Usage

To use FMMosaicLayout in your UICollectionView, follow these steps:

Step 1: Import the framework

In your view controller file, import the FMMosaicLayout framework:

import FMMosaicLayout

Step 2: Create an instance of FMMosaicLayout

Create an instance of FMMosaicLayout and assign it to your UICollectionView’s collectionViewLayout property:


let mosaicLayout = FMMosaicLayout()
collectionView.collectionViewLayout = mosaicLayout

Step 3: Implement UICollectionViewDataSource

Implement the UICollectionViewDataSource methods to provide data for your collection view:


func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
// Return the number of items in your collection view
}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
// Return the cell for the specified index path
}

Customization

FMMosaicLayout provides several customization options to tailor the layout to your needs. You can customize the following properties:

Gaps

Specify the gaps between cells and sections using the following properties:

  • minimumInteritemSpacing: The minimum space between items in the same row/column.
  • minimumLineSpacing: The minimum space between rows/columns.
  • sectionInsets: The inset for each section (top, left, bottom, right).

Column Widths

To customize the column widths, you can set the columnWidthMode property to either .fixed or .dynamic:

  • .fixed: All columns will have the same fixed width.
  • .dynamic: Columns will have widths based on their content.

Transition Animation

FMMosaicLayout provides a built-in transition animation when inserting or deleting items. You can customize the animation duration using the animationDuration property.

Example

Here is an example of how to use FMMosaicLayout in your app:


// Import the framework
import FMMosaicLayout

class ViewController: UIViewController, UICollectionViewDataSource {

@IBOutlet weak var collectionView: UICollectionView!

override func viewDidLoad() {
super.viewDidLoad()

// Create an instance of FMMosaicLayout
let mosaicLayout = FMMosaicLayout()
collectionView.collectionViewLayout = mosaicLayout

// Set up your collection view
collectionView.dataSource = self
// ...
}

// Implement UICollectionViewDataSource methods

}

Conclusion

FMMosaicLayout is a versatile and lightweight library that simplifies the creation of mosaic layouts in your UICollectionView. With its customizable options and easy integration, you can create beautiful and dynamic layouts in no time.
