UISplitViewController

UISplitViewController隻能用于iPad上

APPDelegate

• (BOOL)application:(UIApplication )application didFinishLaunchingWithOptions:(NSDictionary )launchOptions {

  // Override point for customization after application launch.

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

  [self.window makeKeyAndVisible];

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

  TQTableViewController *tableViewVC = [[TQTableViewController alloc] initWithStyle:0];

  ViewController *vc = [[ViewController alloc] init];

  UINavigationController *vcNav = [[UINavigationController alloc] initWithRootViewController:vc];

  tableViewVC.delegate = vc;

  splitVC.viewControllers = @[tableNav,vcNav];

  splitVC.delegate = vc;

  self.window.rootViewController = splitVC;

  return YES;

  }

//是否隐藏左邊的菜單

//- (BOOL)splitViewController:(UISplitViewController )svc shouldHideViewController:(UIViewController )vc inOrientation:(UIInterfaceOrientation)orientation

//{

// return NO;

ViewController

• (void)viewDidLoad {

  [super viewDidLoad];

  // Do any additional setup after loading the view, typically from a nib.

  //系統寫好一個事件響應的對象 以及事件響應的方法

  self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@”menu” style:0 target:self.splitViewController.displayModeButtonItem.target action:self.splitViewController.displayModeButtonItem.action];

  self.webView = [[UIWebView alloc] initWithFrame:self.view.bounds];

  [self.view addSubview:self.webView];

  }

-(void)setWebViewContent:(NSString *)urlStr

{

[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:urlStr]]];

}

//改變顯示模式的時候會調用該代理方法

- (void)splitViewController:(UISplitViewController *)svc willChangeToDisplayMode:(UISplitViewControllerDisplayMode)displayMode

{

if(displayMode == UISplitViewControllerDisplayModeAllVisible)

{

self.navigationItem.leftBarButtonItem = nil;

}

else

{

self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@”menu” style:0 target:self.splitViewController.displayModeButtonItem.target action:self.splitViewController.displayModeButtonItem.action];

}

}
