SingleLineShakeAnimation

TLDR; Shake a view with a single line of code with a non-intrusive extension for UIView, with good support for accessability, written in Swift.

With this non-intrusive UIView extension, your UIView subclasses can get shaking with very little code. Shaking can be useful to indicate an important action your user needs to perform, for example filling out a form before submitting. Show the user it by gently shaking the needed view to get their attention.

Installation

pod "SingleLineShakeAnimation"

Usage

import library

import SingleLineShakeAnimation

Basic horizontal shake

button.shake(.Horizontal)

Basic vertical shake

button.shake(.Vertical)

Using the default values, 5 times back and forth, animating for 0.5 seconds.

Basic vertical shake with accessability

usernameTextField.shake(.Vertical)?.postAccessabilityNotification(text:"You need to write a username before tapping login button")

Checks if VoiceOver is activated, if it is, it reads the text instead of shaking.

Example

Customized usage

Vertical shake with completion block.

button.shake(.Vertical, completion: { 
            // do something after animation finishes
        })

Stating number of times to go back and forth and total duration for the whole animation to take.

button.shake(.Horizontal, numberOfTimes: 10, totalDuration: 0.6, completion: {
            // do something after animation finishes
        })

• Easing on animation

Single Line APIs

Really good APIs should not need more than a single line of code to work and be as non intrusive as possible. This library is a part of my ongoing effort to build single line libraries for iOS. Check out the other ones on the list as well.
