TableSchemer is a framework for building static interactive table views. Interface Builder provides a great way to build out static table views, but not everyone uses interface builder, and adding interactivity to these table views is difficult. Writing interactive static table views traditionally is a tiresome task due to working with index paths, and having multiple delegate methods to handle configuration, sizing, and selection handling. They're also a huge pain to maintain when the need to reorder them comes as you need to update the index paths in all those locations.
Features
Closure-based Table Views
Build your table view using closures, and have all of your cell(s) logic in one place. Forget index path comparisons, and focus on writing your logic. Thanks to Generics in Swift you can just work with your cell type and not worry about casting.
Built-in Schemes
TableSchemer comes with a variety of powerful schemes already built-in. Included is a basic scheme (for when you just need to render one cell), a radio scheme (for when you need a single cell in a group of cells selected at once), an array scheme (for when you need a dynamic set of cells backed by specific objects), and an accordion scheme (for when you need one cell to expand into many for a collapsed selection). Check out how to use them here.
Extendable
You can easily create your own Schemes and add them into your tables. With a few method overrides you can start creating unique, intuitive controls for your users.
Getting Started
- Download TableSchemer and see it in action using the example app. See Sample Project for instructions on how to get the sample project running.
- Start building your own tables by installing it in your own app. See Using Table Schemer for more information on how to use Table Schemer.
Requirements
TableSchemer is built using Swift 5, so it requires that you use Xcode 10.2. It supports iOS 8.0+.
Usage
TableSchemer works by creating a TableScheme object and setting it as your UITableView's dataSource property. Here's an example of using it with a UITableViewController:
class MasterViewController: UITableViewController {
var tableScheme: TableScheme!
override func viewDidLoad() {
super.viewDidLoad()
createTableScheme()
tableView.rowHeight = 44.0
}
func createTableScheme() {
tableScheme = TableScheme(tableView: tableView) { builder in
builder.buildSchemeSet { builder in
builder.buildScheme { (scheme: BasicSchemeBuilder<UITableViewCell>) in
scheme.configurationHandler = { cell in
cell.textLabel?.text = "Tap here for an advanced example."
cell.accessoryType = .disclosureIndicator
}
// We're specifying weak self here because handlers are retained by the schemes. Without it, we'd have a retain cycle.
scheme.selectionHandler = { [weak self] cell, scheme in
let advancedController = AdvancedTableSchemeViewController(style: .grouped)
self?.navigationController?.pushViewController(advancedController, animated: true)
}
}
}
}
}
}
TableSchemer will set itself as the data source and delegate of the table view. If you need to be the delegate to the table view update it after creating the scheme. To use the built-in selection and height handling you need to be sure to forward those delegate methods to the tableScheme object. The signatures are the same as in UITableViewDelegate. Check out the Using Table Schemer page for more, and be sure to check out our sample app!
Sample Project
There is a sample project that demonstrates a number of ways to make use of TableSchemer. To run them, clone the repo and run the TableSchemerExamples target.
