    KolodaView

    KolodaView

    Simplify the implementation of Tinder-like cards on iOS

    KolodaView is a class designed to simplify the implementation of Tinder-like cards on iOS. It adds convenient functionality such as a UITableView-style dataSource/delegate interface for loading views dynamically, and efficient view loading, unloading. KolodaView is subclassed from UIView and - as with all UIKit components, it should only be accessed from the main thread. You may wish to use threads for loading or updating KolodaView contents or items, but always ensure that once your content has loaded, you switch back to the main thread before updating the KolodaView. To install manually the KolodaView class in an app, just drag the KolodaView, DraggableCardView, OverlayView class files (demo files and assets are not needed) into your project. Also you need to install facebook-pop. Or add bridging header if you are using CocoaPods.

    Midnight.js

    Midnight.js

    Switch your nav's design on the fly

    A jQuery plugin that switches between multiple header designs as you scroll, so you always have a header that looks great with the content below it. Create your fixed nav (or header) as you typically would. Create your fixed nav (or header) as you typically would. You can use whatever markup suits you, just make sure the header works well with position:fixed. After that, take any sections of your page that need a different nav and add data-midnight="your-class" to it, where .your-class is the class you are going to use to style that header. If you don't use the property or just leave it blank, the .default class will be used for that section. You can style it in your CSS using the class .midnightHeader.your-class. Use whatever CSS or markup you like for each one. They will be switched automatically when necessary. To make everything work, just load midnight (and jQuery) and initialize it. We take care of the rest.

    TOCropViewController

    TOCropViewController

    View controller for iOS that allows users to crop portions of UIImage

    TOCropViewController is an open-source UIViewController subclass to crop out sections of UIImage objects, as well as perform basic rotations. It is excellent for things like editing profile pictures, or sharing parts of a photo online. It has been designed with the iOS Photos app editor in mind, and as such, behaves in a way that should already feel familiar to users of iOS. For Swift developers, CropViewController is a Swift wrapper that completely encapsulates TOCropViewController and provides a much more native, Swiftier interface. The choice of having the controller return the cropped image to a delegate, or immediately pass it to a UIActivityViewController. A custom animation and layout when the device is rotated to landscape mode. Custom 'opening' and 'dismissal' animations. Localized in 28 languages.

    UIImageColors

    Fetches the most dominant and prominent colors from an image

    iTunes style color fetcher for UIImage and NSImage. It fetches the most dominant and prominent colors. UIImageColorsQuality is a enum with four different qualities. The qualities refer to how much the original image is scaled down. Lowest implies a smaller size and faster performance at the cost of quality colors. High implies a larger size with slower performance with good colors. The highest implies no downscaling and very good colors, but it is very slow.

    UITableView-FDTemplateLayoutCell

    UITableView-FDTemplateLayoutCell

    Template auto layout cell for UITableViewCell

    UITableView-FDTemplateLayoutCell is an Objective-C utility for automatically calculating and caching UITableViewCell heights using Auto Layout, improving performance and streamlining dynamic cell sizing. Generally, no need to care about modes; it will automatically choose a proper mode by whether you have set auto layout constraints on cell's content view. Works seamlessly with Storyboard, nibs, or programmatically registered cells. If you want to enforce frame layout mode, enable this property in your cell's configuration block. A fully self-satisfied cell is constrained by auto layout, and each edge has at least one layout constraint against it. It's the same concept introduced as "self-sizing cell" in iOS8 using auto layout.

    View Controller Transitions Library

    View Controller Transitions Library

    Collection of iOS7 animation controllers and interaction controllers

    View Controller Transitions Library is a collection of iOS7 animation controllers and interaction controllers, providing flip, fold and all kinds of other transitions. With iOS 7 you can easily create custom view controller transitions that can be used in a range of contexts (push, pop, modal, etc.) This project provides a library of custom animations which can be dropped directly into your project. It also has a number of 'interaction controllers' which can be used with any of the custom animations in order to make your transitions interactive. Animation and interaction controllers are entirely independent, this means you can wire up any interaction controller with any animation controller, which is pretty awesome. When you indicate that a custom transition should be used, you provide an animation controller. This class performs the required animation, then informs the framework when it has completed.

    uix-kit

    uix-kit

    A free web kits for fast web design and development

    Uix Kit is not a framework, just a UI toolkit based on some common libraries for building beautiful responsive website. Uix Kit isn't a reusable component structure, mostly custom CSS and JavaScript based. Definitely interesting, and if you're developing mostly web content and not applications this is particularly useful. It is a web dev build tool/scaffold that does not depend on any framework. You can import any external libraries/frameworks or native ES Modules for production. The generated core file in the dist directory can be used separately in any website. Support JS, HTML, and SASS component library automatically packaged. It is used to develop the full-static website (HTML templates or for dynamic language integration). The demo depends on jQuery (you can completely rewrite the script if needed). And dist DOES NOT bundle any third-party script and style library, all libraries are loaded externally in the HTML file.
