FLKAutoLayout is a collection of categories on UIView which makes it easy to setup layout constraints in code. FLKAutoLayout creates simple constraints with a readable syntax and provides many convenience methods to setup more complex constraints between multiple views at once. It automatically adds the constraints to the nearest common superview of the views involved and sets the translatesAutoresizingMaskIntoConstraints property on those views to NO.
FXForms is an Objective-C library for easily creating table-based forms on iOS. It is ideal for settings pages or data-entry tasks. Unlike other solutions, FXForms works directly with strongly-typed data models that you supply, and infers as much information as possible from your models using introspection, to avoid the need for tedious duplication of type information.
