To run the example project, clone the repo, and run
pod install from the Example directory first.
SwiftSpreadsheet is available through CocoaPods. To install it, simply add the following line to your Podfile:
A short introduction on how to get started:
The rows of the spreadsheet represent a section in the collection view, with columns being the respective items. The leftmost and the rightmost elements of the spreadsheet (
rightRowHeadline), as well as the topmost and the bottommost elements (
bottomColumnFooter) are represented as
UISupplementaryView, which — if needed — have to be registered with the respective identifiers of the provided enum
ViewKindType (refer to the example code).
The corners of the resulting spreadsheet are represented as
UIDecorationView which can be passed as
UINib or as
AnyClass upon initialization of the layout. To allow more flexibilty you have to pass the given nib or class via the
DecorationViewType enum. Its cases hold one of the respective types as associative value:
A short example:
//Register SupplementaryViews first, then initialize the layout with optional Nibs/Classes for the DecorationViews let layout = SpreadsheetLayout(delegate: self, topLeftDecorationViewType: .asNib(topLeftDecorationViewNib), topRightDecorationViewType: .asNib(topRightDecorationViewNib), bottomLeftDecorationViewType: .asClass(bottomLeftDecorationViewClass), bottomRightDecorationViewType: .asClass(bottomRightDecorationViewClass)) //Default is true, set false here if you do not want some of these sides to remain sticky layout.stickyLeftRowHeader = true layout.stickyRightRowHeader = true layout.stickyTopColumnHeader = true layout.stickyBottomColumnFooter = true self.collectionView.collectionViewLayout = layout
Implement the provided
SpreadsheetLayoutDelegate. The methods are straightforward. Simply pass
nil wherever you do not want supplementary views to be displayed (leftmost, rightmost, topmost and bottommost).
//On Layout: layout.resetLayoutCache() //Helper Method for collection view collectionView.reloadDataAndSpreadsheetLayout()
So in short:
- Register the respective objects of type
UISupplementaryViewyou want to use with the provided identifiers of the enum
- Create a
UINibobject for each
UIDecrationView(corner of the Spreadsheet) and pass it upon initialization of the layout.
- Initialize the layout with the provided convenience initializer and pass the delegate as well as the required decoration views.
- Implement the
- Set the content of your cells and the supplementary views in the data source methods of your collection view.
- Enjoy 😉
