self.navigationController pushViewController无法正常工作 [英] self.navigationController pushViewController not working

问题描述

我有一个带有单个 UIViewController 的View应用程序。然后我通过IB添加一个 UITableViewController ，我试图通过<按下按钮显示 UITableViewController code> UIViewController （我的主要观点）。我按下按钮（IBAction）包含以下代码，我试图通过该代码推送我的 UITableViewController 视图并显示它：

I have a View application with a Single UIViewController. I then add a UITableViewController through the IB, and I am trying to display the UITableViewController through a button press in the UIViewController (my main view). My button press (IBAction) contains the following code through which I am trying to push my UITableViewController view and display it:

DataViewController *dataController = [[DataViewController alloc] initWithNibName: @"DataViewController" bundle:nil];
[self.navigationController pushViewController:dataController animated:YES];
[dataController release];

我的 DataViewController 根本没有得到推动进入堆栈并显示，
我也检查过上面的代码， self.navigationController = nil
可能这是问题的根源。如果是这样，如何纠正它？

My DataViewController is not at all getting pushed into the stack and displayed, Also I have checked that in the code above, self.navigationController=nil Probably this is the source of the problem. If so, how to rectify it?

请帮忙。

推荐答案

UINavigationController *navCtrlr = [[UINavigationController alloc]initWithRootViewController:yourfirstviewController];
[self.window setRootViewController:navCtrlr];
navCtrlr.delegate = self;
navCtrlr.navigationBarHidden = YES;

在 appdelegate.m 中创建导航控制器然后你可以导航到任何 uiviewcontroller

Create navigation controller in appdelegate.m then you can navigate to any uiviewcontroller
