## Introduction
Welcome to the documentation page for the NavigationMenuController library. This library provides a convenient and customizable way to implement navigation menus in your iOS application. Here, you will find detailed information on how to install, configure, and use the NavigationMenuController library effectively.
## Installation
### Prerequisites
Before installing the NavigationMenuController library, ensure that you have the following requirements:
#### Hardware
– Mac computer with Intel processor
– iOS device for testing (optional, but recommended)
#### Software
– Xcode IDE (Integrated Development Environment)
– Swift language knowledge
– CocoaPods dependency manager
### Installing the NavigationMenuController Library
To install the NavigationMenuController library, follow the steps below:
1. Open your project in Xcode.
2. Navigate to the desired directory using the terminal.
3. Run the following command to create a new Podfile:
“`ruby
$ pod init
“`
4. Open the Podfile using a text editor and add the following line in the appropriate target section:
“`ruby
pod ‘NavigationMenuController’
“`
5. Save the Podfile and run the following command:
“`ruby
$ pod install
“`
6. Close your Xcode project and open the newly created workspace file (`.xcworkspace`).
7. Import the NavigationMenuController module in your Swift files to start using it.
“`swift
import NavigationMenuController
“`
## Usage
### Creating a NavigationMenuController
To create a navigation menu in your application, you need to instantiate a `NavigationMenuController` object. Follow the steps below:
1. In your view controller, import the NavigationMenuController module by adding the following line at the top:
“`swift
import NavigationMenuController
“`
2. Create an instance of `NavigationMenuController` using the desired configuration options. For example:
“`swift
let menuController = NavigationMenuController(items: [“Home”, “About”, “Services”])
“`
The `items` parameter is an array of strings representing the menu items.
### Customizing the Navigation Menu
You can customize the appearance and behavior of the navigation menu using the following options:
#### Menu Item Styles
You can specify different styles for the menu items using the `itemStyle` property. For example:
“`swift
menuController.itemStyle = .underline(radius: 4, color: .blue)
“`
In this example, the menu items will be underlined with a blue color and a radius of 4.
#### Menu Item Selection Handler
You can provide a closure to handle menu item selection using the `onSelection` property. For example:
“`swift
menuController.onSelection = { index in
print(“Selected item at index: \(index)”)
}
“`
In this example, the closure will be called when a menu item is selected, and it will print the selected item’s index.
### Displaying the Navigation Menu
To display the navigation menu, follow the steps below:
1. Add the `menuController` instance as a child view controller of your desired view controller. For example:
“`swift
addChild(menuController)
“`
2. Add the menu controller’s view to your desired position in the view hierarchy. For example:
“`swift
view.addSubview(menuController.view)
menuController.view.frame = CGRect(x: 0, y: 100, width: view.frame.width, height: 60)
“`
In this example, the menu controller’s view is added 100 points below the top of the parent view and has a width equal to the parent’s width.
3. Call the `didMove(toParent:)` method to complete the setup. For example:
“`swift
menuController.didMove(toParent: self)
“`
