JGSettingsManager

An easy-to-use settings manager to define, access, and store NSUserDefaults the Swift way.

Screen Shot from Example:

Installation

• via Carthage: github "ziligy/JGSettingsManager"
• or copy JGSettingsManager folder to your project

Usage

• Declare storage items using JGUserDefault for each
• Select a SettingsCell UI component for each item
• Create Sections array to load into the Manager

import JGSettingsManager

struct UserDefaults {
    let mapType = JGUserDefault (key: "mapTypeIndex", defaultValue: "standard") // String
    let zoomLevel = JGUserDefault (key: "zoomLevel", defaultValue: 10) // Int
}

class SettingsTable: JGSettingsTableController, SettingsSectionsData {

    override func viewDidLoad() {
        super.viewDidLoad()
        self.tableSections = loadSectionsConfiguration()
    }

    internal func loadSectionsConfiguration() -> [Section] {

        let userDefaults = UserDefaults()

        let sections = [

            Section (
                header: "Map Type",
                footer: "",
                settingsCells: [
                    SegmentedControlTableCell(stringValue: userDefaults.mapType, segments: ["standard","satellite","hybrid"]),
                ],
                heightForFooter: 10.0
            ),

            Section (
                header: "Map Zoom Level",
                footer: "Initial zoom level for map",
                settingsCells: [
                    StepperTableCell(stepperData: userDefaults.zoomLevel, minimumValue: 1, maximumValue: 30)
                ]
            )]

        return sections
    }
}

• Add TableController to Storyboard

• Assign SettingsTable as Custom Controller

• select Table style: Grouped for nice formatting

• That's it!

• The JGSettingsManager will save the user's values in NSUserDefaults for persistent storage even when the app is closed.

Access Settings in App

• Use the JGUserDefault items

print(zoomLevel.value())

prints the last value from the settings table or the default
