The CPScrollView class is a subclass of UIScrollView that allows for easy management of multiple UIViews. It provides a solution for creating a paged, horizontally scrolling view with navigation control.
Installation
To install CPScrollView using CocoaPods, simply add the following line to your Podfile:
pod 'CPScrollView'
Then, run the following command:
pod install
Getting Started
To use CPScrollView, first import the module:
import CPScrollView
Initialize an instance of CPScrollView:
let scrollView = CPScrollView(frame: view.bounds)
Set the delegate if you want to be notified of scroll events:
scrollView.delegate = self
Add UIViews to the scroll view:
for i in 0..<3 {
let view = UIView(frame: CGRect(x: CGFloat(i) * view.bounds.width, y: 0, width: view.bounds.width, height: view.bounds.height))
// Customize the view
scrollView.addSubview(view)
}
Specify the number of pages:
scrollView.totalPages = 3
Enable paging:
scrollView.isPagingEnabled = true
Navigation Control
CPScrollView includes a navigation control that allows users to easily navigate between views. You can customize the appearance of the navigation control by setting the following properties:
- dotColor: The color of the navigation dots.
- selectedDotColor: The color of the currently selected dot.
- dotSize: The size of the navigation dots.
- dotSpacing: The spacing between navigation dots.
- showNavigationControl: A boolean flag to show/hide the navigation control.
You can access the navigation control through the navigationControl
property of CPScrollView.
scrollView.navigationControl.dotSize = CGSize(width: 10, height: 10)
scrollView.navigationControl.dotColor = .gray
scrollView.navigationControl.selectedDotColor = .blue
Scroll Events
You can use the scrollViewDidScroll(_:)
delegate method to detect scroll events. For example, you can update the navigation control when the user scrolls:
extension ViewController: CPScrollViewDelegate {
func scrollViewDidScroll(_ scrollView: UIScrollView) {
let currentPage = scrollView.currentPage
// Update navigation control
}
}
