## Introduction
DMPagerViewController is a versatile library that allows developers to easily implement a paginated view controller in iOS applications. It provides a user-friendly way to navigate through multiple view controllers using swipe gestures.
## Installation
There are two ways to add DMPagerViewController to your project:
### Cocoapods Installation
To install DMPagerViewController using Cocoapods, add the following line to your Podfile:
“`xml
pod ‘DMPagerViewController’
“`
Then, run the following command in your terminal:
“`
$ pod install
“`
### Manual Installation
If you prefer to manually add DMPagerViewController to your project, follow these steps:
1. Download the latest version of DMPagerViewController from the [official Github repository](https://github.com/DominicMDev/dm-pagerviewcontroller).
2. Drag and drop the **DMPagerViewController** folder into your Xcode project.
3. Make sure to select “Copy items if needed” and choose the appropriate target.
## Getting Started
### Importing
To use DMPagerViewController, import it in the view controller where you want to implement the paginated view:
“`swift
import DMPagerViewController
“`
### Creating a Pager View
To create a pager view, instantiate an instance of `DMPagerViewController` and set its delegate:
“`swift
let pagerViewController = DMPagerViewController()
pagerViewController.delegate = self
“`
## Implementing the Delegate Protocol
DMPagerViewController provides a delegate protocol for handling view controllers and customizing the appearance. Adopt the `DMPagerViewControllerDelegate` protocol in your view controller:
“`swift
class MyViewController: UIViewController, DMPagerViewControllerDelegate {
//…
}
“`
### Providing View Controllers
Implement the following delegate method to provide the view controllers to be displayed in the pager view:
“`swift
func viewControllers(for pagerViewController: DMPagerViewController) -> [UIViewController] {
// Return an array of your desired view controllers
}
“`
### Customizing Appearance
Implement the following delegate methods to customize the appearance of your pager view:
“`swift
func title(for pagerViewController: DMPagerViewController, at index: Int) -> String {
// Return the title for each tab item at the specified index
}
func backgroundColor(for pagerViewController: DMPagerViewController) -> UIColor {
// Return the background color for the pager view
}
func indicatorColor(for pagerViewController: DMPagerViewController) -> UIColor {
// Return the color for the page indicator
}
func textColor(for pagerViewController: DMPagerViewController) -> UIColor {
// Return the text color for tab items and page indicator labels
}
“`
## Additional Configuration
### Changing the Current Page
To programmatically change the current page, call the `setCurrentPage(_:animated:)` method on your `DMPagerViewController` instance:
“`swift
pagerViewController.setCurrentPage(3, animated: true)
“`
## Conclusion
Using DMPagerViewController, you can easily create a paginated view controller in your iOS application, providing an intuitive way for users to navigate between multiple view controllers. With its delegate protocol, you can further customize its appearance to match your app’s design.
