## Introduction
Welcome to the documentation for nkjpagerviewcontroller – a custom view controller that provides a paged scrolling behavior, similar to the built-in UIPageViewController.
## Installation
To install nkjpagerviewcontroller, you can use CocoaPods, Carthage, or manually add the source files to your project.
### CocoaPods
- Open your Podfile and add the following line:
- Save the file and run the following command in the terminal:
pod 'nkjpagerviewcontroller'
pod install
## Usage
To use nkjpagerviewcontroller in your project, follow the steps below:
### Step 1: Import the module
import nkjpagerviewcontroller
### Step 2: Set up the view controller
In your view controller, create an instance of nkjpagerviewcontroller and set the data source and delegate:
// Create an instance of nkjpagerviewcontroller
let pageViewController = NKJPagerViewController()
// Set the data source and delegate
pageViewController.dataSource = self
pageViewController.delegate = self
### Step 3: Implement the data source methods
Implement the required data source methods to provide the content for the pages:
func numberOfPages() -> Int {
// Return the total number of pages
}
func viewControllerForPage(at index: Int) -> UIViewController {
// Return the view controller for the given page index
}
### Step 4: Customize the appearance
You can customize the appearance of nkjpagerviewcontroller by changing the properties of its appearance delegate:
// Customize the appearance
pageViewController.appearance.delegate = self
// Implement the appearance delegate methods to customize the appearance
func fontForTab(at index: Int) -> UIFont {
// Return the font for the tab at the given index
}
func textColorForTab(at index: Int) -> UIColor {
// Return the text color for the tab at the given index
}
### Step 5: Add the view controller
Add the nkjpagerviewcontroller as a child view controller and add its view to your view hierarchy:
// Add the page view controller as a child view controller
addChildViewController(pageViewController)
view.addSubview(pageViewController.view)
pageViewController.didMove(toParentViewController: self)
// Customize the frame of the page view controller's view if needed
pageViewController.view.frame = CGRect(x: 0, y: 0, width: view.bounds.width, height: view.bounds.height - 100)
### Step 6: Set the initial page
To set the initial page, call the `setCurrentPage(at:animated:)` method:
// Set the initial page to the first page
pageViewController.setCurrentPage(at: 0, animated: false)
### Step 7: Respond to user interactions
You can respond to user interactions by implementing the delegate methods:
func didScrollToPage(at index: Int) {
// Called when the page is scrolled to the given index
}
func didSelectTab(at index: Int) {
// Called when a tab is selected
}
## Conclusion
Congratulations! You have successfully integrated nkjpagerviewcontroller in your project. Refer to the documentation for more information about additional functionality and customization options.
