PresentViewController iOS上的PushView

我想

在
PresentViewController

当我最初点击按钮时，我正在加载
PresentViewController
，下面是我的代码

- (IBAction)JoinClicked:(id)sender{

    JoinWithViewController *detail_view_controller = [[JoinWithViewController alloc] initWithNibName:@"JoinWithViewController" bundle:nil];
    [self.view.window.rootViewController presentViewController:detail_view_controller
                                                      animated:YES
                                                    completion:NULL];

}

这很好，但当我单击单击上的按钮时，
PresentViewController
on click我想按我的视图，但in不按

请帮忙，提前谢谢。

JoinWithViewController *detail_view_controller = [[JoinWithViewController alloc] initWithNibName:@"JoinWithViewController" bundle:nil];
[self.navigationController pushViewController:detail_view_controller animated:YES];

按此方式尝试推送viewController。如果使用TabBar，请在AppDelegate中执行此操作。如果您创建了选项卡栏，拖放意味着离开。按如下编程方式创建选项卡栏

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    UITabBarController *tabController = [[UITabBarController alloc]init];

    self.viewController = [[CalculatorViewController alloc] initWithNibName:@"CalculatorViewController" bundle:nil];
    UITabBarItem *tab_item1 = [[UITabBarItem alloc]init];
    //tab_item1.title = @"Calculator";
    tab_item1.image = [UIImage imageNamed:@"Calculator.png"];
    [self.viewController setTabBarItem:tab_item1];
    UINavigationController *nav1 = [[UINavigationController alloc]initWithRootViewController:self.viewController];

    ShowPhoneViewController *phone = [[ShowPhoneViewController alloc]init];
    UITabBarItem *tab_item2 = [[UITabBarItem alloc]init];
    tab_item2.title = @"Latest Mobiles";
    tab_item2.image = [UIImage imageNamed:@"Mobile.png"];
    [phone setTabBarItem:tab_item2];
    UINavigationController *nav2 = [[UINavigationController alloc]initWithRootViewController:phone];

    CurrencyConvertorViewController *currency = [[CurrencyConvertorViewController alloc]init];
    UITabBarItem *tab_item3 = [[UITabBarItem alloc]init];
    tab_item3.title = @"Units Convertor";
    tab_item3.image = [UIImage imageNamed:@"Dollar.png"];
    [currency setTabBarItem:tab_item3];
    UINavigationController *nav3 = [[UINavigationController alloc]initWithRootViewController:currency];

    SettingsPageViewController *setting = [[SettingsPageViewController alloc]init];
    UITabBarItem *tab_item4 = [[UITabBarItem alloc]init];
    tab_item4.title = @"Settings";
    tab_item4.image = [UIImage imageNamed:@"Settings.png"];
    [setting setTabBarItem:tab_item4];
    UINavigationController *nav4 = [[UINavigationController alloc]initWithRootViewController:setting];


    tabController.viewControllers = [NSArray arrayWithObjects:nav1, nav2, nav3, nav4, nil];
    self.window.rootViewController = tabController;

    [self.window makeKeyAndVisible];
    return YES;
}

我希望您现在有了
推送视图控制器是UINavigationController的功能，您可以在另一个vierw控制器上推送一个视图控制器。在这里，您使用单个viewcontroller作为根viewcontroller，因此您必须将根viewcontroller更改为UINavigationcontroller，或者可以使用“添加子视图方法””在当前viewcontroller上添加新的viewcontroller

但是更好的选择是添加uinavigationcontroller作为rootviewcontroller

AppDelegate.m

-（BOOL）应用程序：（UIApplication*）应用程序使用选项完成启动：（NSDictionary*）启动选项{

     FirstViewController *first = [[FirstViewController alloc]
                                 initWithNibName:@"FirstViewController" bundle:nil];
     UINavigationController *navController =[[UINavigationController alloc] 
                                            initWithRootViewController:first];
     [self.window setRootViewController:navController];   

}

现在，当您要在单击按钮时从FirstViewController切换到SecondViewController时，必须使用pushviewcontroller

FirstViewController.h

：如何在appDelegate中初始化rootViewController请输入您的代码。
appDelegate
中没有任何内容。我正在使用StroyBoardy。您还可以使用CATTransition将视图与动画的持续时间合并。你知道这方面的例子吗？即使你使用故事板，你也需要使用选项完成启动：self.viewController=[[viewcontrolleralloc]initWithNibName:@“viewController”bundle:nil]；UINavigationController*nav=[[UINavigationController alloc]initWithRootViewController:self.viewController]；self.window.rootViewController=nav；要按ViewController，当我在
中编写代码并使用选项完成启动时，我无法看到底部的
选项卡栏
1。在Appdelegte.m中，您可以将导航控制器添加为rootviewcontroller（这里FirstViewController是UINavigationController的rootviewcontroller）。2.（当您不使用故事板时）现在假设在按下“下一步”按钮时，您希望从FirstViewController切换到SecondViewController，而不是必须调用nextBtnPressed方法。@Krunal:您得到了想要的输出吗？
-(void) nextBtnPressed {
    SecondViewController *second = [[SecondViewController alloc]  initWithNibName:@"SecondViewController" bundle:nil];
     [self.navigationController pushViewController:second animated:TRUE];
 }
