How To Get Started

Use Pod (or download and add "UIImageViewModeScaleAspect.swift" in your xcodeprojet.) :

pod 'UIImageViewModeScaleAspect'

Init the UIImageViewModeScaleAspect. Important ! Do not forget to init the contentMode :

``` swift let myImage = UIImageViewModeScaleAspect(frame: CGRect(x: 0, y: 100, width: 200, height: 100)) myImage.contentMode = .scaleAspectFill // Add the first contentMode myImage.image = UIImage(named: "Octocat") view.addSubview(myImage) ```

Automatic animation

For convert UIViewContentModeScaleAspectFill to UIViewContentModeScaleAspectFit :

``` swift myImage.animate( .fit, frame: CGRect(x: 0, y: 0, width: 200, height: 200), duration: 0.4) ```

For convert UIViewContentModeScaleAspectFit to UIViewContentModeScaleAspectFill :

``` swift myImage.animate( .fill, frame: CGRect(x: 0, y: 0, width: 200, height: 200), duration: 0.4) ```

Manual animation

For convert UIViewContentModeScaleAspectFill to UIViewContentModeScaleAspectFit :

``` swift myImage.initialeState(.fit, newFrame: CGRect(x: 0, y: 100, width: 200, height: 100))

UIView.animate(withDuration: 0,4, delay: 0, options: .allowAnimatedContent, animations: { // // Others Animation // myImage.transitionState(.fit) }, completion: { (finished) in myImage.endState(.fit) })

<p>For convert UIViewContentModeScaleAspectFit to UIViewContentModeScaleAspectFill :</p>
``` swift
myImage.initialeState(.fill, newFrame: CGRect(x: 0, y: 100, width: 200, height: 100))

UIView.animate(withDuration: 0,4, delay: 0, options: .allowAnimatedContent, animations: {
  //
  // Others Animation
  //
  myImage.transitionState(.fill)
}, completion: { (finished) in
  myImage.endState(.fill)
})
