Overview

Multiple State Toggle UIButton

A UIButton subclass that implements tap-to-toggle button text. (Like the camera flash and timer buttons)

Usage

Just create it with the states, and it's good to go:

let toggleButton = MultiToggleButton(image: myImage, states: ["First", "Second", "Last"])

Get and set the current state:

let state = toggleButton.currentStateIndex
toggleButton.currentStateIndex = 0

Add a tap action (in addition to the built-in state toggle):

toggleButton.action = { (sender) -> () in
    doStuff(sender.currentStateIndex)
}

Set different colors for different states (nil uses the button's tintColor):

toggleButton.colors = [nil, .gray, .red]

Set different images for different states:

toggleButton.images = [myFirstImage, mySecondImage, myLastImage]

Or do it all at once:

let toggleButton = ToggleButton(
    images: [myFirstImage, mySecondImage, myLastImage],
    states: ["First", "Second", "Last"],
    colors: [nil, .gray, .red],
    action: { (sender) -> () in doStuff(sender.currentStateIndex) }
)

Add storyboard compatibility, declare class public

Storyboards use init(decoder) to initialize their content, so they avoid your convenience inits. This leads setting an action to the button to be useless because the target-action isn't set. I've changed action property setter to solve this. Calling addTarget() multiple times without removeTarget() shouldn't be a problem, because all targets are stored in a dictionary (so setting new value basically overrides old).

class isn't visible and CocoaPods issue
Hi! There are two issues:

Swift code doesn't see the class when importing the module (because the class isn't declared as public).

I've added your code using CocoaPods and it turned out that the pod is outdated

Can handle a different image for each state

image → [images]

Also, polishes the demo project a bit (I love SwiftGen), and accepts Xcode's suggested changes, whatever they happened to be.

Awesome project, תודה רבה!
