Hello. It appears that if one wants this control working on iOS 5, the following code must be used instead:

self.refreshControl = (UIRefreshControl *)[[CKRefreshControl alloc] init];

If the normal [UIRefreshControl alloc] init] is used and if one runs iOS 5, the control doesn't seem to appear above the table view.

Steps to reproduce:

1. Used cocoapods to install CKRefreshControl

platform :ios, '5.0'
pod 'CKRefreshControl', '~> 1.0.0'

1. Opened the .xcworkspace that is generated by cocoapods
2. Used the following code for my UITableView (note that it works fine in iOS 6 of course):

#import <CKRefreshControl/CKRefreshControl.h>
...
self.refreshControl = [[UIRefreshControl alloc] init];
        [self.refreshControl addTarget:self
                                action:@selector(refresh)
                      forControlEvents:UIControlEventValueChanged];

1. The control doesn't appear in iOS 5 but appears in iOS 6

CKRefreshControl is a subproject of an SDK that is a subproject with the app

able to import using:

import "CKRefreshControl.h"

not able to import using:

import <CKRefreshControl/CKRefreshControl.h>

The strange thing is that I am able to import SDWebImage just fine (also a subproject of SDK) using:

import <SDWebImage/UIImageView+WebCache.h>

this problem only occurs when Archiving

any ideas as to why this is the case?

On ios 5.1 simulator, when refresh control is refreshing and the user scrolls down, the first section header stays in place, overlapping the rest of the content (which is scrolling) .

The section header apparently thinks its already at the top of the scrollview and thus remains stationary. I dont know how much can be done about this, since its a UITableView feature, but it works correctly on ios 6 with UIRefreshControl so perhaps it can be fixed by modifying CKRefreshControl.

I wont have time to look into this during the next 1-2 months, possibly never (sorry), so if someone knows how to fix it, feel free.

a setTintColor:nil message is passed to the refresh control after the storyboard view controller has loaded.

I know, it is meta issue, but there is no new line at the end of CKParagraphStyle.h

Adding an initial tag, and tagging subsequent versions, would allow for a .podspec to be created for this repo and could then be added to CocoaPods.

Is there a reason you have not implemented the ability to initialize CKRefreshControl from a storyboard?

Hi, first of all thanks for the work on this component, it's a really swell idea to bring parity to iOS5 and 6 apps.

I'm hitting a rendering issue using CKRefreshControl with a UITableView that uses an index. Whenever a CKRefreshControl is present interactions with the index control causes the index to "jump" out of place and then snap back in a very unpleasing way. The issue is not present in iOS 6 (where UIRefreshControl is used) and goes away when CKRefreshControl is not present in iOS 5.

I've captured the behavior occurring in the simulator in this short video: https://dl.dropbox.com/u/10239781/CKScrollIssue.mov

In the spirit of open source, I will attempt to debug this on my own, but wanted to post a note here to see if this is a known issue.

Tried to compile an app for a iPad one. CFRefreshCOntrol fails with

/Users/derekclarkson/projects/CashManagement/External/CKRefreshControl/CKRefreshControl/CKRefreshControl.m:497:2: error: Unsupported CP

1 error generated.

I deduced that the CPU macro being returned TARGET_CPU_ARM64 and by adding the following patch I was able to get it to run.

I'm not sure if this is correct because I think it needs some asm, but I don't have the knowledge to work it out.

Can this be looked at and patched please.

This version is not working using cocoa pods, it crashes on iOS 5.0. But if you download the project directly it works.
Tag 1.0.0 is different from Branch. CKParagraphStyle is missing, and there are changes in other files.

If I have a UITextField in one of the cells at the bottom of the UITableView (with CKRefreshControl) then the tableview doesn't scroll automatically to show the textfield as it should do.

Hello, first of all thanks for the work on this component!

I'm trying to use the component to refresh a UiTableView in a UIViewController, but i cannot make it work :-(

This is my code:

UIRefreshControl *refresh = [[UIRefreshControl alloc] init];
[refresh addTarget:self.TableView action:@selector(doRefresh:) forControlEvents:UIControlEventValueChanged];

The project compile successfully, but the control doesn´t work

can anyone help me, please?

I'm using Xcode 4.6.2 and adding CKRefreshControl 1.1.0 as a CocoaPod to my project that supports iOS 5 and up. When attempting to run on the iOS 5.1 (or 5.0) simulator, this message shows up in the console:

dyld: Symbol not found: OBJC_CLASS$_UIRefreshControl
Referenced from: /Users/jmedf/Library/Application Support/iPhone Simulator/5.1/Applications/4DA1DA57-47E6-4D77-B635-6ED600782758/MY_APP.app/MY_APP
Expected in: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.1.sdk/System/Library/Frameworks/UIKit.framework/UIKit

I followed the steps on the readme. The only difference is we are initializing this way:

self.refreshControl = [[UIRefreshControl alloc] init];
[self.refreshControl addTarget:self action:@selector(doRefresh:) forControlEvents:UIControlEventValueChanged];

Everything works as expected in iOS 6. I can only deduce that this class can't see CKRefreshControl. I'm importing with:

import "CKRefreshControl.h"

CKRefreshControl is a dependency of a static library

error is as follows:

Undefined symbols for architecture armv7s:
"OBJC_CLASS$_CKRefreshControl", referenced from:
objc-class-ref in libTGOSDK.a(TGOViewController.o)
ld: symbol(s) not found for architecture armv7s
clang: error: linker command failed with exit code 1 (use -v to see invocation)

was previously working with changes i made on bad pull request earlier ...

can be fixed by removing ONLY_ACTIVE_ARCH = YES; from Debug configuration

Hello,

Thank you very much for this addition, it is the perfect solution! I don't know if this is the best way to contact you, but I've just joined so it seemed to be the easiest way :)

I am having a small problem, I looked through the demo files and saw that libCKRefreshControl.a was added within the demo project but I could not find this file in the repository or the downloaded files?

Is this file created once the -ObjC linker flag is added? I was receiving EXC_BAD_ACCESS - then I realised I had not included the flag, so until then I will keep trying.

Craig

Using the UIRefreshControl directly in a storyboard triggers the following error in xCode5:

..../CKRefreshControl/RefreshControlDemo/en.lproj/MainStoryboard.storyboard: error: Class Unavailable: UIRefreshControl on iOS versions prior to 6.0

Adding the control programmatically still works fine.
But the Demo project on 1.1.1 has this error with the latest xCode 5.0

Hi,
I run the dome,but "Unsupported CPU" error.
Something wrong with it.
