#TemplateKit

This software is still in alpha. Backward-incompatible changes will be made without notice.

TemplateKit is a framework for iOS view programming. Its goal is to become a default tool for implementing complex custom views with abstractions optimized for the most common cases.

TemplateKit provides an intuitive and efficient DSL to perform common tasks in view programming such as view hierarchy construction, data population, and layout. View code written with TemplateKit is much shorter and more readable than code written with the raw UIView API.

For example, to implement a classic table view cell with an image on the left and two stacked texts on the right like this:

you would just write:

// From SampleApp/Templates/FirstExample.m.

TPL_DEFINE_VIEW_TEMPLATE(first_example, FirstExampleView) {
  return row(image($(thumbnail)),
             margin(@10),
             column(label($(title)),
                    label($(subtitle)),
                    nil),
             nil)
           .padding(TPLEdgeInsetsMake(10, 10, 10, 10));
}

These seven lines of template code in the block is enough to tell the framework to construct a view hierarchy with one UIImageView instance and two UILabel instances, populate them with runtime data, and lay out the view hierarchy with the specified margin and paddings. Even a very simple view like this would take several dozens of lines if it were implemented with the raw UIView API.
