In addition to basic static animations, it supports spring and decay dynamic animations, making it useful for building realistic, physics-based interactions. The API allows quick integration with existing Objective-C codebases and enables the animation of any property on any object. It's a mature and well-tested framework that drives all the animations and transitions in [Paper](http://www.facebook.com/paper). 4 | 5 | [![Build Status](https://travis-ci.org/facebook/pop.svg)](https://travis-ci.org/facebook/pop) 6 | 7 | ## Installation 8 | 9 | Pop is available on [CocoaPods](http://cocoapods.org). Just add the following to your project Podfile: 10 | 11 | ```ruby 12 | pod 'pop', '~> 1.0' 13 | ``` 14 | 15 | Bugs are first fixed in master and then made available via a designated release. If you tend to live on the bleeding edge, you can use Pop from master with the following Podfile entry: 16 | 17 | ```ruby 18 | pod 'pop', :git => 'https://github.com/facebook/pop.git' 19 | ``` 20 | 21 | ## Non-CocoaPods Installation 22 | 23 | ### iOS 8 Embedded Framework 24 | By adding the project to your project and adding pop.embedded framework to the Embedded Binaries section on the General tab of your app's target, you can set up pop in seconds! This also enables `@import pop` syntax with header modules. 25 | 26 | **Note**: because of some awkward limitations with Xcode, embedded binaries must share the same name as the module and must have `.framework` as an extension. This means that you'll see three pop.frameworks when adding embedded binaries (one for OS X, one for tvOS, and one for iOS). You'll need to be sure to add the iOS one, and since this list is populated in order of targets, it's safe to assume it's the second one. You can verify the correct one was chosen by checking the path next to the framework listed: `Debug-iphoneos`. The same principle applies on tvOS but instead of `Debug-iphoneos` look for `Debug-appletvos`. 27 | 28 | ![Embedded Binaries](Images/EmbeddedBinaries.png?raw=true) 29 | 30 | **Note 2**: this method does not currently play nicely with workspaces. For some unknown reason, Xcode simply rejects adding pop.framework as an embedded binary when pop.xcodeproj is placed in the workspace. This only works when pop.xcodeproj is added as a subproject to the current target's project. 31 | 32 | ### Advanced 33 | Alternatively, you can add the project to your workspace and adopt the provided configuration files or manually copy the files under the pop subdirectory into your project. If installing manually, ensure the C++ standard library is also linked by including `-lc++` to your project linker flags. 34 | 35 | ## Usage 36 | 37 | Pop adopts the Core Animation explicit animation programming model. Use by including the following import: 38 | 39 | ```objective-c 40 | #import 41 | ``` 42 | 43 | or if you're using the embedded framework: 44 | 45 | ```objective-c 46 | @import pop; 47 | ``` 48 | 49 | ### Start, Stop & Update 50 | 51 | To start an animation, add it to the object you wish to animate: 52 | 53 | ```objective-c 54 | POPSpringAnimation *anim = [POPSpringAnimation animation]; 55 | ... 56 | [layer pop_addAnimation:anim forKey:@"myKey"]; 57 | ``` 58 | 59 | To stop an animation, remove it from the object referencing the key specified on start: 60 | 61 | ```objective-c 62 | [layer pop_removeAnimationForKey:@"myKey"]; 63 | ``` 64 | 65 | The key can also be used to query for the existence of an animation. Updating the toValue of a running animation can provide the most seamless way to change course: 66 | 67 | ```objective-c 68 | anim = [layer pop_animationForKey:@"myKey"]; 69 | if (anim) { 70 | /* update to value to new destination */ 71 | anim.toValue = @(42.0); 72 | } else { 73 | /* create and start a new animation */ 74 | .... 75 | } 76 | ``` 77 | 78 | While a layer was used in the above examples, the Pop interface is implemented as a category addition on NSObject. Any NSObject or subclass can be animated. 79 | 80 | ### Types 81 | 82 | There are four concrete animation types: spring, decay, basic and custom. 83 | 84 | Spring animations can be used to give objects a delightful bounce. In this example, we use a spring animation to animate a layer's bounds from its current value to (0, 0, 400, 400): 85 | 86 | ```objective-c 87 | POPSpringAnimation *anim = [POPSpringAnimation animationWithPropertyNamed:kPOPLayerBounds]; 88 | anim.toValue = [NSValue valueWithCGRect:CGRectMake(0, 0, 400, 400)]; 89 | [layer pop_addAnimation:anim forKey:@"size"]; 90 | ``` 91 | Decay animations can be used to gradually slow an object to a halt. In this example, we decay a layer's positionX from it's current value and velocity 1000pts per second: 92 | 93 | ```objective-c 94 | POPDecayAnimation *anim = [POPDecayAnimation animationWithPropertyNamed:kPOPLayerPositionX]; 95 | anim.velocity = @(1000.); 96 | [layer pop_addAnimation:anim forKey:@"slide"]; 97 | ``` 98 | 99 | Basic animations can be used to interpolate values over a specified time period. To use an ease-in ease-out animation to animate a view's alpha from 0.0 to 1.0 over the default duration: 100 | ```objective-c 101 | POPBasicAnimation *anim = [POPBasicAnimation animationWithPropertyNamed:kPOPViewAlpha]; 102 | anim.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; 103 | anim.fromValue = @(0.0); 104 | anim.toValue = @(1.0); 105 | [view pop_addAnimation:anim forKey:@"fade"]; 106 | ``` 107 | `POPCustomAnimation` makes creating custom animations and transitions easier by handling CADisplayLink and associated time-step management. See header for more details. 108 | 109 | 110 | ### Properties 111 | 112 | The property animated is specified by the `POPAnimatableProperty` class. In this example we create a spring animation and explicitly set the animatable property corresponding to `-[CALayer bounds]`: 113 | 114 | ```objective-c 115 | POPSpringAnimation *anim = [POPSpringAnimation animation]; 116 | anim.property = [POPAnimatableProperty propertyWithName:kPOPLayerBounds]; 117 | ``` 118 | 119 | The framework provides many common layer and view animatable properties out of box. You can animate a custom property by creating a new instance of the class. In this example, we declare a custom volume property: 120 | 121 | ```objective-c 122 | prop = [POPAnimatableProperty propertyWithName:@"com.foo.radio.volume" initializer:^(POPMutableAnimatableProperty *prop) { 123 | // read value 124 | prop.readBlock = ^(id obj, CGFloat values[]) { 125 | values[0] = [obj volume]; 126 | }; 127 | // write value 128 | prop.writeBlock = ^(id obj, const CGFloat values[]) { 129 | [obj setVolume:values[0]]; 130 | }; 131 | // dynamics threshold 132 | prop.threshold = 0.01; 133 | }]; 134 | 135 | anim.property = prop; 136 | ``` 137 | 138 | For a complete listing of provided animatable properties, as well more information on declaring custom properties see `POPAnimatableProperty.h`. 139 | 140 | 141 | ### Debugging 142 | 143 | Here are a few tips when debugging. Pop obeys the Simulator's Toggle Slow Animations setting. Try enabling it to slow down animations and more easily observe interactions. 144 | 145 | Consider naming your animations. This will allow you to more easily identify them when referencing them, either via logging or in the debugger: 146 | 147 | ```objective-c 148 | anim.name = @"springOpen"; 149 | ``` 150 | 151 | Each animation comes with an associated tracer. The tracer allows you to record all animation-related events, in a fast and efficient manner, allowing you to query and analyze them after animation completion. The below example starts the tracer and configures it to log all events on animation completion: 152 | 153 | ```objective-c 154 | POPAnimationTracer *tracer = anim.tracer; 155 | tracer.shouldLogAndResetOnCompletion = YES; 156 | [tracer start]; 157 | ``` 158 | 159 | See `POPAnimationTracer.h` for more details. 160 | 161 | ## Testing 162 | 163 | Pop has extensive unit test coverage. To install test dependencies, navigate to the root pop directory and type: 164 | 165 | ```sh 166 | pod install 167 | ``` 168 | 169 | Assuming CocoaPods is installed, this will include the necessary OCMock dependency to the unit test targets. 170 | 171 | ## SceneKit 172 | 173 | Due to SceneKit requiring iOS 8 and OS X 10.9, POP's SceneKit extensions aren't provided out of box. Unfortunately, [weakly linked frameworks](https://developer.apple.com/library/mac/documentation/MacOSX/Conceptual/BPFrameworks/Concepts/WeakLinking.html) cannot be used due to issues mentioned in the [Xcode 6.1 Release Notes](https://developer.apple.com/library/ios/releasenotes/DeveloperTools/RN-Xcode/Chapters/xc6_release_notes.html). 174 | 175 | To remedy this, you can easily opt-in to use SceneKit! Simply add this to the Preprocessor Macros section of your Xcode Project: 176 | 177 | ``` 178 | POP_USE_SCENEKIT=1 179 | ``` 180 | 181 | ## Resources 182 | 183 | A collection of links to external resources that may prove valuable: 184 | 185 | * [AGGeometryKit+POP - Animating Quadrilaterals with Pop](https://github.com/hfossli/aggeometrykit-pop) 186 | * [Apple – Core Animation Programming Guide](https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/CoreAnimation_guide/Introduction/Introduction.html) 187 | * [iOS Development Tips – UIScrollView-like deceleration with Pop](http://iosdevtips.co/post/84571595353/replicating-uiscrollviews-deceleration-with-facebook) 188 | * [Pop Playground – Repository of Pop animation examples](https://github.com/callmeed/pop-playground) 189 | * [Pop Playground 2 – Playing with Facebook's framework](http://victorbaro.com/2014/05/pop-playground-playing-with-facebooks-framework/) 190 | * [POP-MCAnimate – Concise syntax for the Pop animation framework](https://github.com/matthewcheok/POP-MCAnimate) 191 | * [Popping - Great examples in one project](https://github.com/schneiderandre/popping) 192 | * [Rebound – Spring Animations for Android](http://facebook.github.io/rebound/) 193 | * [Tapity Tutorial – Getting Started with Pop](http://tapity.com/tutorial-getting-started-with-pop/) 194 | * [Tweaks – Easily adjust parameters for iOS apps in development](https://github.com/facebook/tweaks) 195 | * [POP Tutorial in 5 steps](https://github.com/maxmyers/FacebookPop) 196 | * [VBFPopFlatButton – Flat animatable button, using Pop to transition between states](https://github.com/victorBaro/VBFPopFlatButton) 197 | 198 | ## Contributing 199 | See the CONTRIBUTING file for how to help out. 200 | 201 | ## License 202 | 203 | Pop is released under a BSD License.
