I have an app with navigation controller, but my app also has a simple separate view which is not a navigation controller part. And what I want to do is to add a brand new navigation controller to this view.
For my first navigation controller I used this code in my AppDelegate:
UINavigationController *navigationController = [[UINavigationController new] initWithRootViewController:viewController1];
navigationController.viewControllers = [NSArray arrayWithObject:viewController1];
self.window.rootViewController = navigationController;
But which code I should use, if I want to create a new Navigation Controller ?
Thanks !
UPDATE:
So, I made some pictures:
One the first pic there is a navigation controller (which is declared in AppDelegate). And It contains an info button. Then, when we press the button we move to another view (pic 2). And its just a navigation bar in this view, not an navigation controller. I wanna add a navigation controller, not a navigation bar in this view, so users will be able to use UITableView easily
We would need to know a little more about your intended view hierarchy, and application flow. But in the code you're posting, I'm not sure what is going on. Why not just:
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController1];
self.window.rootViewController = navController;
That said, you would create other UINavigationControllers exactly the same way.
Update:
When you press the info button on the first view, you could present the navigation controller modally I think.
- (IBAction)infoButtonAction:(id)sender;
{
// InfoTableViewController is the controller with Instructions, Contact, and something else
// my Russian isn't so good.
InfoTableViewController *tableController = [[InfoTableViewController alloc] initWithStyle:UITableViewStyleGrouped];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:tableController];
navController.modalPresentationStyle = UIModalPresentationFormSheet; // or whatever
[self presentModalViewController:navController animated:YES];
}
Note that I'm not dealing with memory management because I don't know if this is ARC or not. Is that how it should behave?

I'm beginner iOS developer, so don't know how to solve my problem correctly. I have one navigation controller and want to make modal transition to another navigation controller that will have back button on it's first view controller.
In my first navigation controller I made this:
InfoViewController *destinatinViewController = [[InfoViewController alloc] initWithNibName:#"InfoViewController" bundle:nil];
[self presentViewController:destinatinViewController animated:YES completion:nil];
InfoViewController is UINavigationViewController.
Then I made this in InfoViewController (second navigation controller):
InfoRootViewController *rootViewController = [[InfoRootViewController alloc] initWithNibName:#"InfoRootViewController" bundle:nil];
[self pushViewController:rootViewController animated:NO];
For now I know how to add button to go back, but it has not styling (certainly arrow). As I understand because it is only one view in stack of second navigation controller.
So, I need your help to add styled back button for first view controller of navigation controller, because I don't want to make own styling (I'm lazy).
Thanks, for any advance!
PS: I made modal transition because, it has animations like from bottom or top. I tried to use custom animations for pushViewController, but in iOS 7 they're working not correctly.
I'll let someone else help you with the back button issue because I think it's a mistake to create one for a modal view controller that's presented from the bottom of the screen. Typically, such a modal view controller is dismissed with a cancel button or its equivalent. If you really think that you need a back button then you should probably push the view controller onto the existing navigation stack instead of presenting it modally.
However, I am happy to show you how to properly alloc/init a navigation controller and then present it.
I don't know why you're subclassing UINavigationController, but I'm going to pretend that you don't need to (which is probably the case).
InfoRootViewController *rootViewController = [[InfoRootViewController alloc] initWithNibName:#"InfoRootViewController" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:rootViewController];
[self presentViewController:navController animated:YES completion:nil];
In my codes, I wrote it in this way
DetailView *vc = (DetailView *)[mainStoryboard instantiateViewControllerWithIdentifier:#"DetailVC"];
self.window.rootViewController = vc;
It only show that view but I don't see the navigational bar and tab bar.
What is the right way to open a specific view (inside tabbarcontroller) within storyboard when the app receive remote notifications automatically?
That's because you get only DetailView from storyboard. If you want to show it inside navigation controller you have to init this controller.
DetailView *vc = (DetailView *)[mainStoryboard instantiateViewControllerWithIdentifier:#"DetailVC"];
UINavigationController *navVC = [[UINavigationController alloc] initWithRootViewController: vc];
self.window.rootViewController = navVC;
But I think the issue is in other. You instantiate wrong view controller. You should instantiate tab bar controller or navigation controller and then only select proper tab.
Presenting an instance of FBFriendPickerViewController using presentViewController:animated:completion: is pretty straightforward and the class seems like it is meant for that use case. However, I want to push an instance of FBFriendPickerViewController onto an instance of UINavigationController using pushViewController:animated:.
Consider the following code as an example:
self.fbFriendPickerController = [[FBFriendPickerViewController alloc] init];
self.fbFriendPickerController.hidesBottomBarWhenPushed = YES;
// configure stuff
[[self navigationController] pushViewController:self.fbFriendPickerController animated:YES];
However, the problem is that the instance of FBFriendPickerViewController already has a top navigation bar. When pushed onto a UINavigationController, this results in two top navigation bars stacked vertically, as you can see in the screenshot below.
One solution would be to hide the top nav bar of the UINavigationController, but that creates an awkward transition and there is no back button. Any thoughts on the best way to keep the UINavigationController top nav bar but the hide the FBFriendPickerViewController top nav bar?
After looking through the Facebook iOS SDK source code on Github, I figured this out. FBFriendPickerViewController is a subclass of FBViewController. If you set the doneButton and cancelButton properties of any FBViewController to nil, FBViewController will remove the top navigation bar. As a result, the following code works:
self.fbFriendPickerController = [[FBFriendPickerViewController alloc] init];
self.fbFriendPickerController.hidesBottomBarWhenPushed = YES;
self.fbFriendPickerController.doneButton = nil;
self.fbFriendPickerController.cancelButton = nil;
// configure stuff
[[self navigationController] pushViewController:self.fbFriendPickerController animated:YES];
I have an aplication which initially there's a TabBarController, each tab is a ViewController and every one has a button which calls other controllers.
So how am I supose to structure this? Having one main rootviewController (if so, how?)? Or calling in the appdelegate only the tabBarController and in each the viewControllers inside the tab call the other controllers?
What's the best way so I can advance, go back and transition views nimbly?
Don't know if I made myself clear...
Thanks guys.
Generally you will start with the Template called "Tab Bar Application" and as of Xcode 4 starts by loading the MainWindow Nib, which hold a tab bar and the tab bar is set up in IB to have 2 view controllers, called "FirstViewController", and "SecondViewController"...
You can follow that pattern if it suites you, otherwise you may want to start with a view based application and add your own tab bar. I personally find it to be easier to control the tab bar, through the UITabBarDelegate, especially if you plan to do anything slightly esoteric.
Edit:
Basically one of two ways, if you plan to load a Navigation controller stack, or a single modal view.
1)
ThirdViewController * controller = [[ThirdViewController alloc] initWithNibName:#"ThirdViewController" bundle:nil];
UINavigationController * myNavigationController = [[UINavigationController alloc] initWithRootViewController:controller];
[self presentModalViewController:myNavigationController animated:YES];
[controller release];
[myNavigationController release];
2)
ThirdViewController * controller = [[ThirdViewController alloc] initWithNibName:#"ThirdViewController" bundle:nil];
[self presentModalViewController:controller animated:YES];
[controller release];
either way get back to the Tab environment by calling the following on the view controller that is calling present modal.
[self
dismissModalViewControllerAnimated:YES];
I am building an app, which has TabBarController, and each tab view has navigation view controller. When user click tab, I'd like the relavent navigation view controller to "reset" to the root panel.
In my code, I uses the following way to initialize the tab and navigation controller.
viewController1 = [[MyFirstController alloc] init];
UINavigationController *tableNavController = [[[UINavigationController alloc] initWithRootViewController:viewController1] autorelease];
viewController2 = [[MySecondController alloc] init];
UINavigationController *table2NavController = [[[UINavigationController alloc] initWithRootViewController:viewController2] autorelease];
tabBarController.viewControllers = [NSArray arrayWithObjects:tableNavController, table2NavController, nil];
Then appears that all the tab and navigation controller is working automatically. I am not sure where to cut in to let navigation controller view to reset when it is selected.
Thanks.
The navigation controller is sent a viewWillAppear message by the system, so you can implement the method to do the resetting..
Another option would be to use the tab bar controller's selectedViewController method to retrieve the selected navigation controller..
Hope that helps..
