ios - PresentViewController iOS 上的 PushView

Question

我要 Push我在 PresentViewController 上的 View Controller

当我最初单击按钮时，我正在加载 PresentViewController ，这是我的代码。

- (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];

}

这很好用，但是当我单击 PresentViewController 上的按钮时单击时我想推送我的 View ，但不推送。

请帮助，在此先感谢。

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

尝试像这样推送 viewController。如果您使用 TabBar，请在 中执行此操作应用委托(delegate) .如果您创建 TabBar 拖放意味着离开。以编程方式创建 TabBar，如下所示。

- (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;
}
