##Usage

###Installation Add the dependency to your Podfile:

platform :ios

pod 'AKTabBarController'

Run pod install to install the dependencies.

Next, import the header file wherever you want to use the tab bar controller:

#import "AKTabBarController.h"

Creation and initialization of the tab bar

// Create and initialize the height of the tab bar to 50px.
_tabBarController = [[AKTabBarController alloc] initWithTabBarHeight:50];

// Create and initialize with specific height and position atop the view controller
_tabBarController = [[AKTabBarController alloc] initWithTabBarHeight:50 position:AKTabBarPositionTop];

// Adding the view controllers to manage.
[_tabBarController setViewControllers:@[[[FirstViewController alloc] init], [[SecondViewController alloc] init], [[ThirdViewController alloc] init], [[FourthViewController alloc] init]]]];  

Setting the title and image

(in each view controller)

// Setting the image of the tab.
- (NSString *)tabImageName
{
	return @"myImage";
}

// Setting the title of the tab.
- (NSString *)tabTitle
{
	return @"Tab";
}

Accessing the current AKTabViewController instance

// Ensure to import AKTabController and the category for UIViewController
#import <AKTabBarController.h>
#import <AKTabBarController/UIViewController+AKTabBarController.h>

// It's now possible to access the current AKTabBarController instance.
- (void)viewDidLoad {
    [super viewDidLoad];

    [self.akTabBarController setTextColor:[UIColor redColor]];
}

Note: self.akTabBarController returns nil on devices running iOS < 5.0.

Customization

Setting the minimum height to display the title

[_tabBarController setMinimumHeightToDisplayTitle:50];

Hide the tab title

[_tabBarController setTabTitleIsHidden:NO];

Hide the tab bar when pushed in an UINavigationController

When pushing a viewcontroller in the viewControllers stack of an UINavigationController it is possible to hide the tab bar. It works exactely like the original UITabBarController:

[viewController setHidesBottomBarWhenPushed:YES];
