I was playing around with BCTabBarController I I noticed the tabbar is not hidden when I present another viewcontroller modally. The standard behaviour of UITabBarController seems to be that the TabBar is hidden.

Is this a known issue? I don't know if it's related to the hidesBottomBarWhenPushed issue?

ViewWillAppear, ViewDidAppear, ViewWillDisappear ViewDidDisappear methods not called in selectded view controller and not called into BCTabBarController.
This problem appears after BCTabBarController show modal controller from instance of BCTabBarController class.

I Wanna Remove A BCTabBarController when press To Button In One Of It's Child ?

I switched out the standard UITabBarController with your's and I just get a blank screen. I'm starting to dig through the code but wondering if you have seen this before. For some reason in the "loadView" method I get null for the applicationFrame:

NSLog(@"[[UIScreen mainScreen] applicationFrame] = %@", [[UIScreen mainScreen] applicationFrame]);
// prints null
NSLog(@"[[UIScreen mainScreen] applicationFrame].size.width = %d", [[UIScreen mainScreen] applicationFrame].size.width);
// prints 0

I managed to resolve this with a

[selectedViewController release];

at line 34 of BCTabBarController.

Either we provide a way to replace them with landscap-y icons or just shrink them programmatically if no -landscape.png file is found.

see screenshot: https://skitch.com/steipetee/r8cqk/ios-simulator

I've done all steps in Usage section except the second step, because I did not see any box to be checked.
As written in http://www.section42.de/2011/04/12/bctabbarcontroller-and-xcode-4/ , I should see the entry “libBCTabBarController.a” in the left pane of XCode.
But now I can't find the entry “libBCTabBarController.a” in there.

As the result, I can't do
#import "BCTabBarController.h"
in my delegate.m file. There is lexical or preprocessor issue, 'BCTabBarController.h' file not found.
But I can do
@Class BCTabBarController;
from my delegate.h file

Did I miss something?

Usage

Add BCTabBarController.xcodeproj to your project by dragging it into the Groups & Files sidebar.
Select the added project file in the sidebar and then check the box next to libBCTabBarController.a
Select your project's target and right-click and choose "Get Info"
Click the + icon underneath Direct Dependencies and add the BCTabBarController target
libBCTabBarController.a should already be in the list of Linked Libraries
Drag BCTabBarController.bundle into your project's resources
If you haven't already, add the QuartzCore and Core Graphics frameworks to your project
Define the method - (NSString *)iconImageName in each view controller that you add to the tab bar. It should return the filename of the grey tab icon (see creation steps below)
See the example target for usage

Is it planned to support iPads?

On the iPad 2 with iOS 5.0.1 are several issues.

• The white line is still there in landscape and portrait mode
• landscape: tabbar only shows a subset of icons (the rest of the bar is black, but icons can be tapped and then show up)
• landscape: the tabbar is placed too low
• some more

At first I suspected it was the way my application was setup, but I created a test application using the EXViewController and generated the BCTabBarController in my app delegate, and I get viewWillAppear and viewDidAppear triggered twice.

Any thoughts?

Hi,

When I try to add a title to the tab bar, it is formatted incorrectly. The text cannot fit and its to the side, I want it to be below the icon

I'm using this component and I have a black box between the tabbar (correctly set on the bottom) and the content view....
Is it a known pb ?

Tx for the support.

-Fred

I tried implementing the tab bar in my project, which contains Nav controllers with UIViewControllers just like the example, however the icons don't appear. If I try with just the UIViewController it works. In my project I try to recreate the example, and I even use the EXViewController class. The issue could be that I started the project as a Windows Based Application? That's the only difference I can discern.

Please refer the attached screen shot.

This would make the controller a more suitable drop-in replacement for UITabBarController.

Hi there,

thanks for the great tabbar controller! Would it be possible to add something like the popup item feature of Tweetbot to it? Like when you press a tabbar item it pops up more items?

If this isn't something you want to do, can you point me in the right direction how to best do it?

Thanks again,
Shukuyen.

Hi,

Thanks in Advance :)

Take a look at what Peter Boctor does in his custom implementation, there you can find code how to do the blue overlay programatically, would be a huge improvement.

Hi,

I am getting following error where I am archiving for distribution only.
Its working fine on simulator and even on device with Developer Profile.

If one tab bar uses navigationController, the self.hidesBottomBarWhenPushed is invalid when I push a new view controller.
In fact I need to hide the tab bar when I push a new view controller.

You can try this： CYLTabBarController .

I'm trying to implement the tab bar but some, not all, of the icons I make come out blurry. I though it was just me. I don't know what is causing it. I'm using the same icon for all my tab bar items just as a test. So, it's the same image but blurry in different tab bar items.
