UIView-BooleanAnimations

Perform changes to UI with or without animations, depending on a variable.

Installation

Add the following to your Podfile.

pod 'UIView+BooleanAnimations'

Tun pod install and then use one of the following import statements, depending on if you're using frameworks and ObjC/Swift:

// With Framworks
@import UIView_BooleanAnimations;

// With static libraries
#import <UIView+BooleanAnimations/UIView+BooleanAnimations.h>

// With Swift
import UIView_BooleanAnimations

Use

@interface UIView (BooleanDependantAnimation)
