在ios中显示iPad的侧边栏，就像facebook在景观设计中一样

Question

我有一个iPad应用程序，我想在其中实现一个边栏功能，就像我们在facebook应用程序一样。

为此，我使用了这个演示。

有了这个，我成功地实现了侧栏功能，并且它运行得很好，但是我的第一个视图并没有很好地展示给我。

下面是截图。

​

​

正如你可以从截图中看到的，有一个黑色的背景，当应用程序启动时，我的整个视图没有显示在全屏上。

应该是下面的样子。

​

​

在点击按钮时，侧视显示如下所示。

​

​

它应该是小的，因为我已经采取了宽度= 300和高度= 768的视图大小。

但它显示出的比这更大。

以下是我在应用程序委托中更改的代码。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    [self createEditableCopyOfDatabaseIfNeeded];

    // Override point for customization after application launch.
    self.viewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];

    UINavigationController *navController = [[UINavigationController alloc]initWithRootViewController:self.viewController];

    SlidingViewController *slidingView = [[SlidingViewController alloc]initWithNibName:@"SlidingViewController" bundle:nil];

    self.slideMenuController = [[SlideMenuController alloc] initWithCenterViewController:navController];
    self.slideMenuController.leftViewController = slidingView;

    self.window.rootViewController = navController;
    [self.window makeKeyAndVisible];
   return YES;
}

- (IBAction)sideBarPressed:(id)sender
{
    AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
    if (appDelegate.slideMenuController.position == TKSlidePositionCenter) {
        [appDelegate.slideMenuController presentLeftViewControllerAnimated:YES];
    } else {
        [appDelegate.slideMenuController presentCenterViewControllerAnimated:YES];
    }
}

我只想为我的iPad 景观模式这样做。

请告诉我这里出了什么问题？

我被困在这里好长一段时间。

任何帮助都将不胜感激。

提前谢谢。

Answer 1

我用这个演示代码成功地实现了这个边栏菜单功能，在我的例子中它工作得很好。

希望它对其他人也有用。

谢谢你的帮助和建议。

所以更好的你需要使用UISplitViewController

 //in app delegate do like this
 //in appDelegate.h file 
 #import <UIKit/UIKit.h>

 @interface AppDelegate : UIResponder <UIApplicationDelegate>

 @property (strong, nonatomic) UIWindow *window;
 @property (nonatomic, retain) UISplitViewController *splitViewCOntroller; 
 @end


 //in appDelegate.m file
 #import "AppDelegate.h"
 #import "SplitMasterViewController.h"  //create a UITableviewController 
 #import "SplitViewDetailController.h"  //create a UIViewController

  @implementation AppDelegate
  @synthesize splitViewCOntroller = _splitViewCOntroller;

  - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
   {
      // Override point for customization after application launch.
      SplitMasterViewController *masterController  = [[SplitMasterViewController alloc]initWithNibName:@"SplitMasterViewController" bundle:nil]; //this is the master menu controller

     UINavigationController *masterNavController = [[UINavigationController alloc]initWithRootViewController:masterController];

     SplitViewDetailController *detailViewController = [[SplitViewDetailController alloc]initWithNibName:@"SplitViewDetailController" bundle:nil]; //this is the master detail controller


     UINavigationController *detailNavController = [[UINavigationController alloc]initWithRootViewController:detailViewController];
masterController.detailViewController = detailViewController;

    _splitViewCOntroller = [[UISplitViewController alloc]init]; //initilise split controller
    _splitViewCOntroller.delegate = detailViewController;      //set the delegate to detail controller
    _splitViewCOntroller.viewControllers = [NSArray arrayWithObjects:masterNavController,detailNavController, nil]; //set the splitview controller
     self.window.rootViewController = _splitViewCOntroller; //finally your splitviewcontroller as the root view controller
     [self.window makeKeyAndVisible];

     return YES;
 }


 //in SplitMasterViewController.h this must be a table that contains your side bar menu items 
 #import "ViewController.h" //comment this if it shows any error
 #import "SplitViewDetailController.h"

 @interface SplitMasterViewController :        UITableViewController<UITableViewDataSource,UITableViewDelegate>
 @property (nonatomic, retain) SplitViewDetailController *detailViewController; //to get the detailview from masterMenu controller 
 @property (nonatomic, retain) NSArray *Names;

 @end 

 // in SplitMasterViewController.m file
 #import "SplitMasterViewController.h"
 #import "SplitViewDetailController.h"


 @interface SplitMasterViewController ()

 @end

 @implementation SplitMasterViewController
