## 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. Aaaand it also supports **multi-line** tags 🚀

## Usage

- Init Method:

```swift
import TagCellLayout

let tagCellLayout = TagCellLayout(alignment: .center, delegate: self)
collectionView.collectionViewLayout = tagCellLayout
```

- Tag Alignment:

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


## Delegate Methods
- Protocol to conform - `TagCellLayoutDelegate`


- Methods


```swift
- 	func tagCellLayoutTagSize(layout: TagCellLayout, atIndex index:Int) -> CGSize
```

## Architecture

- ```func tagCellLayoutTagSize(layout: TagCellLayout, atIndex index:Int) -> CGSize``` 

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

- ```collectionView.numberOfItemsInSection(0)```

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