iphone - 如何为具有 splitview Controller 的应用程序提供登录屏幕？

Question

当我将 UISplitviewController 指定为应用程序的 Rootview 时，当时工作正常，但现在我想将登录屏幕添加到我的应用程序。有人可以帮助我吗？提前谢谢。

您可以将您的 LoginViewcontroller 添加为 Delegate 中的 Root View Controller ，并在 LoginScreen loginbutton 操作检查用户名或密码，如果它为真，那么您必须创建您的 Delegate 对象并将 rootviewconteroller 设置为您的 splitviewcontroller。就像我的波纹管代码:-

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{


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

    self.viewController = [[LogInViewController alloc] initWithNibName:@"LogInViewController" bundle:nil];


     self.window.rootViewController = self.viewController;

       [self.window makeKeyAndVisible];
    return YES;

}

和你的 loginButton Action :

-(IBAction)loginclick:(id)sender
{
     objAppdelegate = (yourProjectnameDelegate *) [[UIApplication sharedApplication]delegate];
     NSMutableArray *array = [NSMutableArray array];

                HomeSpilitView = [[[UISplitViewController alloc] init]autorelease];

                HomeMster = [[HomeSpilitViewController alloc] initWithNibName:@"HomeSpilitViewController" bundle:nil];

                masterNavigationController = [[[UINavigationController alloc] initWithRootViewController:HomeMster] autorelease];
                HomeMster.title=@"Title home";
                masterNavigationController.navigationBar.tintColor =[UIColor colorWithRed:255/255.0 green:108/255.0 blue:61/255.0 alpha:0.1];
                [array addObject:masterNavigationController];


                HomeDetailsViewController *HomeDetailsViewControllers = [[HomeDetailsViewController alloc] initWithNibName:@"HomeDetailsViewController" bundle:nil];

                detailNavigationController = [[[UINavigationController alloc] initWithRootViewController:HomeDetailsViewControllers] autorelease];

                detailNavigationController.navigationBar.tintColor =[UIColor colorWithRed:255/255.0 green:108/255.0 blue:61/255.0 alpha:0.1];
                HomeDetailsViewControllers.title=@"details title";
                HomeMster.objHomeDetailsViewcontroller=HomeDetailsViewControllers;
                HomeSpilitView.delegate = HomeDetailsViewControllers;

              [array addObject:detailNavigationController];

              [HomeSpilitView setViewControllers:array];

              [objAppdelegate.window setRootViewController:HomeSpilitView];


}

更新最后我使用波纹管代码完成了它:-

 UIInterfaceOrientation interfaceOrientation = HomeSpilitView.interfaceOrientation;
    NSString *subtypeDirection;
    if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft) {
        subtypeDirection = kCATransitionFromTop;
    }
    else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight) {
        subtypeDirection = kCATransitionFromBottom;
    }
    else {
        subtypeDirection = kCATransitionFromRight;
    }
    [objAppdelegate.window setRootViewController:HomeSpilitView];
    CATransition *animation = [CATransition animation];
    [animation setDuration:0.5];
    [animation setType:kCATransitionPush];
    [animation setSubtype:subtypeDirection];
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];

    [[objAppdelegate.window layer] addAnimation:animation forKey:@"SwitchToView1"];
