mnfloatingactionbutton's Introduction

MNFloatingActionButton

A little iOS experiment, a Floating Action Button.

Installation

As Cocoapod https://cocoapods.org

pod 'MNFloatingActionButton', '~> 2,0'

Alternatively, add the images and .h &.m files to your project.

General Usage

Just like a normal button, you instantiate with a frame and add as a subview.

MNFloatingActionButton *button = [[MNFloatingActionButton alloc] initWithFrame:CGRectMake(0,0,50,50)];
[self.view addSubview:button];

As it is a subclass of UIControl, you can add a target to listen to touch events. The touch events that are sent are:

UIControlEventTouchUpInside
UIControlEventTouchCancel

[button addTarget:self action:@selector(createButtonPressed:) forControlEvents:UIControlEventTouchUpInside];

You can also use MNFloatingActionButton in Storyboards and xibs by creating a UIView object and changing it's custom class to MNFloatingActionButton.

Customisation

There are currently 6 properties that you can modify to customise your button. They are:

centerImage - Set to nil if you don't want an image
backgroundColor - Defaults to some kinda blue
shadowColor - Defaults to the background color.
shadowOpacity - Default is 0.6f
shadowRadius - Default is 1.5f
animationScale - Set's the end size of button when pressed. Defaults to 0.85f
animationDuration - Defaults to 0.05f

Thanks

I did this because I thought it might be fun for people to play around with. If you like, or you don't like it, then help make it better with a PR!

mnfloatingactionbutton's Issues

Wrong image position

Hi, I'm adding your button from code using autolayot, and when button appears, "+" image placed outside of button. Here is my code sample:

    _menuButton = [[MNFloatingActionButton alloc] initWithFrame:CGRectMake(0, 0, 50, 50)];

    [self.view addSubview:_menuButton];
    _menuButton.translatesAutoresizingMaskIntoConstraints = NO;
    NSDictionary *views = NSDictionaryOfVariableBindings(_menuButton);

    [self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:[_menuButton(50)]-20-|"
                                                                                               options:0
                                                                                               metrics:nil
                                                                                                 views:views]];
    [self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:[_menuButton(50)]-20-|"
                                                                                               options:0
                                                                                               metrics:nil
                                                                                                 views:views]];

After pressing button, "+" image appears on right place

needs example project

Allow image to be configurable

Would it be possible to give us a Setter for the image? I'm kinda just hacking it in there by deleting the subview and re-adding in an image right now :)
