iOS Circular Collection View Layout

Circular Collection View Layout for iOS layouts the collectionview items in a circular patterns.
You can customise the angle of the circle to be visible. Check out set up for customization


  • Universal device support (iPhone + iPad)
  • Easily stylable
  • Nice set of configuration options
  • Lightweight, simple and readable code.


Cocoa pods

DSCircularCollectionView is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "DSCircularCollectionView"

Manual Installation

  1. Download the zip
  2. Add the files under DSCircularCollectionView into your project.

Added insert and remove animations. Download sample to check the animations.




DSCircularLayout *circularLayout = [[DSCircularLayout alloc] init];
[circularLayout initWithCentre:CGPointMake(160, 160)
itemSize:CGSizeMake(50, 50)
[circularLayout setStartAngle:M_PI endAngle:0];
circularLayout.scrollDirection = UICollectionViewScrollDirectionHorizontal;
[collectionView setCollectionViewLayout:circularLayout];
  • Init the DSCircularLayout object with centre of the circle, radius of the circle, item size and spacing between each collection view cell
  • Set the visible angle in the circle with start and end angle. specify startAngle to endAndle in clock wise. (Default M_PI to 0)
  • Set the scrollDirection to UICollectionViewScrollDirectionHorizontal/Vertical (Default Vertical) *


@property (nonatomic, assign) UICollectionViewScrollDirection scrollDirection;

@property (nonatomic, assign) BOOL mirrorX;

@property (nonatomic, assign) BOOL mirrorY;

@property (nonatomic, assign) BOOL rotateItems;

- rotateItems (Default : NO)

Enabling this to YES, will rotate items based on the angle where they are in the circle.

- scrollDirection

Based on the angle of visibility choose the scroll direction (Horizintal or Vertical). For a visibility angle between M_PI to 0 horizontal scroll works, where as for M_PI/2 to 3M_PI.2 vertical scroll works. So choose scrollDirection wisely

- mirrorX, mirrorY (Default : NO)

For a particular visibility angle(b/w start and end), it so happens that the scrolling behaves reverse. That is, the layout will scroll in the opposite direction to the user scroll. Supporting this odd begaviour would be too much of code with angles.

The best way is to find alternate visible angle and mirror it.

Reverse Scroll Proper Scroll
[circularLayout setStartAngle:2*M_PI endAngle:M_PI]; circularLayout.mirrorX = NO; circularLayout.mirrorY = NO; [circularLayout setStartAngle:M_PI endAngle:0]; circularLayout.mirrorX = NO; circularLayout.mirrorY = YES;


To run the example project, clone the repo, and run pod install from the Example directory first
