An extandable mosaic UICollectionViewLayout with a focus on extremely flexible customizations.

Note

This layout is not of waterfall type. It was designed for layouts where we can predict the size of rectangular box which contains the number of full cells. Check out how to copy TRMosaicLayout or FMMosaicLayout using SquareMosaicLayout

Example Layout Pattern Blocks

Build and run an example project to see how it really works Let’s imagine that we want a UICollectionView with some mosaic layout that looks like this The red part of frames repeats while scrolling. So we should do only the red pattern and then repeat it The pattern is split it into smaller blocks that can be reused for some other layout or pattern

Installation

SquareMosaicLayout is available through CocoaPods. To install
it, simply add the following line to your Podfile:

pod 'SquareMosaicLayout', '4.1.2'

Example – copying TRMosaicLayout

final class TRMosaicLayoutCopy: SquareMosaicLayout, SquareMosaicDataSource {

    convenience init() {
        self.init(direction: SquareMosaicDirection.vertical)
        self.dataSource = self
    }

    func layoutPattern(for section: Int) -> SquareMosaicPattern {
        return TRMosaicLayoutCopyPattern()
    }
}

class TRMosaicLayoutCopyPattern: SquareMosaicPattern {

    func patternBlocks() -> [SquareMosaicBlock] {
        return [
            TRMosaicLayoutCopyBlock1(),
            TRMosaicLayoutCopyBlock2()
        ]
    }
}

public class TRMosaicLayoutCopyBlock1: SquareMosaicBlock {

    public func blockFrames() -> Int {
        return 3
    }

    public func blockFrames(origin: CGFloat, side: CGFloat) -> [CGRect] {
        let minWidth = side / 3.0
        let maxWidth = side - minWidth
        let minHeight = minWidth * 1.5
        let maxHeight = minHeight + minHeight
        var frames = [CGRect]()
        frames.append(CGRect(x: 0, y: origin, width: maxWidth, height: maxHeight))
        frames.append(CGRect(x: maxWidth, y: origin, width: minWidth, height: minHeight))
        frames.append(CGRect(x: maxWidth, y: origin + minHeight, width: minWidth, height: minHeight))
        return frames
    }
}

public class TRMosaicLayoutCopyBlock2: SquareMosaicBlock {

    public func blockFrames() -> Int {
        return 3
    }

    public func blockFrames(origin: CGFloat, side: CGFloat) -> [CGRect] {
        let minWidth = side / 3.0
        let maxWidth = side - minWidth
        let minHeight = minWidth * 1.5
        let maxHeight = minHeight + minHeight
        var frames = [CGRect]()
        frames.append(CGRect(x: 0, y: origin, width: minWidth, height: minHeight))
        frames.append(CGRect(x: 0, y: origin + minHeight, width: minWidth, height: minHeight))

Example – copying FMMosaicLayout

final class FMMosaicLayoutCopy: SquareMosaicLayout, SquareMosaicDataSource {

    convenience init() {

        self.dataSource = self
    }

        return FMMosaicLayoutCopyPattern()
    }

            FMMosaicLayoutCopyBlock2(),
            FMMosaicLayoutCopyBlock3(),
            FMMosaicLayoutCopyBlock2(),
            FMMosaicLayoutCopyBlock2()
        ]
    }
}

public class FMMosaicLayoutCopyBlock1: SquareMosaicBlock {

    public func blockFrames() -> Int {
        return 5
    }

    public func blockFrames(origin: CGFloat, side: CGFloat) -> [CGRect] {
        let min = side / 4.0
        let max = side - min - min
        var frames = [CGRect]()
        frames.append(CGRect(x: 0, y: origin, width: max, height: max))
        frames.append(CGRect(x: max, y: origin, width: min, height: min))

        frames.append(CGRect(x: max + min, y: origin + min, width: min, height: min))
        return frames
    }
}

public class FMMosaicLayoutCopyBlock2: SquareMosaicBlock {

    public func blockFrames() -> Int {
        return 4
    }

    public func blockFrames(origin: CGFloat, side: CGFloat) -> [CGRect] {
