页面控制器和导航栏

Question

我的问题是没有在我的控制器中显示第一个视图的导航栏标题。 对于下一个项目，文本正在显示。 我的代码：

ViewControllerEvent *initialViewController = [self viewControllerAtIndex:self.index];
NSArray *viewControllers = [NSArray arrayWithObject:initialViewController];
[self.pageController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];

和 ViewController 代码：

- (void)viewDidAppear:(BOOL)animated{
    self.navigationController.navigationBar.topItem.title = [self.event objectForKey:@"name"];
}

Answer 1

试试这个

- (void)viewDidAppear:(BOOL)animated{
    [super viewDidAppear:animated];
    self.navigationController.title = [self.event objectForKey:@"name"];
}
