KVStore

KVStore is a wrapper over sqlite to store and persist key value pairs.

Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

To integrate CardsStack into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!

target '<Your Target Name>' do
    pod 'KVStore', '1.3'
end

Then, run the following command:

$ pod install

Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate CardsStack into your Xcode project using Carthage, specify it in your Cartfile:

github "priteshrnandgaonkar/KVStore" == 1.5

Run carthage update to build the framework and drag the built CardsStack.framework into your Xcode project.

How to use?

Create an instance of type KVStoreManager. As the name suggest, its a store manager which manages data of the KVStore. It can be initialised as follows

do {
	let storeManager = try KVStoreManager(with: "TestKVPersistence")
}
catch (let error) {
	showAlert(withTitle: "Error", buttonTitle: "OK", message: error.localizedDescription, okAction: nil)
}

From the above code snippet, you can see that the init method for KVStoreManager is failable. The above initialisation may either fail in the execution of sqlite statements(which is highly unlikely) or the creation of database file.

This KVStoreManager has the following API’s which eases the storage and fetching of data from sqlite database

func insert<T: Hashable>(value: Data, for key: T) throws
func deleteValue<T: Hashable>(for key: T) throws
func update<T: Hashable>(value: Data, for key: T) throws
func getValue<T: Hashable>(for key: T) -> Data?
 

You can also access the value through subscript syntax, like as follows

let data = storeManager[key]

The method definitions are self explanatory as to what they perform. The important point is that the key which is passed as argument should be of type Hashable and the value would be stored as Data

You can checkout the example in the framework and play around with it. To get used to this library.
