HK UIButton Enhancements

IMPORTANT!!

You MUST include this script at the end of your Podfile or the Inspectables won't work.

# This post_install section fixes a bug in CocoaPod that does not allow
# IBDesignables to render in interface builder

        post_install do |installer|
        installer.pods_project.targets.each do |target|
            target.new_shell_script_build_phase.shell_script = "mkdir -p $PODS_CONFIGURATION_BUILD_DIR/#{target.name}"
                target.build_configurations.each do |config|
                    config.build_settings['CONFIGURATION_BUILD_DIR'] = '$PODS_CONFIGURATION_BUILD_DIR'
                    config.build_settings.delete('CODE_SIGNING_ALLOWED')
                    config.build_settings.delete('CODE_SIGNING_REQUIRED')
                end
            end

INTRODUCTION

This class descends from UIButton and provides these enhancements and a designable user interface in Xcode Interface Builder.

Dynamic Corner Radius

This class descends from UIButton and provides the functionalities to calculate a corner radius dynamically base on one of the sides. It uses the methods in HKUIViewAutoCornerExtension as a base.

Highlighted and Selected State Customization

It lets users customize the border color, width, alpha of the highlighted, normal and selected states

Dynamic Text Size

The text size can change dynamically, adopting to different dimensions just like the corner radius.

HOW IT WORKS

It overrides these four methods to provide the values to HKUIViewAutoCornerExtension.

    @objc open func autoCornerRoundingBasis() -> LengthCalculationBasis

    @objc open func autoCornerRoundingConstant() -> CGFloat

    @objc open func autoCornerRoundingEnabled() -> Bool

    @objc open func autoCornerRoundingFactor() -> CGFloat

It call this method of HKUIViewAutoCornerExtension when it needs to redraw.

    public func updateCornerRadius()

INSTALLATION

Manually:

Include in your project

  HKUIButton.swift
  UIView+HKAutoCornerRounding.swift
  UIView+LengthCalculationBasis.swift

Or use CocoaPod. Don't forget to import the module if you are using CocoaPod:

  import HKUIButton
