4 | 5 | # Overview 6 | 7 | 8 | 9 | ## What is the `Gemini`? 10 | 11 | `Gemini` is rich scroll based animation framework for iOS, written in Swift. You can easily use `GeminiCollectionView`, which is a subclass of `UICollectionView`. 12 | 13 | It enables you to make multiple animation which has various and customizable properties, and moreover can create your own custom scroll animation. 14 | 15 | `Gemini` also provides a fluent interface based on method chaining. you can use this intuitively and simply. 16 | 17 | 18 | ```swift 19 | collectionView.gemini 20 | .circleRotationAnimation() 21 | .radius(400) 22 | .rotateDirection(.clockwise) 23 | ``` 24 | 25 | # Features 26 | 27 | ![Platform](http://img.shields.io/badge/platform-ios-blue.svg?style=flat 28 | ) 29 | [![Cocoapods](https://img.shields.io/badge/Cocoapods-compatible-brightgreen.svg)](https://img.shields.io/badge/Cocoapods-compatible-brightgreen.svg) 30 | [![Carthage compatible](https://img.shields.io/badge/Carthage-Compatible-brightgreen.svg?style=flat)](https://github.com/Carthage/Carthage) 31 | [![License](http://img.shields.io/badge/license-MIT-lightgrey.svg?style=flat 32 | )](http://mit-license.org) 33 | ![Swift](https://img.shields.io/badge/swift-5.0-orange.svg) 34 | ![pod](https://img.shields.io/badge/pod-v1.4.0-red.svg) 35 | 36 | 37 | 38 | - [x] Rich animation with scrolling 39 | - [x] Easily usable 40 | - [x] Highly customizable 41 | - [x] Several types of animations and properties 42 | - [x] Supports vertical and horizontal flow layout 43 | - [x] Supports easing function 44 | - [x] Supports `Swift5.0` 45 | - [x] Fluent interfaces based on method chaining 46 | - [x] Compatible with `Carthage` 47 | - [x] Compatible with `CocoaPods` 48 | - [x] Example project with lots of stock animations 49 | - [x] And More... 50 | 51 | # Contents 52 | - [Animation Types and properties](#animation-types) 53 | - [Usage](#usage) 54 | - [Requirements](#requirements) 55 | - [Installation](#installation) 56 | - [Author](#author) 57 | 58 | # Animation Types and properties 59 | 60 | The following animation types are available. See sample code [here](https://github.com/shoheiyokoyama/Gemini/tree/master/Example/Gemini) for details. 61 | 62 | - [Cube](#cube) 63 | - [Circle Rotation](#circle-rotation) You can configure direction of rotation using the `CircleRotationDirection` 64 | - [3D vector rotation](#3d-vector-rotation) Each rotation types provide multiple rotation effect 65 | - [Roll Rotation](#roll-rotation) 66 | - [Pitch Rotation](#pitch-rotation) 67 | - [Yaw Rotation](#yaw-rotation) 68 | - [Scale](#scale) 69 | - [Custom](#custom) You can create your own custom scroll animation using multiple properties, rotation, scale, translation, etc. 70 | 71 | In addition, you can also customize the following properties for the above animation types. 72 | 73 | - BackgroundColor 74 | - CornerRadius 75 | - Alpha 76 | - [Easings](#easing-function) 77 | - [Shadow Effect](#shadow-effect) 78 | 79 | ## Cube 80 | 81 |

82 | 83 | 84 |

85 | 86 | It's a cube animation like Instagram. 87 | If you would like to customize the cube animation, change `cubeDegree`. 88 | If `cubeDegree` is 90, it moves like a regular hexahedron. 89 | 90 | ```swift 91 | collectionView.gemini 92 | .cubeAnimation() 93 | .cubeDegree(90) 94 | ``` 95 | 96 | ## CircleRotation 97 | 98 |

99 | 100 | 101 |

102 | 103 | An animation moves in a circle. You can change `circleRadius` and `CircleRotationDirection`. 104 | 105 | ```swift 106 | collectionView.gemini 107 | .circleRotationAnimation() 108 | .radius(450) // The radius of the circle 109 | .rotateDirection(.clockwise) // Direction of rotation. 110 | .itemRotationEnabled(true) // Whether the item rotates or not. 111 | ``` 112 | 113 | ## 3D vector rotation 114 | 115 | Available for `Roll`, `Pitch` and `Yaw` animation. These rotation animation are designed based on 3-Dimensional vector. Figure-1 shows direction of rotation based on device. 116 | 117 | ###### ***Figure-1*** Pitch, roll, and yaw axes ###### 118 |

119 | 120 |

121 | 122 | ###### Reference: [Event Handling Guide for UIKit Apps](https://developer.apple.com/library/content/documentation/EventHandling/Conceptual/EventHandlingiPhoneOS/HandlingProcessedDeviceMotionData.html#//apple_ref/doc/uid/TP40009541-CH27-SW1) 123 | 124 | ### Roll Rotation 125 | 126 |

127 | 128 | 129 |

130 | 131 | ### Pitch Rotation 132 | 133 |

134 | 135 | 136 |

137 | 138 | ### Yaw Rotation 139 | 140 |

141 | 142 | 143 |

144 | 145 | 146 | Each types of rotation animation has `RotationEffect`(e.g. `RollRotationEffect`) and degree of rotation. 147 | 148 | Customize `RotationEffect` (`up`, `down`, `sineWave`, `reverseSineWave`) and degree of rotation. 149 | 150 | In the case of `rollRotation`, like this: 151 | ```swift 152 | collectionView.gemini 153 | .rollRotationAnimation() 154 | .degree(45) 155 | .rollEffect(.rollUp) 156 | ``` 157 | 158 | ## Scale 159 | 160 |

161 | 162 | 163 |

164 | 165 | The `scaleUp` gradually increases frame size, `scaleDown` decreases. 166 | 167 | ```swift 168 | collectionView.gemini 169 | .scaleAnimation() 170 | .scale(0.75) 171 |    .scaleEffect(.scaleUp) // or .scaleDown 172 | ``` 173 | 174 | ## Custom 175 | 176 |

177 | 178 | 179 |

180 | 181 | You can flexibly and easily customize scroll animation. Customize properties of `GeminiAnimation.custom` such as `scale`, `scaleEffect`, `rotationAngle`, `translation`, `easing`, `shadowEffect`, `alpha`, `cornerRadius`, `backgroundColor`, `anchorPoint`, etc. 182 | 183 | The animation of gif is customized in the following way: 184 | 185 | ```swift 186 | collectionView.gemini 187 | .customAnimation() 188 | .translation(y: 50) 189 | .rotationAngle(y: 13) 190 | .ease(.easeOutExpo) 191 | .shadowEffect(.fadeIn) 192 | .maxShadowAlpha(0.3) 193 | ``` 194 | 195 | Or right side of gifs is customized as follows: 196 | 197 | ```swift 198 | collectionView.gemini 199 | .customAnimation() 200 | .backgroundColor(startColor: lightGreenColor, endColor: lightBlueColor) 201 | .ease(.easeOutSine) 202 | .cornerRadius(75) 203 | ``` 204 | 205 | There are more sample code at [CustomAnimationViewController.swift](https://github.com/shoheiyokoyama/Gemini/blob/master/Example/Gemini/ViewControllers/CustomAnimationViewController.swift). 206 | 207 | ## Easing function 208 | `Gemini` supports various easing functions based on distance of scroll. 209 | 210 | - linear 211 | - easeInQuad 212 | - easeOutQuad 213 | - easeInOutQuad 214 | - easeInCubic 215 | - easeOutCubic 216 | - easeInOutCubic 217 | - easeInQuart 218 | - easeOutQuart 219 | - easeInOutQuart 220 | - easeInQuint 221 | - easeOutQuint 222 | - easeInOutQuint 223 | - easeInSine 224 | - easeOutSine 225 | - easeInOutSine 226 | - easeInExpo 227 | - easeOutExpo 228 | - easeInOutExpo 229 | - easeInCirc 230 | - easeOutCirc 231 | - easeInOutCirc 232 | 233 | ## Shadow effect 234 | Default value is `ShadowEffect.none`. Return `shadowView` in your custom class, which is a subclass of `GeminiCell`. 235 | 236 | - fadeIn 237 | - nextFadeIn 238 | - previousFadeIn 239 | - fadeOut 240 | - none 241 | 242 | ```swift 243 | class CustomCollectionViewCell: GeminiCell { 244 | @IBOutlet weak var customShadowView: UIView! 245 | override var shadowView: UIView? { 246 | return customShadowView 247 | } 248 | } 249 | ``` 250 | 251 | # Usage 252 | 253 | 1. ***Use Gemini classes*** 254 | 255 | `Gemini` is designed to be easy to use. Use `GeminiCollectionView` and `GeminiCell`. These classes is subclass of `UICollectionView`, `UICollectionViewCell`. 256 | 257 | 2. ***Configure animation*** 258 | 259 | Configure animation with fluent interface based on method chaining. You can develop expressive code that enhances readability. 260 | 261 | 3. ***Call function for animation*** 262 | 263 | Finally, call `animateVisibleCells()` in `scrollViewDidScroll(_:)` 264 | 265 | > NOTE: If you want to adapt animation immediately after view is displayed, call `animateCell(_:)` in `collectionView(_:cellForItemAt:)` and `collectionView(_:willDisplay:forItemAt:)`. 266 | 267 | 268 | ```swift 269 | // Import Gemini 270 | import Gemini 271 | 272 | // Inherite GeminiCell 273 | class CustomCell: GeminiCell { 274 | ... 275 | } 276 | 277 | // Conform to UICollectionViewDelegate and UICollectionViewDataSource 278 | class CustomViewController: UIViewController: UICollectionViewDelegate, UICollectionViewDataSource { 279 | 280 | // Inherite GeminiCollectionView 281 | @IBOutlet weak var collectionView: GeminiCollectionView! 282 | 283 | ... 284 | 285 | // Configure animation and properties 286 | func configureAnimation() { 287 | collectionView.gemini 288 | .circleRotationAnimation() 289 | .radius(400) 290 | .rotateDirection(.clockwise) 291 | } 292 | 293 | // Call animation function 294 | func scrollViewDidScroll(_ scrollView: UIScrollView) { 295 | collectionView.animateVisibleCells() 296 | } 297 | 298 | func collectionView(_ collectionView: UICollectionView, willDisplay cell: UICollectionViewCell, forItemAt indexPath: IndexPath) { 299 | if let cell = cell as? GeminiCell { 300 | self.collectionView.animateCell(cell) 301 | } 302 | } 303 | 304 | func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { 305 | let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CustomCell", for: indexPath) as! CustomCell 306 | self.collectionView.animateCell(cell) 307 | return cell 308 | } 309 | ``` 310 | 311 | See [Example](https://github.com/shoheiyokoyama/Gemini/tree/master/Example/Gemini), for more details. 312 | 313 | To run the example project, clone the repo, and run `pod install` from the Example directory first. 314 | 315 | ## Requirements 316 | 317 | - Xcode 10.2.1 318 | - Swift 5.0 319 | 320 | ## Installation 321 | 322 | ### CocoaPods 323 | 324 | Gemini is available through [CocoaPods](http://cocoapods.org).
