Swift DataTables

Twitter: @pavan_kataria

SwiftDataTables allows you to display grid-like data sets in a nicely formatted table for iOS. The main goal for the end-user is to be able to obtain useful information from the table as quickly as possible with the following features: ordering, searching, and paging; and to provide an easy implementation with extensible options for the developer.

Major Features include:

  • [x] Tested on iOS 8.0, 9, 10, 11, and 12 onwards.
  • [x] Full Swift 4 support
  • [x] Mobile friendly. Tables adapt to the viewport size.
  • [x] Instant search. Filter results by text search.
  • [x] Continued support and active development!
  • [x] Full Datasource and delegate support!
  • [x] Demo project available show casing all types of customisations
  • [x] Or easy plugin configuration object can be passed with default values for your swift data table's visual presentation.
  • [x] Can filter your datasource by scanning all fields.
  • [x] Can sort various types of data in your grid, smartly, detecting numbers and strings
  • [x] Width columns and height rows configurable or fall back to automatic proportion scaling depending on content
  • [x] Beautiful alternating colours for rows and column selections.
  • [x] Fully configurable header and footer labels including search view too.
  • [x] and beautiful clean presentation.

Data Source methods.

This is an optional data source implementation, you can also initialiase your SwiftDataTable with a static data set as shown in the Demo project so you can avoid conforming to the data source. But for those who want to show more dynamic content, use the following SwiftDataTableDataSource protocol.


public protocol SwiftDataTableDataSource: class {
    
    /// The number of columns to display
    func numberOfColumns(in: SwiftDataTable) -> Int
    
    /// Return the total number of rows that will be displayed in the table
    func numberOfRows(in: SwiftDataTable) -> Int
    
    /// Return the data for the given row
    func dataTable(_ dataTable: SwiftDataTable, dataForRowAt index: NSInteger) -> [DataTableValueType]
    
    /// The header title for the column position to be displayed
    func dataTable(_ dataTable: SwiftDataTable, headerTitleForColumnAt columnIndex: NSInteger) -> String
}

Delegate for maximum customisation

An optional delegate for further customisation. Default values will be used retrieved from the SwiftDataTableConfiguration file. This will can be overridden and passed into the SwiftDataTable constructor incase you wish not to use the delegate.


@objc public protocol SwiftDataTableDelegate: class {
    /// Specify custom heights for specific rows. A row height of 0 is valid and will be used.
    @objc optional func dataTable(_ dataTable: SwiftDataTable, heightForRowAt index: Int) -> CGFloat

    /// Specify custom widths for columns. This method once implemented overrides the automatic width calculation for remaining columns and therefor widths for all columns must be given. This behaviour may change so that custom widths on a single column basis can be given with the automatic width calculation behaviour applied for the remaining columns.
    @objc optional func dataTable(_ dataTable: SwiftDataTable, widthForColumnAt index: Int) -> CGFloat
    
    /// Column Width scaling. If set to true and the column's total width is smaller than the content size then the width of each column will be scaled proprtionately to fill the frame of the table. Otherwise an automatic calculated width size will be used by processing the data within each column.
    /// Defaults to true.
    @objc optional func shouldContentWidthScaleToFillFrame(in dataTable: SwiftDataTable) -> Bool
    
    /// Section Header floating. If set to true headers can float and remain in view during scroll. Otherwise if set to false the header will be fixed at the top and scroll off view along with the content.
    /// Defaults to true
    @objc optional func shouldSectionHeadersFloat(in dataTable: SwiftDataTable) -> Bool
    
    /// Section Footer floating. If set to true footers can float and remain in view during scroll. Otherwise if set to false the footer will be fixed at the top and scroll off view along with the content.
    /// Defaults to true.
    @objc optional func shouldSectionFootersFloat(in dataTable: SwiftDataTable) -> Bool
    
    
    /// Search View floating. If set to true the search view can float and remain in view during scroll. Otherwise if set to false the search view will be fixed at the top and scroll off view along with the content.
    //  Defaults to true.
    @objc optional func shouldSearchHeaderFloat(in dataTable: SwiftDataTable) -> Bool
    
    /// Disable search view. Hide search view. Defaults to true.
    @objc optional func shouldShowSearchSection(in dataTable: SwiftDataTable) -> Bool
    
    /// The height of the section footer. Defaults to 44.
    @objc optional func heightForSectionFooter(in dataTable: SwiftDataTable) -> CGFloat
    
    /// The height of the section header. Defaults to 44.
    @objc optional func heightForSectionHeader(in dataTable: SwiftDataTable) -> CGFloat
    
    /// The height of the search view. Defaults to 44.
    @objc optional func heightForSearchView(in dataTable: SwiftDataTable) -> CGFloat
    
    /// Height of the inter row spacing. Defaults to 1.
    @objc optional func heightOfInterRowSpacing(in dataTable: SwiftDataTable) -> CGFloat
    
    /// Control the display of the vertical scroll bar. Defaults to true.
    @objc optional func shouldShowVerticalScrollBars(in dataTable: SwiftDataTable) -> Bool
    
    /// Control the display of the horizontal scroll bar. Defaults to true.
    @objc optional func shouldShowHorizontalScrollBars(in dataTable: SwiftDataTable) -> Bool
    
    /// Control the background color for cells in rows intersecting with a column that's highlighted.
    @objc optional func dataTable(_ dataTable: SwiftDataTable, highlightedColorForRowIndex at: Int) -> UIColor
    
    /// Control the background color for an unhighlighted row.
    @objc optional func dataTable(_ dataTable: SwiftDataTable, unhighlightedColorForRowIndex at: Int) -> UIColor
}

Delegate customisation!

Now all these delegate methods are available for customising your swift data table. All these methods are optionals and default values will be provided. This is not a breaking change.

These same properties are also available in the DataTableConfiguration class allowing you to provide more defaults without requiring a delegate. The delegate is useful if you want to customise dynamically. I.e. specifying different row heights for different row indexes.

/// An optional delegate for further customisation. Default values will be used retrieved from the SwiftDataTableConfiguration file. This will can be overridden and passed into the SwiftDataTable constructor incase you wish not to use the delegate. 
@objc public protocol SwiftDataTableDelegate: class {
    /// Specify custom heights for specific rows. A row height of 0 is valid and will be used.
    ///
    /// - Parameters:
    ///   - dataTable: SwiftDataTable
    ///   - index: the index of the row to specify a custom height for.
    /// - Returns: the desired height for the given row index
    @objc optional func dataTable(_ dataTable: SwiftDataTable, heightForRowAt index: Int) -> CGFloat

    /// Specify custom widths for columns. This method once implemented overrides the automatic width calculation for remaining columns and therefor widths for all columns must be given. This behaviour may change so that custom widths on a single column basis can be given with the automatic width calculation behaviour applied for the remaining columns.
    /// - Parameters:
    ///   - dataTable: SwiftDataTable
    ///   - index: the index of the column to specify the width for
    /// - Returns: the desired width for the given column index
    @objc optional func dataTable(_ dataTable: SwiftDataTable, widthForColumnAt index: Int) -> CGFloat
    
    /// Column Width scaling. If set to true and the column's total width is smaller than the content size then the width of each column will be scaled proprtionately to fill the frame of the table. Otherwise an automatic calculated width size will be used by processing the data within each column.

0.6.11 - Jun 14, 2018

Summary:

  • Library upgraded to Swift 4,
  • Speed optimisations to return layout attributes for a given rect by a factor of 300 during scrolling!
  • A requested feature to enable the hiding of the footer labels
  • Example project updated to reflect the new visual footer hiding configuration.

Technical:

  • Example project storyboard removed in favour of a programmatic menu view controller. Makes it easier to demonstrate variations of the DataTableConfiguration object using a GenericDataTableViewController.
  • The swift language has been upgraded to swift 4 and runs on xcode 9.
  • The DataTableConfiguration object has a new property called shouldShowFooter with a default value of true. This property allows the user to override whether footers should be shown or not.
  • Refactors the layoutAttributesForRect method to use a binary search instead of filtering through all cached layouattributes. This sees a speed factory of 300 during scroll.
  • Aims to increase the prepare layout method in the SwiftDataTableLayout class by preventing unnecessary delegate calls for column widths.

0.5.3 - Apr 6, 2017

Implements Data Source with bug fix.

0.5.0 - Apr 6, 2017

Data source, here we are!! Simply implement the DataTableDataSource protocol and then call the reload method on the data table, and all the views will be initialised for you 👍

0.4.0 - Mar 17, 2017

🔎 🔎 Implements a Search Bar for data filtering! 🔎 🔎

Summary

A search bar is automatically added to all data tables to allow the user to filter through the loaded data set without changing any code.

Technicals

  • Swift Data Tables will automatically add a search bar to the data grid.
  • The search will find occurrences in every single data item, efficiently.
  • A row will be returned in the filtering process if even one of it's data items contain the needle.
  • The default filtering algorithm uses a contains matching expression.
