TagCellLayout

About

Its an ui-collection-view LAYOUT class that takes care of all the logic behind making tags like layout using UICollectionView. It also allows you to adjust the alignment of your layout i.e Left || Centre || Right. Now you just have to take care of your tag view and nothing else.

Installation

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'

pod 'TagCellLayout', '~> 0.2'

Usage

• Init Method:

import TagCellLayout

let tagCellLayout = TagCellLayout(tagAlignmentType: .Center, delegate: self)
collectionView.collectionViewLayout = tagCellLayout

• Tag Alignment:

tagAlignmentType can be Left or Center or Right. If its nil then by default Left alignment will be applied.

• Helper methods:

- func textWidth(text: String, font: UIFont) -> CGFloat

It calculates the width of a tag string.

Delegate Methods

• Protocol to conform - TagCellLayoutDelegate

• Methods

- func tagCellLayoutTagWidth(layout: TagCellLayout, atIndex index:Int) -> CGFloat
- func tagCellLayoutTagFixHeight(layout: TagCellLayout) -> CGFloat

Architecture

• tagCellLayoutTagFixHeight(layout: TagCellLayout)

is only called once as all tags have one fixed height that will be defined by this method.

• tagCellLayoutTagWidth(layout: TagCellLayout, atIndex index:Int)

is called for every tag where you will calculate their width and pass it on to TagCellLayout class for further calculations.

• collectionView.numberOfItemsInSection(0)

internally the number of tags is calculated by the above method.
