Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

To integrate SlideController into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.0'
use_frameworks!

target '<Your Target Name>' do
    pod 'CampcotCollectionView'
end

Then, run the following command:

$ pod install

Usage

import CampcotCollectionView
  1. Create CollectionView
let campcotCollectionView = CampcotCollectionView()
  1. Add campcotCollectionView to view hierarchy.
  2. Call toggle method on campcotCollectionView.
public func toggle(to section: Int,
                   offsetCorrection: CGFloat = default,
                   animated: Bool,
                   completion: ((Bool) -> Void)? = default)

Documentation

CampcotCollectionView

A Boolean value that determines whether the sections are expanded.

public var isExpanded: Bool { get }

Expands all the sections. Pins a section at index section to the top of view bounds.
offsetCorrection - the offset for pinned section from the top. Default value of offsetCorrection is 0.
animated - if true expands sections with animation.
completion - callback for animation.

public func expand(from section: Int,
                   offsetCorrection: CGFloat = default,
                   animated: Bool, 
                   completion: ((Bool) -> Void)? = default)

Collapses all the sections. Pins a section at index section to the top of view bounds.
offsetCorrection - the offset for pinned section from the top. Default value of offsetCorrection is 0.
animated - if true collapses sections with animation.
completion - callback for animation.

public func collapse(to section: Int,
                     offsetCorrection: CGFloat = default,
                     animated: Bool,
                     completion: ((Bool) -> Void)? = default)

Toggles current state from collapsed to expaned and vise versa. Pins a section at index section to the top of view bounds.
offsetCorrection - the offset for pinned section from the top. Default value of offsetCorrection is 0.
animated - if true toggles sections with animation.
completion - callback for animation.

public func toggle(to section: Int,
                   offsetCorrection: CGFloat = default,
                   animated: Bool,
                   completion: ((Bool) -> Void)? = default)
