I have UIViewController with tabbar botton, and navigation bar and navigation item,
when I press on my button in navigation Item I want to load a view, I don't know how to load this view on tabbar,
would you please help me,thanks in advance!
-(IBAction) infoPage:(id)sender
{
InfoCtrol *i = [[InfoCtrol alloc] initWithNibName:#"InfoCtrol" bundle:nil];
[self.navigationController pushViewController:i animated:YES];
}
This will load the InfoCtrol controller and set the Touch UpInside Event in xib to the infoPage method
Do you mean you want to hide the tab bar when you push new controller in navigation?
If true. There is a property hidesBottomBarWhenPushed in the UIViewController class.
// Instead of adding ViewController to TabbarController, add NavigationControllers.
// Eg.
UINavigationController *NavController = [[UINavigationController alloc] initWithRootViewController:_viewCtrl1];
[watchListNavController.navigationBar setTintColor:[UIColor blackColor]];
_tabC = [[UITabBarController alloc] init];
_tabCt.viewControllers = [NSArray arrayWithObjects:NavController,_viewCtrl2,_viewCtrl3, nil];
// Now you can use Push and Pop In your _viewCtrl1.
// Do same with all the viewController

For my code structure:
On AppDelegate, I declared 4 UINavigationController with their own root UIViewController for my UITabBar.
I created one custom UIViewController as template, in where my other UIViewControllers are sub-class.
On my template:
I have my rightBarButtonItem to show current user profile.
// public method added on template
- (void) goToProfile {
NSLog(#"going through...");
ProfileViewController *ctrl = [[ProfileViewController alloc] init];
[self.navigationController pushViewController:ctrl animated:YES];
}
For my leftBarButtonItem:
- (void) goBack {
[self.navigationController popViewControllerAnimated:YES];
}
First click on the rightBarButtonItem, works fine. If I click the leftBarButtonItem to go back then re-click the rightBarButtonItem, it won't work anymore.
In addition, I have a button on one of my UIViewController that is calling the public method goToProfile. And that works fine.
I got help from my co-worker. The approach is something similar to #Vidhyanand900 answer. I hope this will help others in the future.
tabbarSelectedIndex = 1; // profile tab index
ProfileViewController *ctrl = [[ProfileViewController alloc] init];
UINavigationController *navController = [_appDelegate.mainTabBarController.viewControllers objectAtIndex:tabbarSelectedIndex];
[navController pushViewController:ctrl animated:YES];
self.mainTabBarController.selectedIndex = tabbarSelectedIndex;
If you are pushing or popping with UINavigation controllers of UITabBar
Else show UINavigation Controllers inside UITab Bar..i.e; Is Profile View controller is part of UITab bar or not..
Then you need to change the index of tab bar as below
self.tabBarController.selectedIndex=0;//if profile is first tab
ProfileViewController *ctrl = [[ProfileViewController alloc] init];
[self.navigationController pushViewController:ctrl animated:YES];
Hope it helps you...
I'm new to Objective-C and I want to add a UINavigationBar on my CatrgoryBIDViewController. I have proceed UIButton in InstructionBIDViewController.m file that should navigate to CatrgoryBIDViewController. Here is the function code:
- (IBAction)proceed:(id)sender {
viewControllercat =
[[CatrgoryBIDViewController alloc]
initWithNibName:#"CatrgoryBIDViewController"
bundle:nil];
UINavigationController *nav =
[[UINavigationController alloc]
initWithRootViewController:self.viewControllercat];
//[self.navigationController pushViewController:viewControllercat animated:YES];
[self.navigationController setNavigationBarHidden:NO animated:YES];
}
But it is not setting the UINavigationBar.
You should read the documentation here to understand the way a NavigationController is working. For your case:
If your current ViewController (where your proceed-method is implemented) has a NavigationController (is child of it), you can push another ViewController onto the stack of that NavigationController with
[self.navigationController pushViewController:viewControllercat animated:YES];
In this case you do not need to initialize another NavigationController, but in your CatrgoryBIDViewController in viewWillAppear you need to make the NavigationBar visible if it was not before already with
[self.navigationController setNavigationBarHidden:NO animated:YES];
If your current ViewController does not have a NavigationController, you can not push another ViewController on top of it and can not show the NavigationBar of it (although you can create your own NavigationBar and add it to the View of the ViewController, but without the usual Navigation-behaviour embedded).
If you open your ViewController programmatically (e. g. from the AppDelegate) you are correct to do so by your call:
viewControllercat = [[CatrgoryBIDViewController alloc] initWithNibName:#"CatrgoryBIDViewController" bundle:nil];
UINavigationController *nav=[[UINavigationController alloc] initWithRootViewController:self.viewControllercat];
My apologies - After having reread your question, I am going to tweak my answer some.
-(IBAction)proceed:(id)sender
{
viewControllercat = [[CatrgoryBIDViewController alloc] init];
UINavigationController * nc =
[[UINavigationController alloc] initWithRootViewController:vc];
// We now need to display your detail view but cannot push it.
// So display modally
[self presentViewController:nc animated:YES completion:Nil];
}
The above should result in your DetailViewController - CategoryBIDViewController being displayed on top of your InstructionBIDViewController and it should have a UINavigationController in it.
I have a navigation controller which has view controller(VC1) . This view controller has 3 button out of which 1 directs to a tab bar controller. From tab1 of the tab bar controller a button is there which navigates to a View controller(vc2).
The problem is VC2 is not displaying the tab bar. How can I make my VC2 display the tab bar.
Navigation Controller—> View Controller-->Tab bar Controller —>Tab1 -> View Controller (does not show tab bar)
I am doing this in IOS
Using a tabbarcontroller within a navigation controller is not recommended by Apple. However it is possible to do so.
In the VC1, write the following code.
UITabBarController *tabBarController = [[UITabBarController alloc] init];
MyStartViewController *startController = [[MyStartViewController alloc] initWithNibName:#"MyStartViewController" bundle:Nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:startController];
SecondViewController *viewController2 = [[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil];
self.viewControllers = #[navController, viewController2];
[self.navigationController pushViewController:tabBarController animated:YES];
Now within startController, add a UIButton. And in the button action, push the new VC2 from it.
Button action:
- (IBAction)buttonPressed {
MyViewController2 *vc2 = [[MyViewController2 alloc] initWithNibName:#"MyViewController2" bundle:nil];
[self.navigationController pushViewController:vc2 animated:YES];
}
Hope this will serve your purpose.
Having one main navigation controller in whole application and also one main tabbarcontroller , problem is that when i click om 'more' tab of tabbarcontroller at that time it's showing two navigation bars
to solve this problem i tried to hide my main navigation controllers navigationbar using following code :
self.tabbar.navigationController.navigationBarHidden =YES;
but doing this gives me unexpected result in the form of half navigationbar with half black background.
if any one knows the solution then please help me.
thanks in advance.
make viewController With separate UINavigationController,
put this code in Appdelegate
ViewController *a = [[ViewController alloc] initWithNibName:#"a" bundle:nil];
ViewController *b= [[CreateMeetingViewController alloc] initWithNibName:#"b" bundle:nil];
ViewController *c = [[SettingsViewController alloc] initWithNibName:#"c" bundle:nil];
UINavigationController *nav_1 = [[UINavigationController alloc] initWithRootViewController:a];
UINavigationController *nav_2 = [[UINavigationController alloc] initWithRootViewController:b];
UINavigationController *nav_3 = [[UINavigationController alloc] initWithRootViewController:c];
MainTabBar = [[UITabBarController alloc] init];
MainTabBar.delegate = self;
[MainTabBar setViewControllers:[NSArray arrayWithObjects:nav_1,nav_2,nav_3,nil]];
MainTabBar.view.frame=self.view.frame;
[self.view addSubview:MainTabBar.view];
You can check your .Xib you check the option Top Bar this should be 'None' in the identity inspector.
Write in viewWillAppear, i hope it will be helpful for you
[self.navigationController setNavigationBarHidden:YES animated:YES];
I am using UITabbarController which has three child UIViewController named as FirstViewController, SecondViewController, ThirdViewController. I have a button on FirstViewController. When we tap the button, it need to push navigate to FourthViewController. Here the FourthViewController navigate inside UITabBarController itself. But i need it navigate out of UITabBarController not inside.
Button Target Action
ForthViewController *share = [[ForthViewController alloc] init];
[self.navigationController pushViewController:share animated:YES];
Could anyone guide me for right way. Thanks in Advance..
Try this:
ForthViewController *share = [[ForthViewController alloc] init];
[self.parentViewController.navigationController pushViewController:share animated:YES];
As long as your tab bar controller is in a navigation controller, this will push your view controller on that navigation stack.
