PrefsMate

CI Status Version License Platform

PrefsMate provide an elegant way to generate UITableView using a property list file(plist file, in short). Also, you can configure actions with its support. Thanks to the Codable protocol in Swift 4, it makes the code perfect clean.

Features

  • Data Persistence
  • Switch Accessory
  • Select Action
  • Muilty Sections
  • Section Header / Footer
  • Demo Project
  • World Ready
  • More Custom Cells

Background

In our app, we usually need a UITableView in PrefsViewController(or perhaps named SettingsViewController, whatever). And the interface may just looks like this:

PrefsViewController

When implementing this kind of stuff, your inner voice must be this: "Writing this UI is fxxking tedious! Is there any help that I can ask for?"

And congrats! You have come to the right place :).

Usage

1. Prepare a plist file containing formatted data

Taking example of the image above, the formatted plist file looks like this:

plist structure

The meaning of each item property is as follows:

Property usage
title the text on the left
detailText the text on the right
hasDisclosure whether the cell has a disclosure accessory view
hasSwitch whether the cell has a switch
switchStatus the status of the switch control
selectActionName the name of select action(optional)
switchActionName the name of switch action(optional)

Don't be afraid of this long file. In fact you just need to do some clickable things. You could even copy and paste our plist source code first just for your convenience.

2. Create the table view and do the parsing job

let tableView = Mate.createPrefsTableView()

You can add the parsing code in viewDidLoad():

 do {
      try Mate.parseWithSource(self, plistUrl: pListUrl) {
        tableView.reloadData()
      }
    } catch {
        // Handle with the error
    }

3. If needed, let your view controller conform to PrefsSupportable protocol

If you have select and switch action to handle, PrefsSupportable protocol already considered for you.

public protocol PrefsSupportable {
    /// Return a bunch of switchableItems, including their behavior in SwitchableItemHandler.
    var switchableItems: [SwitchActionName: SwitchableItemHandler]? { get }
    
    /// Return a bunch of selectableItems, including their behavior in SelectableItemHandler.
    var selectableItems: [SelectActionName: SelectableItemHandler]? { get }
}

Taking the switch of night theme for example:

var switchableItems: [SwitchActionName : SwitchableItemHandler]? {
        return [
            "handleThemeMode": { isOn in
                print("Dark theme mode is \(isOn)")
            }
        ]
}
var selectableItems: [SelectActionName : SelectableItemHandler]? {
        return [
            “changeIcon”: { 
                print(“Handle change icon action here”)
            }
           ...
           ...
        ]
}

Then we are done! PrefsMate will do right things for you.

Keep in mind: the "handleThemeMode" String must be the same value of switchActionName in the plist file. Same on selectActionName.

In switch actions, PrefsMate already take care of the data persistence. So you don’t need to store the user preferences yourself.

You could refer to Example project for more detail.

Suggestions

  • Being familiar with plist file structure will help you a lot. Sometimes you can directly edit the plist file through "Open As Source Code".

  • If you have an issue, please don't hesitate. Just let me know :)
