Is there any way to change title on "More" tab (text on uitabbaritem)?
well..If you want to change the title of the navigation bar of your more tab use the method given by 7KV7
and if you want to change the tab title ...
there is an another way..
suppose you have eight tabs..
1) In your tab Bar controller ...make only five tabs...remove all the other views other than five tabs..
2)lets make your fifth tab as your "more tab"...take it as a tableviewController and in it's tableView elements add elements as your sixth..seventh..eighth tab's name and image...
3)in fifthViewController's rowdidselect method navigate the sixth , seventh and eighth tab's respective view controllers..
Pros:-you can change the name and the image of the more tab
Cons:-well you can not use the edit button of your more tab where you can change the tab element's order..
try it if you are comfortable with this..

Yes, it is possible.
UINavigationBar *moreNavigationBar = tabBarController.moreNavigationController.navigationBar;
moreNavigationBar.topItem.title = #"Your title";
tabBarController is your UITabBarController
In your UITabBarController you just add this simple line under the viewDidLoad and under superViewDidLoad:
self.moreNavigationController.navigationBar.topItem.title = #"Your Title";
So then it should look like this:
- (void)viewDidLoad {
[super viewDidLoad]; // Do any additional setup after loading the view.
self.moreNavigationController.navigationBar.topItem.title = #"Mer";
}
To make it worked I also created a new Objective-c class naming it: "MyTabBarController". And then I clicked my TabBarController in storyboard and set the class to: "MyTabBarController". When I pasted the code in the .m file it worked perfectly.

I use in my application, the side bar menu like in facebook, so I have different cells in this menu, what I want is to when click on a cell push me to another view controller. I face a problem here which is: the menu is a table view which I don't have it in storyboard, I use some classes from this site:github
and I've stucked here, in my application I use a storyboard, but this menu is programmed with code, and doesn't have a view in stroyboard,
in the didSelectRowAtIndexPath method: I use like this
for(int j=0; j< 9 ; j++)
{
if(indexPath.row == j)
{
DetailsSidebarViewController *essayView = [[DetailsSidebarViewController alloc] init];
essayView.detailItem = [jsonResults objectAtIndex:j];
NSLog(#"%#=%d",essayView.detailItem,j);
}
}
and I create a DetailsSidebarViewController as the new view controller when I push from menu item. in this class, I create a method to configure the view, and just I echo the result:
- (void)configureView
{
// Update the user interface for the detail item.
if (self.detailItem) {
NSLog(#" %# ", self.detailItem);
}
}
the result is true like I want, but I want to push to another view controller, in fact nothing is happened when I click on an item into the menu.
How can I create the new view controller in storyboard? if the menu has not a storyboard, and how can I connect them with segues?
In fact, I am blue with it, please help!!
You should make an instance of the App Delegate class in the Side Menu view controller, and push it from there. You must have a reference to the Side Menu View and a reference to the Center View! Import your App Delegate into the Side Menu controller, and in the didSelectRowAtIndexPath, use:
DetailsSidebarViewController *essayView = [[DetailsSidebarViewController alloc] init];
essayView.detailItem = [jsonResults objectAtIndex:indexPath.row]; // note that you don't need the for loop to know what object you need
AppDelegate* myAppDelegate = (AppDelegate*)[[UIApplication sharedApplication] delegate];
[myAppDelegate.sideMenuViewController toggleSideMenu]; // the idea here is that you have to close the side menu, i.e. it must dissapear
[myAppDelegate.centerViewController.navigationController pushViewController:essayView animated:YES];
This is all the code you need.
If I may, as a piece of advice, use Mike Frederik's MFSideMenu instead of the library you're using. In my opinion, it has a more simple and a more straightforward implementation, just look into the README file, everything is explained pretty simple, and it has exactly the code you need!
Hope this helps, good luck!
I have a TabBarController with two tabs; first is InputViewController and second one is TableviewController.
Input view controller has two text fields when I enter the text, after that I want to receive that text filed value in to TableviewController (in the next tab). It does not receive the value.
Try to use this concept.....
Declare two variables in Second tab that is Tableviewcotroller..
For exa..
NSString *strname;
NSString *straddr;
#property and #synthesize both...
Now, in your *InputViewCotroller*tab, create and initialize object of TableViewcotroller, using this object, access these varibles. Like, you want to get values of textfields.
Tableviewcotroller *objTable = ........
objTable.strname = self.textName.text;
objTable.straddr = self.txtAddr.text;
Implement this concept in your project...Hope this helps you...:)
What ever value you have in input view controller like
NSString*text1=textbox1.text;
NSString*text2=textbox2.tex;
In the method where you are moving to next view you should pass the value to the table view controller like this
DetailViewController*tblViewController=[[DetailViewController alloc]init];
NSString*textValue1=text1;
tblViewController.textValue1=textValue;
[self.navigationController pushViewController:tblViewController];
you should alos have textValue NSString in tableView controller also to assign value
I created a tabBar app in Interface Builder - and named all my tabs and tab-items there. Can I now programmatically find out or retrieve the names of my tabs during run-time?
When I do an NSLog of the viewControllers array, all I get is:
(
"",
"",
"",
"",
""
)
That's obviously no good - I need to get more specific info.
Also, I noticed you can't set a tag, title or label in IB to any of the view-controllers in your tabs.
So how can you identify through code what you have sitting in your various tabs? Or do you have to ditch Interface Builder and do everything by code?
for(id btn in TabObject.tabBar.items)
{
if([btn isKindOfClass:[UITabBarItem class]])
{
UITabBarItem *sender=btn;
NSLog(#"%#",sender.title);
}
}
The tab bar item within each view controller contains the title.
for (UIViewController *viewController in tabBarController.viewControllers) {
NSLog(#"%#", viewController.tabBarItem.title);
}
Having said that, I think the best way to refer to specific tabs is to have explicit IBOutlets from the app delegate to each view controller. Since there's not going to be more than a handful, this shouldn't be too much extra code.
I am adding a badge to my UITabBarController's UITabBar as such:
UITabBarItem *tbi = (UITabBarItem *)[stTabBarController.tabBar.items objectAtIndex:1];
tbi.badgeValue = #"2";
However, my UITabBarController is customizeable, so the index may change. How can I make sure the badge gets applied to the correct UITabBarItem?
One suggestion you might consider is setting a tag on each tab bar item. You can do this in Interface Builder or when you create the item by code. You can then loop through the view controllers in the tab bar controller looking for the one with the tab bar item you are interested in. For example:
// #define MyTabBarItemTag 999
for (UIViewController *viewController in stTabBarController.viewControllers) {
if (viewController.tabBarItem.tag == MyTabBarItemTag) {
viewController.tabBarItem.badgeValue = #"2";
}
}
UITabBarItem *tbi = (UITabBarItem *)self.tabController.selectedViewController.tabBarItem;
tbi.badgeValue = #"New";
Also works.
Swift version:
self.tabBarController?.selectedViewController?.tabBarItem.badgeValue="12";
I'd use an NSMutableDictionary property on the class that owns the tab bar controller, associating tab names with positions, and a method to retrieve by name:
-(UITabBarItem*)getTabByName:(NSString*)tabName {
return [stTabBarController.tabBar.items objectAtIndex:[[tabDict valueForKey:tabName] intValue]];
}
Initialize the dictionary in your setup code for each tab, since you know the tab index at that time:
[tabDict setValue:[stTabBarController.tabBar.items objectAtIndex:1] forKey:#"myTabName"];
Keep a reference to the tab bar item that you want to modify.
EDIT as a response to your code request:
I believe that there is a single place in your app where you update the badges on the tab bar items. Just add an array of tab bar items (or separate tab bar items) as a member(s) of that class (+ properties if needed) and update the items directly without fetching from the current tab bar items list ((UITabBarItem *)[stTabBarController.tabBar.items objectAtIndex:1];).
For instance, if you decide to keep references to the tab bar items directly (without an array) then the code might look like that:
// Put the next code right after initiating the tab bar and/or after adding new tab bar items to it...
self.newsTabBarItem = (UITabBarItem *)[stTabBarController.tabBar.items objectAtIndex:1];
self.friendsTabBarItem = (UITabBarItem *)[stTabBarController.tabBar.items objectAtIndex:2];
// etc.
Okay, here is my issue: My app has a display of categories in the tab bar at the bottom of the iPhoneOS screen. This only allows 5 categories before it presents the MORE button. I have over 25 (please do not answer this by saying: "Rethink your application...etc" -- that was rudely said before. They are food, drink, etc categories and cannot be changed). I want to allow the user to put their favorites on the home page. The Apple moreNavigationController editing system only allows 20 tab bar items to be rearranged due to space constraints on the editing page. This is not enough so i need to implement my own Editing screen. I set the rightBarButtonItem to nil and created my own. Using NSLog, i can see the "click" happens when clicking the EDIT button, but I cannot push using pushViewController. Nothing happens. I think it has something to do with the navigationController I am addressing...but i am not sure. ps: This all happens in my App Delegate which DOES act as both UITabBarControllerDelegate & UINavigationControllerDelegate.
I tried to do the following:
- ( void )navigationController:( UINavigationController * )navigationController_local willShowViewController:( UIViewController * )viewController_local animated:( BOOL )animated
{
UIViewController * currentController = navigationController_local.visibleViewController;
UIViewController * nextController = viewController_local;
// Do whatever here.
NSLog(#"Nav contoller willShowViewController fired\n'%#'\n'%#'\nThere are currently: %d views on the stack\n",currentController,nextController,[self.navigationController.viewControllers count]);
if ( [nextController isKindOfClass:NSClassFromString(#"UIMoreListController")])
{
UINavigationBar *morenavbar = navigationController_local.navigationBar;
UINavigationItem *morenavitem = morenavbar.topItem;
morenavitem.rightBarButtonItem = nil;
NSLog(#"Is a UIMoreListController\n");
UIBarButtonItem *editTabBarButton = [[UIBarButtonItem alloc]
initWithTitle:#"Edit"
style:UIBarButtonItemStylePlain
target:self
action:#selector(editTabBar:)];
morenavitem.rightBarButtonItem = editTabBarButton;
[editTabBarButton release];
}
}
This works to place an EDIT button at the top right of the screen -- mimicking Apple's look and feel... but when that button is clicked, you cannot exit the darn moreNavigationController.
I have tried many things. UIAlerts work, etc...but pushing (or popping -- even popping to root view) a view controller on the stack does not.
- (void) editTabBar:(id)sender {
NSLog(#"clicked edit tabbar\n");
NSLog(#"Total count of controllers: %d\n",[self.navigationController.viewControllers count]);
TabBarViewController *tabBarViewController2 = [[TabBarViewController alloc] initWithNibName:#"TabBarView" bundle:nil];
tabBarViewController2.navigationItem.title=#"Edit Tab Bar";
[self.navigationController pushViewController:tabBarViewController2 animated:YES];
[tabBarViewController2 release];
NSLog(#"finished edit tabbar\n");
}
If you click the edit button on the moreNavigationController's display page, you get the log entries like expected AND (this is strange) the views on the stack climbs -- but no page change occurs. I marked it down to not using the correct navigation controller...but I am lost on how to find which one TO use.
this is a weird one too. In the edit function if i just do this:
- (void) editTabBar:(id)sender {
self.tabBarController.selectedIndex = 0;
}
It DOES take me home (to tabbarcontroller 0)
BUT doing this:
- (void) editTabBar:(id)sender {
[self.navigationController popToRootViewControllerAnimated:YES];
}
does not work.
Does the moreNavigationController have some special quality that screws with the rest of the system?
I would try reimplementing the whole "More" functionality from scratch. In other words, store the four home tabs in your user defaults and add a dummy fifth tab that switches to your own complete reimplementation of the more view controller stack.
You could even write a lightweight subclass of UITabBarController that handled this for you.
UITabBarController is evil, so I wouldn't be at all surprised if MoreController had some special properties, too.
I have had success intercepting the More Controller in shouldSelectViewController to change the data source; you may be able to find some workaround there.
PS I am inclined to agree that you could consider redesigning your app so that you didn't need an unlimited number of viewControllers attached to the tab bar just to select categories; you might have better luck using a tool bar with a single, scrollable, custom view in it. If that's really the best way of picking categories for your app, of course.
