Full configurable spreadsheet view user interfaces for iOS applications. With this framework, you can easily create complex layouts like schedule, Gantt chart, timetable as if you are using Excel.
- Fixed column and row headers
- Merge cells
- Circular infinite scrolling automatically
- Customize gridlines and borders for each cell
- Customize inter cell spacing vertically and horizontally
- Fast scrolling, memory efficient
-
UICollectionViewlike API - Well unit tested

SpreadsheetView is written in Swift 5. Compatible with iOS 9.0+
SpreadsheetView is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod 'SpreadsheetView'For Carthage, add the following to your Cartfile:
github "kishikawakatsumi/SpreadsheetView"
The minimum requirement is connecting a data source to return the number of columns/rows, and each column width/row height.
import UIKit
import SpreadsheetView
class ViewController: UIViewController, SpreadsheetViewDataSource {
@IBOutlet weak var spreadsheetView: SpreadsheetView!
override func viewDidLoad() {
super.viewDidLoad()
spreadsheetView.dataSource = self
}
func numberOfColumns(in spreadsheetView: SpreadsheetView) -> Int {
return 200
}
func numberOfRows(in spreadsheetView: SpreadsheetView) -> Int {
return 400
}
func spreadsheetView(_ spreadsheetView: SpreadsheetView, widthForColumn column: Int) -> CGFloat {
return 80
}
func spreadsheetView(_ spreadsheetView: SpreadsheetView, heightForRow row: Int) -> CGFloat {
return 40
}
}Freezing a column or row behaves as a fixed column/row header.
func frozenColumns(in spreadsheetView: SpreadsheetView) -> Int {
return 2
}
func frozenRows(in spreadsheetView: SpreadsheetView) -> Int {
return 2
}
func frozenColumns(in spreadsheetView: SpreadsheetView) -> Int {
return 2
}
func frozenRows(in spreadsheetView: SpreadsheetView) -> Int {
return 2
}
Multiple cells can be merged and then they are treated as one cell. It is used for grouping cells.
func mergedCells(in spreadsheetView: SpreadsheetView) -> [CellRange] {
return [CellRange(from: (row: 1, column: 1), to: (row: 3, column: 2)),
CellRange(from: (row: 3, column: 3), to: (row: 8, column: 3)),
CellRange(from: (row: 4, column: 0), to: (row: 7, column: 2)),
CellRange(from: (row: 2, column: 4), to: (row: 5, column: 8)),
CellRange(from: (row: 9, column: 0), to: (row: 10, column: 5)),
CellRange(from: (row: 11, column: 2), to: (row: 12, column: 4))]
}
Your table acquires infinite scroll just set circularScrolling property.
spreadsheetView.circularScrolling = CircularScrolling.Configuration.horizontallyspreadsheetView.circularScrolling = CircularScrolling.Configuration.verticallyspreadsheetView.circularScrolling = CircularScrolling.Configuration.both
If circular scrolling is enabled, you can set additional parameters that the option not to repeat column/row header and to extend column/row header to the left/top edges. CircularScrolling.Configuration is a builder pattern, can easily select the appropriate combination by chaining properties.
e.g.
spreadsheetView.circularScrolling =
CircularScrolling.Configuration.horizontally.columnHeaderNotRepeatedspreadsheetView.circularScrolling =
CircularScrolling.Configuration.both.columnHeaderStartsFirstRowYou can customize the appearance of grid lines and borders of the cell. You can specify whether a cell has a grid line or border. Grid lines and borders can be displayed on the left, right, top, or bottom, or around all four sides of the cell.
The difference between gridlines and borders is that the gridlines are drawn at the center of the inter-cell spacing, but the borders are drawn to fit around the cell.
spreadsheetView.intercellSpacing = CGSize(width: 1, height: 1)
SpreadsheetView's gridStyle property is applied to the entire table.
spreadsheetView.gridStyle = .solid(width: 1, color: .lightGray)You can set different gridStyle for each cell and each side of the cell. If you set cell's gridStyle property to default, SpreadsheetView's gridStyle property will be applied. Specify none means the grid will not be drawn.
cell.gridlines.top = .solid(width: 1, color: .blue)
cell.gridlines.left = .solid(width: 1, color: .blue)
cell.gridlines.bottom = .none
cell.gridlines.right = .none
You can set different borderStyle for each cell as well.
cell.borders.top = .solid(width: 1, color: .red)
cell.borders.left = .solid(width: 1, color: .red)
cell.borders.bottom = .solid(width: 1, color: .red)
cell.borders.right = .solid(width: 1, color: .red)Kishikawa Katsumi, [email protected]
