Spots 6.1.2




Spots is a cross-platform view controller framework for building component-based UIs. The internal architecture is built using generic view models that can be transformed both to and from JSON. So, moving your UI declaration to a backend is as easy as pie.
Data source and delegate setup is handled by Spots, so there is no need for you to do that manually. The public API is jam-packed with convenience methods for performing mutation, it is as easy as working with a regular collection type.

Getting started with Spots

If you are looking for a way to get started with Spots, we recommend taking a look at our Getting started guide.

Origin Story

We wrote a Medium article about how and why we built Spots.

Universal support

Apple's definition of a universal applications is iPhone and iPad. Spots takes this a step further with one controller tailored to each platform to support all your UI related update needs. Internally, everything conforms to the same shared protocol. What this means for you, is that get a unified experience when developing for iOS, tvOS or macOS.

Usage

Use the following links to dive a bit deeper into how Spots works.

How does it work?

At the top level of Spots, you have the SpotsController which is the replacement for your view controller.

Inside of the SpotsController, you have a SpotsScrollView that handles the linear layout of the components that you add to your data source. It is also in charge of giving the user a unified scrolling experience. Scrolling is disabled on all underlaying components except for components that have horizontal scrolling.

So how does scrolling work? Whenever a user scrolls, the SpotsScrollView computes the offset and size of its children. By using this technique you can easily create screens that contain lists, grids and carousels with a scrolling experience as smooth as proverbial butter. By dynamically changing the size and offset of the children, SpotsScrollView also ensures that reusable views are allocated and deallocated like you would expect them to.
SpotsScrollView uses KVO on any view that gets added so if one component changes height or position, the entire layout will invalidate itself and redraw it like it was intended.

SpotsController supports multiple Component's, each represent their own UI container and hold their own data source. Components all share the same data model called ComponentModel, it includes layout, interaction and view model data. Component gets its super-powers from protocol extensions, powers like mutation, layout processing and convenience methods for accessing model information.

Key features

  • JSON based views that could be served up by your backend.
  • Live editing.
  • View based caching for controllers, table and collection views.
  • Supports displaying multiple collections, tables and regular views in the same container.
  • Features both infinity scrolling and pull to refresh (on iOS), all you have to do is to
    setup delegates that conform to the public protocols on SpotsController.
  • No need to implement your own data source, every Component has its
    own set of Item’s.
    which is maintained internally and is there at your disposable if you decide to
    make changes to them.
  • Easy configuration for registering views.
    This improves code reuse and helps to theme your app and ultimately keep your application consistent.
  • A rich public API for appending, prepending, inserting, updating or
    deleting Items.
  • Has built-in support for regular views inside of both collection and table views.
    Write one view and use it across your application, when and where you want to use it.
  • Supports view states such as normal, highlighted and selected.
  • View height caching that improves performance as each view has its height stored as a calculated value.
    on the view model.
  • Supports multiple views inside the same data source, no more ugly if-statements in your implementation;
  • Soft & hard updates to UI components.
  • Supports both views made programmatically and nib-based views.
    Spots handles this for you by using a view registry.
