I have a tab bar controller with three tabs that I set programmatically. The two first ones are just UIViewController but the third one is an UISplitViewController that I get from another storyboard. Everything works great but when I'm on portrait mode and show the master view, this one is showed on top of the tab bar. I would like keep showing the full tab bar.
This also generate problems when trying to show an UIAlertController from an item bar button in the master view (this button doesn't exist in the image) as the popover is showed behind the master view.
Does anyone know how can I workaround this?
The way I set them programmatically is this (in case it may help):
UIViewController *view1 = [[UIStoryboard storyboardWithName:#"Main" bundle:nil] instantiateViewControllerWithIdentifier:#"FirstView"];
UIViewController *view2 = [[UIStoryboard storyboardWithName:#"Main" bundle:nil] instantiateViewControllerWithIdentifier:#"SecondView"];
UIViewController *view3 = [[UIStoryboard storyboardWithName:#"StoryboardSplit" bundle:nil] instantiateViewControllerWithIdentifier:#"MySplitView"];
UISplitViewController *splitViewController = (UISplitViewController *)view3;
UINavigationController *navigationController = [splitViewController.viewControllers lastObject];
navigationController.topViewController.navigationItem.leftBarButtonItem = splitViewController.displayModeButtonItem;
splitViewController.delegate = self;
NSMutableArray *tabViewControllers = [[NSMutableArray alloc] init];
[tabViewControllers addObject:view1];
[tabViewControllers addObject:view2];
[tabViewControllers addObject:splitViewController];
[self setViewControllers:tabViewControllers];
view1.tabBarItem =
[[UITabBarItem alloc] initWithTitle:#"view1"
image:[UIImage imageNamed:#"view1"]
tag:1];
view2.tabBarItem =
[[UITabBarItem alloc] initWithTitle:#"view2"
image:[UIImage imageNamed:#"view2"]
tag:2];
view3.tabBarItem =
[[UITabBarItem alloc] initWithTitle:#"view3"
image:[UIImage imageNamed:#"view3"]
tag:3];
Try importing QuartzCore, then setting TabBarController.tabBar.layer.zposition = 1. Of course replacing the necessaries like tabBar with the name of your tab bar and so on. This is works in Swift however through your own initiative you can work this into Obj-C

I started using UITabBarController and it is great.
The thing is I have a few views that aren't accessed from the UITabBar
(either presented modal programatically or we want to have a button on the top to jump to them)
The thing is that I want to retain the Tab bar visible in these views.
From my understanding mixing presentViewController and UITabBarController is problematic.
How can I do that? Can I have "hidden" tab bar elements I can reference programatically?
Just to clarify with an example:
Views A,B,C,D are in the tab bar - via the storyboard - everything is peachy.
I NEED to have views E and F clickable from the top navigation (please don't suggest a sliding TabBar or a multiple line UITabBar).
I could just jump to E and F but I want the UITabBar to still be visible so the user can jump from E to A for example.
Just use the good old UINavigationController for every tab and just use [self.navigationController pushViewController:A animated:YES];
That's how the setup looks in code:
SGTabBarViewController *rootVC = [[SGTabBarViewController alloc] init];
SGFirstTabViewController *firstVC = [[SGFirstTabViewController alloc] init];
UINavigationController *navController1 = [[UINavigationController alloc] initWithRootViewController:firstVC];
SGSecondTabViewController *secondVC = [[SGSecondTabViewController alloc] init];
UINavigationController *navController2 = [[UINavigationController alloc] initWithRootViewController:secondVC];
SGThirdTabViewController *thirdVC = [[SGThirdTabViewController alloc] init];
UINavigationController *navController3 = [[UINavigationController alloc] initWithRootViewController:thirdVC];
SGForuthTabViewController *fourhtVC = [[SGForuthTabViewController alloc] init];
UINavigationController *navController4 = [[UINavigationController alloc] initWithRootViewController:fourhtVC];
rootVC.viewControllers = #[navController1, navController2, navController3, navController4];
self.window.rootViewController = rootVC;
[self.window makeKeyAndVisible];
If you want your UITabBar visible on every VC you push just use hidesBottomBarWhenPushed = NO; on it.
However, there is no way to have UITabBar visible on views presented modally.
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];
My IOS app has a login sequence that cannot be modified, once the sequence is complete I do the following in the app delegate
- (UIViewController*)newRootViewController {
NViewController *nView = [[NViewController alloc]
initWithNibName:#"NViewController"
bundle:nil];
UINavigationController *navVC = [[UINavigationController alloc] initWithRootViewController:nView];
[nView release];
return navVC;
}
Once in nView is it possible to add a tab bar controller or how can I replace nView with a tab bar controller.
You can create a UITabBarController then add your NViewController and other controllers to the tab bar.
NViewController *nView = [[NViewController alloc]
initWithNibName:#"NViewController"
bundle:nil];
//Create my tab bar
UITabBarController* myTabController = [[UITabBarController alloc]init];
//Add my tabs
NSArray* tabs = [[NSArray alloc]initWithObjects:nView, nil];
[myTabController setViewControllers:tabs];
I'm just trying a really simple example here as I start to delve into iOS development for ipad.
I'm creating a split view and immediately trying to present a modal form sheet.
Should be really basic.
With what I've tried I get what behaves like a page sheet instead.
In landscape I can see the split view beneath but I don't see the top of my modal view (the tool bar is hidden but is in view in portrait).
I would expect to just grey out the split view beneath a 540x620 modal dialog. I should see the split view beneath my modal in both portrait and landscape like all the nice form sheet dialogs in the Cheddar app for example.
I must be doing something wrong here but all the examples I've read and same within the Cheddar app are doing pretty much what I outline below.
In the app delegate:
MasterViewController *masterViewController = [[MasterViewController alloc] initWithNibName:#"MasterViewController" bundle:nil];
UINavigationController *masterNavigationController = [[UINavigationController alloc] initWithRootViewController:masterViewController];
DetailViewController *detailViewController = [[DetailViewController alloc] initWithNibName:#"DetailViewController" bundle:nil];
UINavigationController *detailNavigationController = [[UINavigationController alloc] initWithRootViewController:detailViewController];
masterViewController.detailViewController = detailViewController;
self.splitViewController = [[UISplitViewController alloc] init];
self.splitViewController.delegate = detailViewController;
self.splitViewController.viewControllers = #[masterNavigationController, detailNavigationController];
self.window.rootViewController = self.splitViewController;
[self.window addSubview:self.splitViewController.view];
ModalViewController *modalView = [[ModalViewController alloc] initWithNibName:#"ModalViewController" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:modalView];
navController.modalPresentationStyle = UIModalPresentationFormSheet;
[self.splitViewController presentViewController:navController animated:NO completion:nil];
The app delegate is way too soon. You have no interface yet, so you can't coherently do any presenting of any view controller.
So, first thing, move all your modalView code to the viewDidAppear: of your detailViewController.
How do you add the Navigation items on the popover (left pane) of the iPad's splitview? This is where the mailboxes/inbox/drafts part of the navigation is in the iPad's builtin email application.
Make the UISplitViewController’s “master” pane a UINavigationController, then just push UIViewControllers on it that have navigationItems.
Here’s a sample setup:
UIViewController *masterController = [[MyCustomMasterController alloc] init…];
[[masterController navigationItem] setTitle:#"Root"];
UINavigationController *navController =
[[UINavigationController alloc] initWithRootController:masterController];
UIViewController *detailController [[MyCustomDetailController alloc] init…];
UISplitViewController *splitView = [[UISplitViewController alloc] init];
[splitView setViewControllers:[NSArray arrayWithObjects:navController,
detailController,
nil]];
And then later on:
UIViewController *subController = [[MyCustomSubController alloc] init…];
[[masterController navigationController] pushViewController:subController
animated:YES];
Pushing a new UIViewController to the UINavigationController’s stack will cause a back button titled “Root” to appear for the MyCustomMasterController view.
