Pure Swift PullToRefresh, providing PullToRefresh && InfiniteScrolling features for UIScrollView

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()
        })
    })
}

icspulltorefresh.swift's Issues

Readme

infiniteScrollingView是否可以在接近底部的位置预先展示一个loading状态的indicator？

hello wanglei,

我发现目前的版本在下拉到尾部的时候给人的感觉不太友好，是否可以在接近尾部的时候预先加载一个loading状态的indicator？

另外顶部下拉的时候，如果在网速过快的时候是否可以人为的增加一点延迟时间，否则给人感觉是下拉无效，而且loading的菊花也不会转动（我不确定是不是我的网速太快了....）

谢谢~

Orientation Change Bug, see #9

See #9 for more detail

ActivityIndicator are showing before the scrolling

Xcode 7.1.1: error: reference to property 'scrollView' in closure requires explicit 'self.'

Hi
When I try to build your component Xcode 7.1.1 (7B1005) generate this error

ICSPullToRefresh.swift:172:13: error: reference to property 'scrollView' in closure requires explicit 'self.' to make capture semantics explicit
            scrollView?.contentInset = contentInset
            ^
            self.

I noticed that the last commit was march. Anyone has any experience with this pod with swift 3?

InfiniteScrolling

InfiniteScrolling Not showing correctly sometimes at loading state

Xcode 7 problem

Hi, there is a problem with the Xcode 7 GM and Swift 2

   public override func observeValueForKeyPath(keyPath: String?, ofObject object: AnyObject?, change: [String : AnyObject]?, context: UnsafeMutablePointer<Void>) {
    if keyPath == observeKeyContentOffset {
        srollViewDidScroll(change[NSKeyValueChangeNewKey]?.CGPointValue)
    } else if keyPath == observeKeyFrame {
        setNeedsLayout()
    }
}

the error is: Cannot subscript a value of type '[String : AnyObject]?' with an index of type 'String'

Custom UIActivityIndicatorView

Hi, Would be awesome if we could have custom UIActivityIndicatorView for the refresh control

Loading icon not center

offset loading icon not center, it's center only on iphone 6 PLUS

Full Functional Demo Project

Handler retain cycle

I recently ran into the issue that my view controller had a retain cycle in the pullToRefresh handler. I don't think that there needs something to be changed, but I do suggest that you add a [weak self] in your example as follows:

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

Carthage Support

Infinite scrolling does not working well

Hello,

Infinite scrolling is trigger when I just try to scroll tableview to see my last cell.
