ICSPullToRefresh-Swift

ICSPullToRefresh-Swift is a Swift version of SVPullToRefresh, providing PullToRefresh && InfiniteScrolling features for UIScrollView

Installation

Embedded frameworks require a minimum deployment target of iOS 8.

CocoaPods

CocoaPods (>= 0.36) adds supports for Swift and embedded frameworks.

Add pod 'ICSPullToRefresh' to your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!

pod 'ICSPullToRefresh', '~> 0.6'

Carthage

To integrate ICSPullToRefresh into your Xcode project using Carthage, specify it in your Cartfile:

github "iCodesign/ICSPullToRefresh" >= 0.6

Manually

You can also integrate ICSPullToRefresh directly with souce code. Clone the repo and copy ICSPullToRefresh.swift and ICSInfiniteScrolling.swift to your project.

Usage

PullToRefresh

UIScrollView.addPullToRefreshHandler(() -> ())

Start/Stop animating:

UIScrollView.pullToRefreshView?.startAnimating()
UIScrollView.pullToRefreshView?.stopAnimating()

Trigger manually:

UIScrollView.triggerPullToRefresh()

Hide pulltorefresh:

UIScrollView.setShowsPullToRefresh(Bool)

Since after iOS7, iOS brings automaticallyAdjustsScrollViewInsets to UISrollView embedded in a UINavigationController or UITabBarController which changes contentInset of UISrollView between viewDidLoad nad viewDidAppear, so you have to put the addPullToRefreshHandler in or after viewDidAppear

Example:

tableView.addPullToRefreshHandler {
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), { [weak self] () -> Void in
        // do something in the background
        dispatch_async(dispatch_get_main_queue(), { () -> Void in
            self?.tableView.pullToRefreshView?.stopAnimating()
        })
    })
}

InfiniteScrolling

UIScrollView.addInfiniteScrollingWithHandler(() -> ())

Start/Stop animating:

UIScrollView.infiniteScrollingView?.startAnimating()
UIScrollView.infiniteScrollingView?.stopAnimating()

Trigger manually:

UIScrollView.triggerInfiniteScrolling()

Hide infiniteScrolling:

UIScrollView.setShowsInfiniteScrolling(Bool)

Since after iOS7, iOS brings automaticallyAdjustsScrollViewInsets to UISrollView embedded in a UINavigationController or UITabBarController which changes contentInset of UISrollView between viewDidLoad nad viewDidAppear, so you have to put the addInfiniteScrollingWithHandler in or after viewDidAppear

Example:

tableView.addInfiniteScrollingWithActionHandler {
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), { [weak self] () -> Void in
        // do something in the background
        dispatch_async(dispatch_get_main_queue(), { [unowned self] in
            self?.tableView.reloadData()
            self?.tableView.infiniteScrollingView?.stopAnimating()
        })
    })
}
