BATabBarController

Overview

The standard TabBarController is very limited in terms of animations when you make a selection. This cocoapod allows you to use one with a sleek animation with customizable properties!

Requirements

• iOS 8+ iPhone, iPad and iPod Touch devices

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Getting Started

Installation

BATabBarController is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "BATabBarController"

Usage

Default with No Text in Tab Bar

The example below create the default BATabBarController tab bar (default properties) without text.

UIViewController *vc1 = [[UIViewController alloc] init];
UIViewController *vc2 = [[UIViewController alloc] init];
UIViewController *vc3 = [[UIViewController alloc] init];

BATabBarItem *tabBarItem = [[BATabBarItem alloc] initWithImage:[UIImage imageNamed:@"icon1_unselected"]      
                                                 selectedImage:[UIImage imageNamed:@"icon1_selected"]];
BATabBarItem *tabBarItem2 = [[BATabBarItem alloc] initWithImage:[UIImage imageNamed:@"icon2_unselected"]      
                                                  selectedImage:[UIImage imageNamed:@"icon2_selected"]];
BATabBarItem *tabBarItem3 = [[BATabBarItem alloc] initWithImage:[UIImage imageNamed:@"icon3_unselected"]      
                                                  selectedImage:[UIImage imageNamed:@"icon1_selected"]];

BATabBarController *baTabBarController = [[BATabBarController alloc] init];
baTabBarController.viewControllers = @[vc1,vc2,vc3];
baTabBarController.tabBarItems = @[tabBarItem,tabBarItem2,tabBarItem3];                                                        baTabBarController.delegate = self;
[self.view addSubview:baTabBarController.view];

This creates the following:

Default with Text in Tab Bar

The example below create the default BATabBarController tab bar (default properties) with text.

UIViewController *vc1 = [[UIViewController alloc] init];
UIViewController *vc2 = [[UIViewController alloc] init];
UIViewController *vc3 = [[UIViewController alloc] init];

NSMutableAttributedString *option1 = [[NSMutableAttributedString alloc] initWithString:@"Option1"];
[option1 addAttribute:NSForegroundColorAttributeName value:[UIColor colorWithHex:0xF0F2F6] range:NSMakeRange(0,option1.length)];
BATabBarItem *tabBarItem = [[BATabBarItem alloc] initWithImage:[UIImage imageNamed:@"icon1_unselected"]    
                                                 selectedImage:[UIImage imageNamed:@"icon1_selected"]
                                                         title:option1];

NSMutableAttributedString *option2 = [[NSMutableAttributedString alloc] initWithString:@"Option2"];
[option2 addAttribute:NSForegroundColorAttributeName value:[UIColor colorWithHex:0xF0F2F6] range:NSMakeRange(0,option2.length)];
BATabBarItem *tabBarItem2 = [[BATabBarItem alloc] initWithImage:[UIImage imageNamed:@"icon2_unselected"]
                                                  selectedImage:[UIImage imageNamed:@"icon2_selected"]
                                                          title:option2];

NSMutableAttributedString * option3 = [[NSMutableAttributedString alloc] initWithString:@"Option3"];
[option3 addAttribute:NSForegroundColorAttributeName value:[UIColor colorWithHex:0xF0F2F6] range:NSMakeRange(0,option3.length)];
BATabBarItem *tabBarItem3 = [[BATabBarItem alloc] initWithImage:[UIImage imageNamed:@"icon3_unselected"]
                                                  selectedImage:[UIImage imageNamed:@"icon3_selected"]
                                                          title:option3];

BATabBarController *baTabBarController = [[BATabBarController alloc] init];
baTabBarController.viewControllers = @[vc1,vc2,vc3];
baTabBarController.tabBarItems = @[tabBarItem,tabBarItem2,tabBarItem3];                                                        baTabBarController.delegate = self;
[self.view addSubview:baTabBarController.view];

This creates the following:

##Methods ###Set Selected View Controller You can change the currently selected tab bar item programatically by using the method below. To avoid the animation pass false in the second parameter: setSelectedViewController:(UIViewController*)viewController animated:(BOOL)animated

BATabBarControllerDelegate

If you'd like to add external actions when a tab item is selected, you can use: tabBarController:(BATabBarController *)tabBarControllerdidSelectViewController:(UIViewController *)viewController

Properties

Tab Bar Color

To change the color of the tab bar, you can change the tabBarBackgroundColor property of the BATabBarController instance.

baTabBarController.tabBarBackgroundColor = [UIColor blackColor];

result:

Tab Bar Item Stroke Color

baTabBarController.tabBarItemStrokeColor = [UIColor blueColor];

result:

Tab Bar Item Line Width

To change the size of the stroke in the animation, you can change the tabBarItemLineWidth property of the BATabBarController instance.

baTabBarController.tabBarItemLineWidth = 1.0;

result:
