导航栏不更改视图

Question

我正在做一个带有导航栏的应用程序，它将在第一个和第三个视图之间切换（第二个和第一个将由选项卡栏切换）。

在FirstViewController.h中：

@property(strong,nonatomic) ThirdViewController *thirdViewController;

在FirstViewController的viewDidLoad方法中，我做到了：

self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Model"
style:UIBarButtonItemStylePlain target:self action:@selector(goToThirdView:)];

还有...

- (void)goToThirdView:(id)sender
{
    ThirdViewController *thirdViewController = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController" bundle:nil];
    self.thirdViewController = thirdViewController;   
    [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:YES];
    [self.view removeFromSuperview];
    [self.view insertSubview:self.thirdViewController.view atIndex:0];
    [UIView commitAnimations];
}

我的应用程序代表看起来像这样：

UIViewController *viewController1 = [[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil];
UINavigationController *navigationController1 = [[UINavigationController alloc] initWithRootViewController:viewController1];
UIViewController *viewController2 = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:navigationController1, viewController2, nil];
self.window.rootViewController = self.tabBarController;

但是它不起作用，当我单击按钮时，没有任何反应。知道吗？提前谢谢你。

您应该将

按钮的选择器保留为 goToThirdView：，但使该方法如下所示：

- (void)goToThirdView:(id)sender {
    ThirdViewController *thirdViewController = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController" bundle:nil];
    [self.navigationController pushViewController:thirdViewController animated:YES];
}
