0.8.1: Adds right-to-left (RTL) Data table layout direction support for RTL …

29 Aug 02:04

Summary:

  • You will now automatically truly support right-to-left (RTL) language users.

Technical:

  • Previously only the text within the data table would be flipped RTL for RTL languages but the content within the scrollview - such as columns - would remain in left-to-right. This release introduces the fix and ensures the layout direction is also along with the text giving a true RTL experience to RTL language users.

In practise

How do I opt in and ensure my users can benefit from this feature?

The package automatically enables this feature for you.

How can I manage this feature myself?

You can choose to opt out or opt in for certain data tables in two ways:

Via Delegate method

Simply adopt the SwiftDataTable's delegate method with the following signature:

    func shouldSupportRightToLeftInterfaceDirection() -> Bool {
        // and return true or false here. True will allow the data table to detect if a RTL language is being used and will flip the entire layout appropriately and display content correctly.
        // false will leave the layout direction and only flip the text which would happen regardless anyway without this feature.
        return true 
    }

Via Configuration

var configuration = DataTableConfiguration()
// The default is true
configuration.shouldSupportRightToLeftInterfaceDirection: Bool = false // set to false incase you don't want to use this feature

Fixed Columns are here! Freeze those columns!

Summary:

  • You can now have fixed columns on both left and right hand sides! It's as easy as either specifying the fixedColumns property in the configuration object, or by implementing the fixedColumns delegate method.

Technical:

  • Due to objective-c delegate requirements the type you return in the fixedColumns delegate method is a class instead of Swift's struct type.
  • Tests have been added to ensure the new DataTableFixedColumnType initialises as expected.
  • The leftColumn and rightColumn arguments in the initialiser are one-index based. That is they start at 1. This is to create a natural declaration of the fixed columns. For example, DataTableFixedColumnType.init(leftColumns: 2, rightColumns: 2) would fix the first 2 columns (from the left) and the last 2 columns (from the right).
  • As usual the delegate method will take priority. So the fixedColumns object will first be fetched from the delegate method and if it's not implemented it will fallback on the configuration object. So if you want the fixedColumn configuration value to be read then you need to make sure to omit the fixedColumns delegate method.

In practise

How to use the new Fixed columns feature!

Here's how you define which columns you want frozen, by using the all new DataTableFixedColumnType class, and using any of the initialisers like so

// Example 1 - freeze from the left
DataTableFixedColumnType(leftColumns: 1) // this will freeze the n number of columns from the left of the table. In this case column number 1 - the first columns. This is a one-index based system

// Example 2 .- freeze from the right
DataTableFixedColumnType(rightColumns: 1) // this will freeze n number of columns from the right of the table. In this case the last column. 

// Example 3 - multiple columns
DataTableFixedColumnType(leftColumns: 2, rightColumns1) // You can specify multiple columns to be frozen on both sides. In this case the first 2 columns and the last column.

You can implement fixed columns in your data table in two ways:

Via Delegate method

Simply adopt the SwiftDataTable's delegate method with the following signature:

@objc optional func fixedColumns(for dataTable: SwiftDataTable) -> DataTableFixedColumnType {
    // and return the object here
    return .init(leftColumn: 2) // freeze the first two columns
}

Via Configuration

var configuration = DataTableConfiguration()
configuration.fixedColumns = .init(leftColumns: 2, rightColumns: 1) // freeze both the first two columns, and the last column

Summary:

  • Library upgraded to Swift 5
  • Introduction of tests to reduce regression and make the library more bullet proof.
  • Sorting arrow colour can be customised now in the configuration object.
  • Fix: Using a specific initialiser would ignore DataTableConfiguration leading to custom configurations not being used.

Technical:

  • The swift language has been upgraded to swift 5
  • A test target has been added, with an initial tests to ensure initialisation with custom configuration works for a specific initialiser that would previously not initialise with the configuration object.
  • The SwiftDataTableConfiguration and DataTableColumnOrder models now conforms to Equatable
  • The sorting arrow icons now render as template mode enabling a custom colour.

Fixes a crash when datasource is empty and makes datasource rows public

Summary:

  • Fixes crash when datasource is empty
  • Demo project updated to show an empty state
  • rows property is now available allowing you to access the current datasource as it is - maintained by SwiftDataTable.
  • There's a new method which allows you to fetch the data value type for a given index path - see technical information for more details.

Technical:

  • There is a new method added allowing you to fetch a data value type for a given index path:
public func data(for indexPath: IndexPath) -> DataTableValueType

This method can be used as a convenience method or you can use the rows property to access the multi-dimensional array manually.

Going forwards the library will support Swift 4.2 support.
There's also a new did select and deselect delegate method:

    /// Fired when a cell is selected.
    ///
    /// - Parameters:
    ///   - dataTable: SwiftDataTable
    ///   - indexPath: the index path of the row selected
    @objc optional func didSelectItem(_ dataTable: SwiftDataTable, indexPath: IndexPath)

    /// Fired when a cell has been deselected
    ///
    /// - Parameters:
    ///   - dataTable: SwiftDataTable
    ///   - indexPath: the index path of the row deselected
    @objc optional func didDeselectItem(_ dataTable: SwiftDataTable, indexPath: IndexPath)

Delegate for customisation!

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.
    /// Defaults to true.
    ///
    /// - Parameter dataTable: SwiftDataTable
    /// - Returns: whether you wish to scale to fill the frame of the table
    @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.

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.
