Simple cover animation flow layout for collection view.
This custom layout enhances your collection view with cover flow effect.
You don’t need to worry about items(cells) positions, spaces between them, etc. because it’s already done in
YRCoverFlowLayout! You simply design your cell and return them as usual in datasource methods and
YRCoverFlowLayout handles the rest.
YRCoverFlowLayout is available through CocoaPods. To install
it, simply add the following line to your Podfile:
There are 4 properties that can be customized:
Max degree of rotation for items. Default to 45. This means that item on a left side of screen will be rotated 45 degrees around y and item on a right side will be rotated -45 degrees around y.
@property (nonatomic) CGFloat maxCoverDegree;
This property means how neighbour items are placed to in relation to currently displayed item. Default to 1/4. This means that item on left will cover 1/4 of current displayed item and item from right will also cover 1/4 of current item. Value should be in 0..1 range.
@property (nonatomic) CGFloat coverDensity;
Thanks to viteinfinite for adding 2 more customizable properties:
Min opacity that can be applied to individual item. Default to 1.0 (alpha 100%).
@property (nonatomic) CGFloat minCoverOpacity;
Min scale that can be applied to individual item. Default to 1.0 (no scale).
@property (nonatomic) CGFloat minCoverScale;
If you’re changing them at runtime - don’t forget to call ‘reloadData’.
Currently only horizontal scroll direction supported. In future releases vertical scrolling will be added too.
