This control provides an alternative to animating an array of images with an UIImageView. Only a single image composed of individual sprite frames is used, and animation simply consists of updating the layer contentsRect.

Create a sprite sheet asset

A sprite sheet consists of a single image composed of a single column of individual sprite frames. The individual sprite frames must be sized and spaced evenly across the overall image bounds. A typical use case is to generate three sprite sheet images (1x, 2x, and 3x) and add these to an .xcassets file for use in the app by the spritedAnimationView.

Animating the sprite sheet

Once a sprite sheet is added to a spritedAnimationView (either at init or adding later), the spritedAnimationView can animate the image from the first sprite frame to the last sprite frame. Properties are available to set the frame rate, which defaults to 60 fps (frames per second). The animation can happen once or be looped via the animationRepeatCount property. To start the animation, use the -startAnimationWithCompletion: method. A completion block gets called once the animation is finished. However, if the animationRepeatCount is set to loop infinitely (with a 0 setting), this block will not get called. Additional methods are provided to reset the spritedAnimationView to the beginning or end without animation.

Achieving two-state animation

It is enough to provide a single sprite sheet, animate the image, and simply reset to the beginning once finished. However, in some cases, a nice user experience can be achieved by providing two separate sprite sheets. One showing an animation from state A to state B, then another sprite sheet showing state B going back to state A. This way, the sprite sheet can be swapped out after the animation completes for each state, and be replaced with the other sprite image.

Two sample sprite sheets (showing List and Grid icon states)

List Sprite Sheet Grid Sprite Sheet
List Icon Grid Icon

Two-state example

// Animate the sprited view.
[_animationView startAnimatingWithCompletion:^(BOOL finished) {

  // When animation completes, toggle image.
  _toggle = !_toggle;
  UIImage *spriteImage =
      [UIImage imageNamed:_toggle ? kSpriteGridImage : kSpriteListImage];
  _animationView.spriteSheetImage = spriteImage;



Before using Sprited Animation View, you'll need to import it:


#import "MaterialSpritedAnimationView.h"


import MaterialComponents

Integrating the spritedAnimationView is somewhat similar to adding an UIImageView to a view.

#import "MaterialSpritedAnimationView.h"

// Create a Sprited Animation View.
UIImage *spriteSheet = [UIImage imageNamed:@"myImage"];
MDFSpritedAnimationView *animationView =
    [[MDFSpritedAnimationView alloc] initWithSpriteSheetImage:spriteSheet];
animationView.tintColor = [UIColor blueColor];
[self.view addSubview:animationView];

// To Animate.
[animationView startAnimatingWithCompletion:^(BOOL finished) {
    NSLog(@"Done animating.");
