Ussage

Don't forget to check out an example project.

Copy files

You need to copy the following files to your project:

• DOTabbar.h
• DOTabbar.m
• DOTabbarItemCell.h
• DOTabbarItemCell.m

Make sure to add them to the target.

Use in project

You can use DOTabbar in Inteface Builder: just drag a Custom View into your window and set it class to DOTabbar. After that you need to set a delegate to your tab bar and implement it.

Your delegate must adopt DOTabbarDelegate protocol:

@protocol DOTabbarDelegate <NSObject>
	// Your groups identifiers
	- (NSArray *)tabbarGroupIdentifiers:(DOTabbar *)tabbar;
		
	// Item identifiers for each group
	- (NSArray *)tabbar:(DOTabbar *)tabbar itemIdentifiersForGroupIdentifier:(NSString *)identifier;
		
	// Cell for each item 
	- (NSCell *)tabbar:(DOTabbar *)tabbar cellForItemIdentifier:(NSString *)itemIdentifier;
		
	@optional
		
	// Title for group. Can be empty
	- (NSString *)tabbar:(DOTabbar *)tabbar titleForGroupIdentifier:(NSString *)identifier;
		
	// Informs delegate that new item was selected
	- (void)tabbar:(DOTabbar *)tabbar didSelectItemWithIdentifier:(NSString *)identifier;
@end

Customizing

For customizing tab bar you can create your custom NSCell subclass and return it in your delegate tabbar:cellForItemIdentifier: method.

DOTabbar uses ARC.
