Introduction

Welcome to the documentation for btinfinitescrollview. This library provides a convenient way to implement infinite scrolling in your iOS app. Infinite scrolling allows users to continuously load content as they scroll, providing a seamless browsing experience.

Getting Started

To get started with btinfinitescrollview, follow the steps below:

Step 1: Installation

To install btinfinitescrollview, you can use CocoaPods. Simply add the following line to your Podfile:


pod 'btinfinitescrollview'

Step 2: Import

After installing, import btinfinitescrollview into your project using the following import statement:


import btinfinitescrollview

Step 3: Initialize and Configure

To use btinfinitescrollview, you need to initialize and configure it in your view controller.

First, create an instance of BtInfiniteScrollView by providing the frame for the scroll view. For example:


let infiniteScrollView = BtInfiniteScrollView(frame: CGRect(x: 0, y: 0, width: view.frame.width, height: view.frame.height))

Next, configure the content to be displayed in BtInfiniteScrollView. This is typically done by creating and configuring a UICollectionViewCell subclass that will represent each item in your infinite scroll view. You can set the delegate and datasource for the infinite scroll view to your view controller, and implement the necessary methods to provide content. For example:


class InfiniteScrollViewController: UIViewController, BtInfiniteScrollViewDelegate, BtInfiniteScrollViewDataSource {
// ...

Implement the necessary methods of the BtInfiniteScrollViewDelegate and BtInfiniteScrollViewDataSource protocols to provide the content for your infinite scroll view. For example:


func numberOfItems(in scrollView: BtInfiniteScrollView) -> Int {
return yourDataArray.count
}

func scrollView(_ scrollView: BtInfiniteScrollView, cellForItemAt index: Int) -> UICollectionViewCell {
let cell = scrollView.dequeueReusableCell(withReuseIdentifier: "yourReuseIdentifier", forIndex: index) as! YourCellClass
// Configure the cell with your data
return cell
}

Step 4: Add to View

Finally, add the BtInfiniteScrollView instance to your view hierarchy and make sure it has proper constraints. For example:


view.addSubview(infiniteScrollView)
infiniteScrollView.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
infiniteScrollView.topAnchor.constraint(equalTo: view.topAnchor),
infiniteScrollView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
infiniteScrollView.trailingAnchor.constraint(equalTo: view.trailingAnchor),
infiniteScrollView.bottomAnchor.constraint(equalTo: view.bottomAnchor)
])

Additional Configuration Options

BtInfiniteScrollView provides additional configuration options to customize its behavior and appearance. Some commonly used options include:

– Infinite Scrolling Direction

You can specify the direction of scrolling in your infinite scroll view. By default, it scrolls horizontally, but you can change it to vertical scrolling using the following property:


infiniteScrollView.scrollDirection = .vertical

– Pagination Size

You can set the number of items to load at a time when using infinite scrolling. This is referred to as pagination size. For example, to load 10 items at a time, use:


infiniteScrollView.paginationSize = 10

– Delegate Methods

BtInfiniteScrollViewDelegate provides several delegate methods to handle events and interactions with the infinite scroll view. Some commonly used methods include:

  • scrollViewDidScroll(_ scrollView: BtInfiniteScrollView): Called when the scroll view’s content offset changes.
  • didTapItem(at index: Int): Called when a cell is tapped in the infinite scroll view.

Conclusion

With btinfinitescrollview, you can easily implement infinite scrolling in your iOS app. By following the steps outlined in this documentation, you can provide a seamless browsing experience for your users. Explore the available configuration options and delegate methods to further customize your infinite scroll view.
