EEToolbarCenterButton
=============

EEToolbarCenterButton is a component to add a featured button to the center of UIToolbar. It handles button alignment, and helps you use button images whose height is larger than UIToolbar height.

Supported Environment
-----------
iOS 5 or later.

Installation
-----------
EEToolbarCenterButton can be installed by [CocoaPods](http://cocoapods.org/) with your Podfile containing the following line.

pod 'EEToolbarCenterButton'

Or, just copy files in the Classes directory to your project. In this case, you have to add the `-fobjc-arc` compiler flag to the EEToolbarCenterButton source (.m) files if your project doesn't use ARC.

Usage
-----------

The usage of the center button feature is quite similar to that of UIToolbar with UIBarButtonItem. First, import "UIToolbar+EEToolbarCenterButton.h" and turn on the center button feature:

#import "UIToolbar+EEToolbarCenterButton.h"
	
	...
	
	self.toolbar.centerButtonFeatureEnabled = YES;

Then create an EEToolbarCenterButtonItem with custom images and an action selector:

UIImage *centerButtonImage = [UIImage imageNamed:@"ButtonImage"];
    UIImage *centerButtonImageHighlighted = [UIImage imageNamed:@"HighlightedButtonImage"];
    UIImage *centerButtonImageDisabled = [UIImage imageNamed:@"DisabledButtonImage"];
    EEToolbarCenterButtonItem *centerButtonItem = [[EEToolbarCenterButtonItem alloc] 
                                                    initWithImage:centerButtonImage
                                                    highlightedImage:centerButtonImageHighlighted
                                                    disabledImage:centerButtonImageDisabled
                                                    target:self
                                                    action:@selector(didTapCenterButton:)];

At last apply the button to centerButtonOverlay property of UIToolbar added by EEToolbarCenterButton category:

self.toolbar.centerButtonOverlay.buttonItem = centerButtonItem;

Now you find a cool button at the center of UIToolbar. You can enable/disable the center button like a UIBarButtonItem:

centerButtonItem.enabled = NO;

Demo Project
-----------
Open EEToolbarCenterButton.xcodeproj and run.

Customization
-----------

Creating your own button images makes your app unique. The following website lists a number of tutorials to make cool buttons with Photoshop:
