Usage
Basic Implementation
To add pull-to-refresh functionality to your UIScrollView or UITableView, follow these steps:
1. Import the FCXRefresh module in your Swift file:
import FCXRefresh
2. Create an instance of FCXRefreshHeader or FCXRefreshAutoFooter:
// Example for UIScrollView
let header = FCXRefreshHeader(scrollView: scrollView)
// Example for UITableView
let footer = FCXRefreshAutoFooter(scrollView: tableView)
3. Customize the appearance and behavior of the refresh control (optional):
// Set custom colors
header.normalColor = UIColor.gray
header.highlightColor = UIColor.red
// Customize the text
header.titleText = "Pull to refresh"
header.refreshingText = "Refreshing..."
header.completeText = "Refresh completed"
// Set additional properties
header.isAutoStopRefresh = true
header.refreshingBlock = {
// Handle refresh action here
}
4. Add the refresh control to the UIScrollView or UITableView:
// Example for UIScrollView
scrollView.addFCXRefreshHeader(header)
// Example for UITableView
tableView.addFCXRefreshFooter(footer)
Advanced Techniques
FCXRefresh offers additional features and customization options:
1. Refresh Event Blocks
You can execute custom code blocks when a refresh event occurs:
header.refreshingBlock = {
// Perform custom refresh action
}
2. Refresh Completion
You can control when the refresh process is completed:
// Manually complete the refresh
header.endRefresh()
// Auto-complete the refresh after a certain delay
header.endRefresh(delay: 1.5)
3. Customizing Animations
You can customize the animations for pull-to-refresh and loading:
// Customize the pull-to-refresh animation
header.pullAnimationImage = UIImage(named: "pull_image")
// Customize the loading animation
header.loadingAnimationImages = [
UIImage(named: "loading_1"),
UIImage(named: "loading_2"),
UIImage(named: "loading_3")
]
4. Disable Auto Stop Refresh
You can disable automatic stopping of the refreshing state:
header.isAutoStopRefresh = false
