LYPeacock

The set of Categories that will help you clean, reduce, order and separate all you styling code, removing it from your Views and ViewControllers to put it on a separate styling file.

Installation

To install the pod, add following line to your Podfile:

    pod "Peacock"

Usage

Peacock extends the existing properties that you can set with the UIAppearance protocol. In a way that you can effectively configure more than what UIView subclasses will allow you.

What is UIAppearance

It's a protocol that allows us to set some properties of UIView subclasses in an "asynchronous" way. We configure our subclasses and at the same time take out the styling code from the View Controllers / subviews. The OS will be in charge of applying the desired style just before he adds a view to the Screen.

Basic usage:

	[[UILabel appearance] setBackgroundColor:[UIColor whiteColor]];

Most of the custom created properties start with Lyst prefix LY.

    [[LYTitleLabel appearanceWhenContainedIn:[LYProductView class], nil] setLYFont:TitleFont];

There's a short video and blog post on how-to's and best practices for UIAppearance and Peacock.

Creating a theme file

We highly recommend creating a class to hold all your UI-styling code in a CSS-like fashion. And calling it as soon as possible when your app launches.

Import the global header file Peacock.h on any of your implementation files.

	#import "Peacock.h"

Configuring your Views

Peacock extends the available configurations of the appearance protocol. It's implementation should help configure all your views frome a single location keeping your views and controllers clean of UI-styling code.

Those are the properties and methods that Peacock extends so they can be available through the UIAppearance protocol.
