Welcome to Motion

Motion is a tool used to create transition animations between view controllers.

Sample

Take a look at a sample Photo Collection project.

Motion Photo Collection Sample

Features

  • [x] Add animations to views and layers.
  • [x] Setup custom transition animations between view controllers.

Requirements

  • iOS 8.0+
  • Xcode 8.0+

Communication

  • If you need help, use Stack Overflow. (Tag 'cosmicmind')
  • If you'd like to ask a general question, use Stack Overflow.
  • If you found a bug, and can provide steps to reliably reproduce it, open an issue.
  • If you have a feature request, open an issue.
  • If you want to contribute, submit a pull request.

Installation

Embedded frameworks require a minimum deployment target of iOS 8.
- Download Motion

Visit the Installation page to learn how to install Motion using CocoaPods and Carthage.

Changelog

Motion is a growing project and will encounter changes throughout its development. It is recommended that the Changelog be reviewed prior to updating versions.

Motion Animations

You can add animations to any UIView or CALayer using the motion API with an optional completion block. For example, to change the background color of a view with a 45 degree rotation:

view.motion([.backgroundColor(.blue), .rotationAngle(45)]) {
    // Do something when complete.
}

Available Motion Animation Values

  • delay
  • timingFunction
  • duration
  • custom
  • backgroundColor
  • barTintColor
  • cornerRadius
  • transform
  • rotationAngle
  • rotationAngleX
  • rotationAngleY
  • rotationAngleZ
  • spin
  • spinX
  • spinY
  • spinZ
  • scale
  • scaleX
  • scaleY
  • scaleZ
  • translate
  • translateX
  • translateY
  • translateZ
  • x
  • y
  • point
  • position
  • fade
  • zPosition
  • width
  • height
  • size
  • shadowPath
  • shadowOffset
  • shadowOpacity
  • shadowRadius
  • depth

Motion Transitions

Motion allows for view controllers to animate between each other. By adding a value to a view's motionIdentifier property, a view will animate to the look of another view. For example, animating a floating button to a bar:

Motion Button To Bar

From View Controller

button.motionIdentifier = "options"

To View Controller

bar.motionIdentifier = "options"

That's it. By setting the motionIdentifier property, Motion animates one view to another within different view controllers.

Motion Transition Animations

View animations may be added to views that are transitioning using the motionAnimations property.

bar.motionAnimations = [.delay(0.35), .duration(3)]

Enabling Motion Transitions

To turn on Motion transitions between view controllers, set the isMotionEnabled property to true within the view controllers that transition between each other, and any container controllers, such as UINavigationController.

Motion Delegate

Use the MotionDelegate to tap into key parts of a transition between view controllers. The available delegation methods are:

func motion(motion: Motion, willTransition fromView: UIView, toView: UIView)

func motion(motion: Motion, didTransition fromView: UIView, toView: UIView)

func motionDelayTransitionByTimeInterval(motion: Motion) -> TimeInterval
