It comes with a paginated effect and it shrinks and makes transparent the side items. 5 | 6 | ![demo](images/demo.gif) 7 | 8 | ## Requirements 9 | 10 | - iOS 8.1+ 11 | 12 | ## Installation 13 | 14 | ### CocoaPods 15 | 16 | `UPCarouselFlowLayout` is available through [CocoaPods](http://cocoapods.org). To install 17 | it, simply add the following line to your Podfile: 18 | 19 | ``` 20 | pod "UPCarouselFlowLayout" 21 | ``` 22 | 23 | ### Carthage 24 | 25 | Users can simply add to their Cartfile: 26 | 27 | ``` 28 | github "ink-spot/UPCarouselFlowLayout" 29 | ``` 30 | 31 | ### Manual 32 | 33 | Simply copy the folder `UPCarouselFlowLayout` to your project and import it in XCode. 34 | 35 | ## Usage 36 | 37 | ### Getting Started 38 | 39 | ##### Via code 40 | 41 | ```swift 42 | import UPCarouselFlowLayout 43 | ``` 44 | 45 | Create a `UPCarouselFlowLayout` object, set its `itemSize` and assign it to your `UICollectionView`. 46 | 47 | ```swift 48 | let layout = UPCarouselFlowLayout() 49 | layout.itemSize = CGSizeMake(200, 200) 50 | collectionView.collectionViewLayout = layout 51 | ``` 52 | 53 | ##### Via Interface Builder 54 | 55 | Set the `UICollectionView` layout class to `UPCarouselFlowLayout`, and set its `itemSize` and its properties. 56 | 57 | ![demo](images/ib_settings.png) 58 | 59 | ### Properties 60 | 61 | `UPCarouselFlowLayout` has a few customizable properties: 62 | 63 | * `sideItemScale` (between 0 and 1, default is 0.6) 64 | *Can be set through code or via Interface Builder.* 65 | The shrinking ratio for collection items which are not in the center. 66 | 67 | * `sideItemAlpha` (between 0 and 1, default is 0.6) 68 | *Can be set through code or via Interface Builder.* 69 | The opacity ratio for collection items which are not in the center. 70 | 71 | * `sideItemShift` (value in pixels, default is 0) 72 | *Can be set through code or via Interface Builder.* 73 | A vertical/horizontal offset (depending on the collectionView scroll direction) for collection items which are not in the center. 74 | 75 | * `spacingMode` (default is fixed spacing of 40 pts) 76 | *Can be set only through code.* 77 | * `UPCarouselFlowLayoutSpacingMode.fixed(spacing: CGFloat)` 78 | Items in the carousel are positioned with a fixed space between them. 79 | * `UPCarouselFlowLayoutSpacingMode.overlap(visibleOffset: CGFloat)` 80 | A fixed part of the side items are visible on the sides of the collection (and therefore the space between items depends on the collection size). 81 | 82 | 83 | ## License 84 | 85 | `UPCarouselFlowLayout` is released under the MIT license. 86 | See [LICENSE](./LICENSE) for details. 87 | -------------------------------------------------------------------------------- /UPCarouselFlowLayout.podspec: -------------------------------------------------------------------------------- 1 | Pod::Spec.new do |s| 2 | s.name = "UPCarouselFlowLayout" 3 | s.version = "1.1.2" 4 | s.summary = "A fancy carousel flow layout for UICollectionView." 5 | s.description = "UPCarouselFlowLayout is a fancy carousel flow layout for UICollectionView.
