Welcome to the documentation for the DGCollectionViewLeftAlignFlowLayout library – a custom layout for UICollectionView that left aligns the cells instead of centering them.
Installation
CocoaPods
To integrate DGCollectionViewLeftAlignFlowLayout into your Xcode project using CocoaPods, add the following line to your Podfile:
“`ruby
pod ‘DGCollectionViewLeftAlignFlowLayout’
“`
Manual
If you prefer not to use CocoaPods, you can manually add the library to your project. Follow these steps:
- Download the latest release from the GitHub repository: DGCollectionViewLeftAlignFlowLayout.
- Unzip the downloaded file.
- Drag and drop the “DGCollectionViewLeftAlignFlowLayout” folder into your Xcode project.
- Make sure to check the “Copy items if needed” option when prompted.
Usage
Import
First, import the DGCollectionViewLeftAlignFlowLayout library in your view controller:
“`swift
import DGCollectionViewLeftAlignFlowLayout
“`
Initialize
Next, initialize a DGCollectionViewLeftAlignFlowLayout object and assign it to your UICollectionView’s collectionViewLayout property:
“`swift
let leftAlignFlowLayout = DGCollectionViewLeftAlignFlowLayout()
collectionView.collectionViewLayout = leftAlignFlowLayout
“`
Customization
DGCollectionViewLeftAlignFlowLayout provides several customization options using its properties:
Align Content Vertically
By default, the library aligns the cells vertically to the top of the collection view. You can change this by setting the alignContentVertically property to false
:
“`swift
leftAlignFlowLayout.alignContentVertically = false
“`
Item Spacing
You can control the spacing between items by adjusting the itemSpacing property. The default value is 10 points:
“`swift
leftAlignFlowLayout.itemSpacing = 20
“`
Line Spacing
To modify the spacing between lines (rows), you can set the lineSpacing property to your preferred value. The default is 10 points:
“`swift
leftAlignFlowLayout.lineSpacing = 20
“`
Section Inset
You can add insets (margins) around the collection view sections using the sectionInset property:
“`swift
leftAlignFlowLayout.sectionInset = UIEdgeInsets(top: 10, left: 20, bottom: 10, right: 20)
“`
Conclusion
Congratulations! You’ve successfully integrated DGCollectionViewLeftAlignFlowLayout into your project and customized its behavior. Enjoy using this custom layout to left align cells within your UICollectionView!
