); } return self; } #pragma mark - Split view - (void)splitViewController:(UISplitViewController *)splitController willHideViewController:(UIViewController *)viewController withBarButtonItem: (UIBarButtonItem *)barButtonItem forPopoverController: (UIPopoverController *)popoverController { barButtonItem.title = NSLocalizedString(@"Master", @"Master"); [self.navigationItem setLeftBarButtonItem:barButtonItem animated:YES]; self.masterPopoverController = popoverController; } - (void)splitViewController:(UISplitViewController *)splitController willShowViewController:(UIViewController *)viewController invalidatingBarButtonItem:(UIBarButtonItem *)barButtonItem { //当视图在拆分视图中再次显示时调用, //使按钮和弹出框控制器无效。 [self.navigationItem setLeftBarButtonItem:nil animated:YES]; self.masterPopoverController = nil; } @end
