MosaicGrid
MosaicGrid
is a SwiftUI library that provides both horizontal and vertical mosaic grid views, along with utility functions for customizing view tile sizes and placement. These components allow you to arrange multiple items in a visually appealing grid layout.
Example
To run the example project, clone the repo, and run pod install
from the Example directory first.
Requirements
- Swift 5.5 or higher
- iOS 16.0 or higher
- MacOS 13.0 or higher
- TVOS 16.0 or higher
- WatchOS 8.0 or higher
- Xcode 14 or higher
Installation
CocoaPods
You can easily install MosaicGrid via CocoaPods. Add the following line to your Podfile:
pod 'MosaicGrid', '~> 1.2.0'
Swift Package Manager (Xcode)
To install using Xcode's Swift Package Manager, follow these steps:
- Go to File > Swift Package > Add Package Dependency
- Enter the URL: https://github.com/hainayanda/MosaicGrid.git
- Choose Up to Next Major for the version rule and set the version to 1.2.0.
- Click "Next" and wait for the package to be fetched.
Swift Package Manager (Package.swift)
If you prefer using Package.swift, add MosaicGrid as a dependency in your Package.swift file:
dependencies: [
.package(url: "https://github.com/hainayanda/MosaicGrid.git", .upToNextMajor(from: "1.2.0"))
]
Then, include it in your target:
.target(
name: "MyModule",
dependencies: ["MosaicGrid"]
)
Usage
Mosaic Grid Arrangement
MosaicGrid
is similar to UICollectionView
, but with much more flexibility. MosaicGrid
will divide the view into grids (with spacing if have any) and allow you to utilize it for view placement.
How the placement will go will depend on the type of MosaicGrid you use, whether is it VMosaicGrid
or HMosaicGrid
. You can utilize usingGrids(h:v:)
to control how many tiles will be used for each view. With this, arranging UI with grid placement will be very easy!
Like this photo album example, or this abstract-like art :stuck_out_tongue_winking_eye:
VMosaicGrid
VMosaicGrid
is a vertical mosaic grid view. It will try to fill the horizontal grids then continue down and make the view grow to the bottom.
VMosaicGrid(hGridCount: 3, spacing: 2) {
ForEach(models) { model in
MyView(from: model)
.usingGrids(h: model.width, v: model.height)
}
}
The arrangement will be following this pattern:
You can customize how the grid size is calculated by using these 3 different init
:
public init(hGridCount: Int, spacing: MosaicGridSpacing = .zero, gridAspectRatio: Double = 1, @ViewBuilder content: @escaping () -> Content) { ... }
public init(hGridCount: Int, spacing: MosaicGridSpacing = .zero, gridHeight: CGFloat, @ViewBuilder content: @escaping () -> Content) { ... }
public init(gridSize: CGSize, minimumSpacing: MosaicGridSpacing = .zero, @ViewBuilder content: @escaping () -> Content) { ... }
If you don't want to specify the grid guide, you can use this init:
public init(spacing: MosaicGridSpacing = .zero, @ViewBuilder content: @escaping () -> Content) { ... }
But keep in mind that if you did not give any of hGridCount
or gridSize
, it will not calculate the grid guide, but it will place the view wherever it fit as compact as possible. usingGrids(h:v:)
will not work too since there is no grid guide.
HMosaicGrid
HMosaicGrid
is a horizontal mosaic grid view. It will try to fill the vertical grids then continue right and make the view grow to the right.
HMosaicGrid(vGridCount: 3, spacing: 2) {
ForEach(models) { model in
MyView(from: model)
.usingGrids(h: model.width, v: model.height)
}
}
The arrangement will be following this pattern:
You can customize how the grid size is calculated by using these 3 different init
:
public init(vGridCount: Int, spacing: MosaicGridSpacing = .zero, gridAspectRatio: Double = 1, @ViewBuilder content: @escaping () -> Content) { ... }
public init(vGridCount: Int, spacing: MosaicGridSpacing = .zero, gridWidth: CGFloat, @ViewBuilder content: @escaping () -> Content) { ... }
public init(gridSize: CGSize, minimumSpacing: MosaicGridSpacing = .zero, @ViewBuilder content: @escaping () -> Content) { ... }
If you don't want to specify the grid guide, you can use this init:
public init(spacing: MosaicGridSpacing = .zero, @ViewBuilder content: @escaping () -> Content) { ... }
But keep in mind that if you did not give any of vGridCount
or gridSize
, it will not calculate the grid guide, but it will place the view wherever it fit as compact as possible. usingGrids(h:v:)
will not work too since there is no grid guide.
SpacerTile
SpacerTile
is a utility function to create a clear rectangle with a given tile size. It is used if you want to make sure some grids are not occupied with a view.
VMosaicGrid(hGridCount: 3, spacing: 2) {
ForEach(models) { model in
MyView(from: model)
.usingGrids(h: model.width, v: model.height)
// spacer that fills grid 3x1
SpacerTile(h: 3, v: 1)
}
}
Keep in mind that if you did not give any of vGridCount
, hGridCount
, or gridSize
, SpacerTile will not work since there will be no grid guide.
MosaicGridSpacing
MosaicGridSpacing
is a struct representing horizontal and vertical spacing for Mosaic Grid. It's an object passed when creating MosaicGrid to represent spacing. Normally we can just use Double literal since this struct implements ExpressibleByFloatLiteral and ExpressibleByIntegerLiteral.
// Using Integer literal
VMosaicGrid(hGridCount: 3, spacing: 2) { ... }
// Using Double literal
VMosaicGrid(hGridCount: 3, spacing: 2.0) { ... }
// Using MosaicGridSpacing. h is horizontal spacing, v is vertical spacing
VMosaicGrid(hGridCount: 3, spacing: .init(h: 2, v: 2)) { ... }
