Overview

LBHamburgerButton is an iOS control that displays 3 lines (hamburger) and other icon (back, close...) without using image. It has a beautiful, clean and smooth transition between 2 state like Google Material Design or "close button" of Paper app.

Requirement

LBHamburgerButton use QuartzCore framework, so dont forget to add this framework. ARC (iOS 5+) is also required.

How to use

First, you need to copy 2 files LBHamburgerButton.h/.m to your project. Then, import them to your class

#import "LBHamburgerButton.h"

This is a sub-class of UIButton. So you can init a simple button and call set-up method:

buttonHamburger = [[LBHamburgerButton alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
[buttonHamburger setUpHamburgerWithType:LBHamburgerButtonTypeCloseButton
                              lineWidth:50
                             lineHeight:50/6
                            lineSpacing:5
                             lineCenter:CGPointMake(50, 50)
                                  color:[UIColor whiteColor]];

var hamburgerButton = LBHamburgerButton(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
hamburgerButton.setUpHamburger(type: LBHamburgerButtonType.closeButton, lineWidth: 50, lineHeight: 50/6, lineSpacing: 5, lineCenter: CGPoint(x: 50, y: 50), color: UIColor.white)

or use full contructor like this:

buttonHamburger = [[LBHamburgerButton alloc] initWithFrame:CGRectMake(0, 0, 100, 100)
                                         withHamburgerType:LBHamburgerButtonTypeCloseButton
                                                 lineWidth:50
                                                lineHeight:50/6
                                               lineSpacing:5
                                                lineCenter:CGPointMake(50, 50)
                                                     color:[UIColor whiteColor]];

var hamburgerButton = LBHamburgerButton(frame: CGRect(x: 0, y: 0, width: 100, height: 100), type: LBHamburgerButtonType.closeButton, lineWidth: 50, lineHeight: 50/6, lineSpacing: 5, lineCenter: CGPoint(x: 50, y: 50), color: UIColor.white)

Set other propertises, add target add it to view like UIButton.

[buttonHamburger setCenter:CGPointMake(120, 120)];
[buttonHamburger setBackgroundColor:[UIColor blackColor]];
[buttonHamburger addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];

[self.view addSubview:buttonHamburger];

hamburgerButton.center = CGPoint(x: 120, y: 120)
hamburgerButton.backgroundColor = UIColor.black
hamburgerButton.addTarget(self, action: #selector(LBViewController.buttonPressed(_:)), forControlEvents: UIControlEvents.touchUpInside)

self.view.addSubview(hamburgerButton)

When you want to switch state, just call switchState.

- (void)buttonPressed:(id)sender {
    LBHamburgerButton* btn = (LBHamburgerButton*)sender;
    [btn switchState];
}

@objc func buttonPressed(sender: UIButton) {
  var btn = sender as LBHamburgerButton
  btn.switchState()
}
