Simple static table views for iOS in Swift. Static's goal is to separate model data from presentation. `Row`s and `Section`s are your “view models” for your cells. You simply specify a cell class to use and that handles all of the presentation. See the [usage](#usage) section below for details.

## Installation



### Carthage



[Carthage](https://github.com/carthage/carthage) is the recommended way to install Static. Add the following to your Cartfile:



``` ruby

github "venmo/Static"

```



### CocoaPods



[CocoaPods](http://cocoapods.org) is a dependency manager for Cocoa projects. To install Static with CocoaPods:



Make sure CocoaPods is installed (Static requires version 0.37 or greater).



Update your Podfile to include the following:



```ruby

use_frameworks!

pod 'Static', git: 'https://github.com/venmo/Static'

```



Run `pod install`.



### Manual



For manual installation, it's recommended to add the project as a subproject to your project or workspace and adding the appropriate framework as a target dependency.



## Usage



An [example app](Example) is included demonstrating Static's functionality.



### Getting Started



To use Static, you need to define [`Row`s](Static/Row.swift) and [`Section`s](Static/Section.swift) to describe your data. Here's a simple example:



```swift

import Static



Section(rows: [

    Row(text: "Hello")

])

```



You can configure `Section`s and `Row`s for anything you want. Here's another example:



```swift

Section(header: "Money", rows: [

    Row(text: "Balance", detailText: "$12.00", accessory: .disclosureIndicator, selection: {

        // Show statement

    }),

    Row(text: "Transfer to Bank…", cellClass: ButtonCell.self, selection: {

        [unowned self] in

        let viewController = ViewController()

        self.presentViewController(viewController, animated: true, completion: nil)

    })

], footer: "Transfers usually arrive within 1-3 business days.")

```



Since this is Swift, we can provide instance methods instead of inline blocks for selections. This makes things really nice. You don't have to switch on index paths in a `tableView:didSelectRowAtIndexPath:` any more!



### Customizing Appearance



The `Row` never has access to the cell. This is by design. The `Row` shouldn't care about its appearance other than specifying what will handle it. In practice, this has been really nice. Our cells have one responsibility.



There are several custom cells provided:



* `Value1Cell` — This is the default cell. It's a plain `UITableViewCell` with the `.Value1` style.

* `Value2Cell` — Plain `UITableViewCell` with the `.Value2` style.

* `SubtitleCell` — Plain `UITableViewCell` with the `.Subtitle` style.

* `ButtonCell` — Plain `UITableViewCell` with the `.Default` style. The `textLabel`'s `textColor` is set to the cell's `tintColor`.



All of these conform to [`Cell`](Static/Cell.swift). The gist of the protocol is one method:



```swift

func configure(row row: Row)

```



This gets called by [`DataSource`](Static/DataSource.swift) (which we'll look at more in a minute) to set the row on the cell. There is a default implementation provided by the protocol that simply sets the `Row`'s `text` on the cell's `textLabel`, etc. If you need to do custom things, this is a great place to hook in.



`Row` also has a `context` property. You can put whatever you want in here that the cell needs to know. You should try to use this as sparingly as possible.



### Custom Row Accessories



`Row` has an `accessory` property that is an `Accessory` enum. This has cases for all of `UITableViewCellAccessoryType`. Here's a row with a checkmark:



```swift

Row(text: "Buy milk", accessory: .checkmark)

```



Easy enough. Some of the system accessory types are selectable (like that little *i* button with a circle around it). You can make those and handle the selection like this:



```swift

Row(text: "Sam Soffes", accessory: .detailButton({

  // Show info about this contact

}))

```



Again, you could use whatever function here. Instance methods are great for this.



There is an additional case called `.view` that takes a custom view. Here's a `Row` with a custom accessory view:



```swift

Row(text: "My Profile", accessory: .view(someEditButton))

```



### Custom Section Header & Footer Views



`Section` has properties for `header` and `footer`. These take a `Section.Extremity`. This is an enum with `Title` and `View` cases. `Extremity` is `StringLiteralConvertible` you can simply specify strings if you want titles like we did the [Getting Started](#getting-started) section.



For a custom view, you can simply specify the `View` case:



```swift

Section(header: .view(yourView))

```



The height returned to the table view will be the view's `bounds.height` so be sure it's already sized properly.



### Working with the Data Source



To hook up your `Section`s and `Row`s to a table view, simply initialize a `DataSource`:



```swift

let dataSource = DataSource()

dataSource.sections = [

    Section(rows: [

        Row(text: "Hello")

    ])

]

```



Now assign your table view:



```swift

dataSource.tableView = tableView

```



Easy as that! If you modify your data source later, it will automatically update the table view for you. It is important that you don't change the table view's `dataSource` or `delegate`. The `DataSource` needs to be those so it can handle events correctly. The purpose of `Static` is to abstract all of that away from you.



### Wrapping Up



There is a provided [`TableViewController`](Static/TableViewController.swift) that sets up a `DataSource` for you. Here's a short example:



```swift

class SomeViewController: TableViewController {

    override func viewDidLoad() {

        super.viewDidLoad()

        dataSource.sections = [

            Section(rows: [

                Row(text: "Hi")

            ]),

            // ...

        ]

    }

}

```



Enjoy.
