I translate your swift source to objc.
https://github.com/mifanj/JElasticPullToRefresh
If ok I want to send it to bbs
you can contact me [email protected]
I'm waiting for Get the Green Light with you.
I'll not send it untill you answer me.

Steps to reproduce:

1. Fire pull to refresh
2. Quickly go to some detail view controller
3. Quickly go back

Effect:
Pull to refresh sometimes stays on screen in some kind of hung state (circle not animating, view half cut). Scrolling the view removes the glitch from screen immediately

Expected effect:
View controller should appear in normal state with pull to refresh either hidden or finishing the animation gracefully.

Any advice on that or is it a bug that needs to be fixed?

For some reason, the view is snapping underneath my navigation bar? I have used the demo code given in the ReadMe.

// Initialize tableView
let loadingView = DGElasticPullToRefreshLoadingViewCircle()
loadingView.tintColor = UIColor(red: 78/255.0, green: 221/255.0, blue: 200/255.0, alpha: 1.0)
tableView.dg_addPullToRefreshWithActionHandler({ [weak self] () -> Void in
    // Add your logic here
    // Do not forget to call dg_stopLoading() at the end 
    self?.tableView.dg_stopLoading()
}, loadingView: loadingView)
tableView.dg_setPullToRefreshFillColor(UIColor(red: 57/255.0, green: 67/255.0, blue: 89/255.0, alpha: 1.0))
tableView.dg_setPullToRefreshBackgroundColor(tableView.backgroundColor!)

hi
I'm on a server with a lot of data is an array. I want whenever I applied for twenty data show in table view can i use plugin ??

Hi, it is a beautiful refresh library, easy create in table
But it has a problem in Collection，can't drag to show ,but had run the function
scrollViewDidChangeContentOffset(dragging: false)

as below the code

 let loadingView = DGElasticPullToRefreshLoadingViewCircle()
        loadingView.tintColor = UIColor(red: 78/255.0, green: 221/255.0, blue: 200/255.0, alpha: 1.0)
        self.collectionView!.dg_addPullToRefreshWithActionHandler({ 
            DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + Double(Int64(1.5 * Double(NSEC_PER_SEC))) / Double(NSEC_PER_SEC), execute: {
                self.collectionView!.dg_stopLoading()
            })
        }, loadingView: loadingView)
        
        self.collectionView!.dg_setPullToRefreshFillColor(UIColor(red: 57/255.0, green: 67/255.0, blue: 89/255.0, alpha: 1.0))
     
        self.collectionView!.dg_setPullToRefreshBackgroundColor(self.collectionView!.backgroundColor!)

that was test in the demo example code
Thank you

When I add this to a tableview in loadView (or viewDidLoad) from a storyboard, the tableview disappears after pulling to refresh. The code is called in the action block, but the tableview no longer is shown. View Debugging doesn't show the tableview in the hierarchy.

Anyone else have this issue?

Version 7.1.1 (7B1005)

After refresh, UITableView's func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) isn't triggered by first tap.

I have a problem, A present B, B dismiss, but B was not destroyed.
I think Dg_removePullToRefresh should not be called in deinit,
Because only call Dg_removePullToRefresh，B will be destroyed。
I modified the dg_removePullToRefresh。
public func dg_removePullToRefresh() { self.pullToRefreshView?.disassociateDisplayLink() self.pullToRefreshView?.observing = false self.pullToRefreshView?.removeFromSuperview() if self.pullToRefreshView != nil { self.pullToRefreshView = nil; } }
Google translation。

Would be useful for smaller screen sizes! Thank you for the awesome work :)

Hello,

The animation looks amazing but I can't get it to work. This is my code:

let loadingView = DGElasticPullToRefreshLoadingViewCircle()
loadingView.tintColor = UIColor.whiteColor()
tableView.dg_addPullToRefreshWithActionHandler({ [weak self] in
        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, Int64(1.5 * Double(NSEC_PER_SEC))), dispatch_get_main_queue(), {
            self?.tableView.dg_stopLoading()
        })
        }, loadingView: loadingView)
tableView.dg_setPullToRefreshFillColor(UIColor().menuDarkBlueColor())
tableView.dg_setPullToRefreshBackgroundColor(view.backgroundColor!)

Even if I remove the dispatch_after, as soon as I release the UIScrollView of the tableView, it completely disappears from the hierarchy. As you can see from these screenshots, the UITableView is removed from the hierarchy. Could this be due to a bug in your library?
The first screenshot is before reloading, the second one is while the pull to refresh animation is in course and the last is when the UIScrollView is released. You can find my source code here: https://github.com/BalestraPatrick/Tweetometer

Great job, is there any way to add text under the loading bar?
👍

I'm create my collectionView in loadView() method, and if my collection is empty i can't refresh him. What happened? :)

1. Run example app
2. Pull down to refresh
3. When state is animatingBounce rotate device/simulator

Actual result:
Activity indicator view has invalid position as well as controlPoints positions

Expected result:
I guess desired behaviour would be: finish/skip animatingBounce animation and go straight to loading state after rotation.

If a UITableView is set in a xib file and hooked unto the view controller via an IBOutlet, and it includes a tableHeaderView, it disappears after a pull to refresh.

This will be because the IBOutlet only has a weak reference to the UITableView and it is removed from the view heirachy temporarily

This is where is occurs:

public extension UIScrollView {
    func dg_stopScrollingAnimation() {
        if let superview = self.superview, let index = superview.subviews.indexOf({ $0 == self }) as Int! {
            let strongSelf = self
            //removeFromSuperview() // commenting out this line fixes the issue, but Im not sure if its needed for something else (changing the index?)
            superview.insertSubview(strongSelf, atIndex: index)
        }
    }
}

HI,

is it possibile to use DGElasticPullToRefresh into UICollectionView?

Thanks

I wrote a version for DGElasticPullToRefresh in Objective-C，but is imperfect , need your help
link :https://github.com/Mainstayz/DGElasticPullToRefresh 😊

Hey, I try to use it whit the storyboard, but when I pull down the table view, the tableView goes away.
Probably, because I use a tableView in Storyboard with constraints..
I don't know if you know what i meen :)

Hi,

I use storyboard but pull to refresh feature doesnt work properly. Circle animation not working, it stop immediately, and table view invisable.

My code here:

` //myTableView = UITableView(frame: ucretsizMaclarTableView.frame, style: .Plain) // This line caused error. (FlexibleWidh & Flexible Height, nil error)
myTableView.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]

    let loadingView = DGElasticPullToRefreshLoadingViewCircle()
    loadingView.tintColor = UIColor(red: 78/255.0, green: 221/255.0, blue: 200/255.0, alpha: 1.0)
    myTableView.dg_addPullToRefreshWithActionHandler({ [weak self] () -> Void in
        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, Int64(10 * Double(NSEC_PER_SEC))), dispatch_get_main_queue(), {
            self?.myTableView.dg_stopLoading()
        })
        }, loadingView: loadingView)
    myTableView.dg_setPullToRefreshFillColor(UIColor(red: 57/255.0, green: 67/255.0, blue: 89/255.0, alpha: 1.0))
    myTableView.dg_setPullToRefreshBackgroundColor(ucretsizMaclarTableView.backgroundColor!)`

DGElasticPullToRefreshLoadingViewCircle is not public and is not accessible when using DGE as a framework (CocoaPods).

Also, please consider renaming the classes to have shorter names. Swift has namespaces, so no need to obj-c style long names and prefixes.

Set auto start loading:

func dg_startLoading()

Where is it?
Thanks for ur work.

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'An instance 0x12e95fc00 of class UITableView was deallocated while key value observers were still registered with it. Current observation info: <NSKeyValueObservationInfo 0x12fc63f10> (

)'

already did the de init :(

Need to add

if (!self.observing) { return } 

in animateBounce() -> UIView.animateWithDuration -> completion:

or it will cause crash if the tableview is removed before it's called.

After pulling to refresh, a line appears under the Navigation bar until refresh has finished. Can you point our where in the library this might be occurring?

Im setting an image as the background self.navigationController!.navigationBar.setBackgroundImage(...)
And hiding the shadow with this self.navigationController!.navigationBar.shadowImage = UIImage()

The DGElasticPullToRefresh has a top mode refresh by default, how could we use it by the bottom mode?

That should be an easy fix.

I add a header for the table view and i got this problem as its appear below
i think its need more fixes

I ported to Objective-C from your tutorial. Hope that Objective-C guys love it 😃

Very good animation need iOS 9.0 min, any plan to iOS 8.0 supported ?

Hi,

A one-pixel line appears at the moment when when releasing - as can be seen in the attached image. It flashes for the briefest moment in time, but my app's contrast between the two colours is very high so it's quite obvious.

Is this in the library or could it be something weird in the way my UI is put together?

Support trigger load from code

Add a func to support simulate the drag and release action to trigger loading.

Hello,

I really want to use this library but I just want to know will it be compatible with UICollectionView?

Thank you! ;)

Hey !

I am trying to use your beautiful component but I am facing an error I can't solve. One of my view controller uses your DGElasticPullToRefreshwith its circle loading view. But when this view controller is deallocated I got the error :

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'An instance 0x7fd7d4343080 of class UIScrollViewPanGestureRecognizer was deallocated while key value observers were still registered with it

Any idea how to solve this ?

Thanks

Unfortunately the project doesn't build on 2.3

in dg_center:

> if usePresentationLayerIfPossible,
>             let presentationLayer = layer.presentationLayer() as? CALayer {
>             // Position can be used as a center, because anchorPoint is (0.5, 0.5)
>             return presentationLayer.position
>         }
>         return center

returns the following error:
Downcast from 'CALayer?' to 'CALayer' only unwraps optionals; did you mean to use '!'?

I am not sure why that downcast is there as layer.presentationlayer() seems to return a CALayer. If its unneeded then removing the downcast allows the project to build

It would be nice to have a method to fire the pull to refresh, something like objc dg_startLoading

Smaller devices (i.e. iPhones, especially 5s) in landscape barely give enough height to pull to refresh.

I changed the MinOffsetToPull constant to 50 to be suitable for all devices, but it might be preferable to have it dynamic.

What are your thoughts on this value?

When I pull to refresh and have section index enabled, on the pull and drag, the refreshView width gets cut off where the sectionIndex starts. On release, during the circle animation, the refreshView fills the entire width as it should.

I believe this is due to how Apple sets the active width of the scrollView when section Index is enabled, and since this library extends UIScrollView, it acts based on how Apple implements the scrollView behaviour.

Is there any currently known way around this? I'm sure a hacky solution exists, but just wondering if this is something that the library is capable of implementing

1. In the example project: set navigationController?.navigationBar.isTranslucent = true
2. Run app
3. Pulldown to refresh
4. Rotate device while refreshing (for any animatingBounce or loading states)

Actual result:
Refresh view disappears after table refresh and extra table content top inset is added so there is a empty space between nav bar and table content.

After rotation when dragging scroll down:

Expected result:
The same result when isTranslucent = false

Is there quick workaround for that?

DGElasticPullToRefresh is very good,can u support Carthage

Can i ？

When i pull to refresh, i see a faint line, probably the Nav Bar's border line. While on your display view example, there isn't any line separating the DGElasticPullToRefresh from the Navigation Bar. Thanks in advance :)

Any idea how I can get the white line between the refresh view and my "Volume XX - Issue XX" label ?

I installed DGElasticPullToRefresh using cocoapod. So I have version (1.0.3).
It does not build : I have 30 errors.

Is swift 3 support planned ?

Many thanks

makes the tableView go under the UINavigation bar.

Here is the code I used to set up the pull to refresh.

// Initialize tableView
let loadingView = DGElasticPullToRefreshLoadingViewCircle()
loadingView.tintColor = UIColor.whiteColor()
tableView.dg_addPullToRefreshWithActionHandler({ weak self -> Void in
self!.loadData()
}, loadingView: loadingView)
tableView.dg_setPullToRefreshFillColor(UIColor(red:0.000000, green:0.764706, blue:0.235294, alpha:1.0))
tableView.dg_setPullToRefreshBackgroundColor(tableView.backgroundColor!)

How to refresh automatically?

Is there a demo example of using this in an Obj-C project?
