将 BarButtonItem 添加到模态导航视图控制器

发布于 2024-09-16 15:51:26 字数 1039 浏览 4 评论 0原文

我正在展示一个用根控制器(即 UITableViewController)初始化的模式导航栏控制器。当我初始化 UINavigationBarController 以以模态方式呈现它时,我还添加了一个“提交”按钮作为右栏按钮项。一切工作正常(加载根视图和模态演示)但是,右侧按钮未显示。 发布下面的代码 -

-(IBAction) presentAddLeaveRequestModally {
    AddLeaveRequestViewController *leaveRequestViewController = [[AddLeaveRequestViewController alloc] init];
    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:leaveRequestViewController];
    UIBarButtonItem *submitButton = [[UIBarButtonItem alloc] initWithTitle:@"Submit" 
                                                                     style:UIBarButtonItemStyleBordered
                                                                     target:self 
                                                                     action:@selector(submitLeaveRequest)];
    navController.navigationItem.rightBarButtonItem = submitButton;
    [self.homeTabBarController presentModalViewController:navController animated:YES];
}

如果我遗漏了一些明显的东西,有什么想法吗?

I am presenting a modal navigation bar controller initialized with a root controller (which is a UITableViewController). When I, initialize the UINavigationBarController to present it modally, I am also adding a "Submit" button as a right bar button item. Everything is working fine (loading with root view and Modal presentation) However, the right button is not showing.
Posting the code below -

-(IBAction) presentAddLeaveRequestModally {
    AddLeaveRequestViewController *leaveRequestViewController = [[AddLeaveRequestViewController alloc] init];
    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:leaveRequestViewController];
    UIBarButtonItem *submitButton = [[UIBarButtonItem alloc] initWithTitle:@"Submit" 
                                                                     style:UIBarButtonItemStyleBordered
                                                                     target:self 
                                                                     action:@selector(submitLeaveRequest)];
    navController.navigationItem.rightBarButtonItem = submitButton;
    [self.homeTabBarController presentModalViewController:navController animated:YES];
}

Any ideas if I am missing something obvious?

遇到问题了...正在将 rightBarButtonItem 添加到 navController 的 navigationItem ...我应该将其添加到 viewDidLoad 中 rootViewController 的 navigationItem 中。

UIBarButtonItem *submitButton = [[UIBarButtonItem alloc] initWithTitle:@"Submit" 
                                                                 style:UIBarButtonItemStyleBordered
                                                                 target:self 
                                                                 action:@selector(submitLeaveRequest)];
self.navigationItem.rightBarButtonItem = submitButton;

Got the problem ... was adding rightBarButtonItem to navController's navigationItem ... I should be adding it to rootViewController's navigationItem in viewDidLoad.

UIBarButtonItem *submitButton = [[UIBarButtonItem alloc] initWithTitle:@"Submit" 
                                                                 style:UIBarButtonItemStyleBordered
                                                                 target:self 
                                                                 action:@selector(submitLeaveRequest)];
self.navigationItem.rightBarButtonItem = submitButton;
