We'd love to see an update in this pod, any chances to make a swift 4 version?

I have tried many times ,but I can't see the shimmering effect when launch your project.
all the code is the same as when it was downloaded.
please give me a hand.

I see guys achieve this kind of effect. With a lot much less code.
I'm sorry~ i'm newbie, but just curious if this is possible?

I would love to use the shimmeringDirection property but it is not included in the 1.0.1 Cocoapod release.

Can you tag a new release and update the podspec?

I created a UIView. Added it as contentView of the shimmerView.

shimmerView is constrained to my TableViewCell.contentView -- left, right, top, bottom.
The UIView is then constrained to shimmerView -- left, right, top, bottom.

[shimmerView setShimmering:YES]; then gives the error:

[LayoutConstraints] Unable to simultaneously satisfy constraints.
    Probably at least one of the constraints in the following list is one you don't want. 
    Try this: 
        (1) look at each constraint and try to figure out which you don't expect; 
        (2) find the code that added the unwanted constraint or constraints and fix it. 
(
    "<NSLayoutConstraint:0x170284150 V:|-(0)-[UIImageView:0x1008b6b90]   (active, names: '|':UITableViewCellContentView:0x1008b1f10 )>",
    "<NSLayoutConstraint:0x1702841f0 UIImageView:0x1008b6b90.height == 175   (active)>",
    "<NSLayoutConstraint:0x170284380 V:[UIImageView:0x1008b6b90]-(0)-[FBShimmeringView:0x1008b4de0]   (active)>",
    "<NSLayoutConstraint:0x1702843d0 FBShimmeringView:0x1008b4de0.bottom == UITableViewCellContentView:0x1008b1f10.bottom   (active)>",
    "<NSLayoutConstraint:0x17409ab80 'UIView-Encapsulated-Layout-Height' UITableViewCellContentView:0x1008b1f10.height == 43.5   (active)>"
)

If I go to FBShimmeringLayer layoutSubViews and comment out:

_contentLayer.anchorPoint = CGPointMake(0.5, 0.5);
  _contentLayer.bounds = r;
  _contentLayer.position = CGPointMake(CGRectGetMidX(r), CGRectGetMidY(r));

the errors go away but Shimmering no longer works.

In this Pod i can't make diagonal animation

When working with AutoLayout (programmatically), the FBShimmerView is not created with initWithFrame, but just by init. This gives a shimmering speed issue. (Shimmering is way to fast.)

I created a gist to demonstrate the issue: https://gist.github.com/MichMich/9535985

e.g. Shimmer from top-to-bottom, bottom-to-top, as well as right-to-left.

Implemented inside a collection view cell
cell.shimmerDataView.contentView = loadingView

Getting the following crash on 'Crashlytics'

Ok, I’m surely missing something, but the fact that FBShimmeringLayer can’t simply be used with +layerClass and give whatever view the shimmering effect really bugs me.

Why is there the need for a contentLayer to limit the effect? Shouldn’t be simply self.mask = _maskLayer instead?

I tried this approach and worked perfectly…

(please keep in mind I just moved to Obj-C)

I was see such code in FBShimmeringLayer.m

UIKIT_EXTERN float UIAnimationDragCoefficient(void); 

I'm not so clear about the UIKIT_EXTERN.

please give your comments~thx!

Hey,

I've just released an Android version of that library. But reading your part regarding licensing and patents,

Shimmer is BSD-licensed. We also provide an additional patent grant.

I was wondering if there's any potential problem with me releasing the android version:

https://github.com/RomainPiel/Shimmer-android

Thanks!

Whether to support IB?

i tester in ios6 shimmer not display label in example code.

The Java library has an option for angle, but not the iOS one. I'm not sure how to get started, anyone has an idea on what's required to support this?

Android Native code is also available on GitHub
https://github.com/facebook/shimmer-android

Hello,
Thanks for the great source, it works like a charm.
Or I have a litte problem: this library support arc?

Jack

I wonder what happened with this repo?
I was going to use for my current app but it looks like it hasn't been update in a while.

Hey,

it is possible to set the Shimmer on a UIButton? I tried it already and it is not working. How can I modifier the lib for this feature?

ps: thanks for this awesome lib!!

    FBShimmeringView *shimmeringView = [[FBShimmeringView alloc] initWithFrame:self.view.bounds];
    [self.view addSubview:shimmeringView];

    shimmeringView.contentView = self.loginBt.titleLabel;

    // Start shimmering.
    shimmeringView.shimmering = YES;

I added the button via storyboard (weak, nonatomic)

Is there an way I can change the Shimmering direction.
Current default animation is from Left to Right.
What can I do to make it from Right to Left.

i use it in ios5.1, and it words fine,and i havn't find any apis need ios6 or later.so who can tell me why

The CocoaPod doesn't appear to have the update that includes being able to set a FBShimmerDirection.

warning info:
Assigning to 'id<CALayerDelegate> _Nullable' from incompatible type 'FBShimmeringLayer *const __strong'

- (void)_createMaskIfNeeded
{
  if (_shimmering && !_maskLayer) {
    _maskLayer = [FBShimmeringMaskLayer layer];
    _maskLayer.delegate = self;     // -> warning here ...
    _contentLayer.mask = _maskLayer;
    [self _updateMaskColors];
    [self _updateMaskLayout];
  }
}

With the help of the engineers who wrote Google's EarlGrey testing framework, we found that including

[UIApplication sharedApplication].keyWindow.layer.speed = 100;

CAAnimations freeze and crash the app. The shimmering view freezes when it starts to shimmer, and isn't able to be dismissed.

The last tagged version is from Febr 2014 (1.0.2) while the last commit is from 12 days ago !
This gives the false first impression that the project is dead, while it isn't.

Unfortunately also, if you add pod 'Shimmer' to your Podfile, CocoaPods will grab by default this 2014 version, which has bugs wrt Autolayout, Simulator and 64bits, that are now fixed in trunk.

Workaround: edit your Podfile like so: pod 'Shimmer', :git => 'https://github.com/facebook/Shimmer.git', :commit => '3589bd7ca0d122fe06792868485d79c622a3f47d'

When I try to compile Logo-iOS example project I see this error, what I'm doing wrong?

Trying to get Shimmer to work in my Swift project using a bridging header. When I try to implement a FBShimmeringView object in my controller, the linker throws this error:

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_FBShimmeringView", referenced from:
      type metadata accessor for __ObjC.FBShimmeringView in FeaturedViewController.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Am I correct in assuming this framework is incompatible with the latest iPhone 64-bit processors, or am I missing something here?

seems that fadeOutWithCompletion block doesn't work, only fadeout without block.
Thanks.

There is functionality in the current master branch not available in the latest CocoaPod, which was last updated December 2014. In the interest of saving other people headaches (too late to salvage mine), please keep the CocoaPod updated. Thanks!

I removed fadeLayer property of FBShimmeringMaskLayer, and commented out all the code related to this property. Everything still works fine. So my questions :

1. What's the purpose of fadeLayer ?
2. Since FBShimmeringMaskLayer is used as a mask layer, only alpha channel will be used. And fadeLayer is a sublayer of it, how does it affect anything here ? I tried to change the background colour of fadeLayer to various colours with various alpha values, but it doesn't have any effect.

There is a bug in facebook in chat, there is a chat panel in right side of facebook page, when there are lots of people are online and that time, if we scroll the scroll bar, then last user are not showing properly.

see the attachment..

At the moment the shimmer takes the colour from the object its shimmering, it would be nice if you could specify a colour for the shimmer to be.
An example, a white label, could have a gold shimmer.
I hope that makes sense.

Thanks
Andrew.

When compiling with -Wshadow, you get a warning

Hey there,

It seems like Shimmer doesn't work well with UIStackViews.

Here's what it's supposed to look like (this is without Shimmer added): https://abload.de/img/simulatorscreenshot15hokh1.png

Here's a screenshot of what happens when I add the Shimmer effect to the small grey view at the bottom: https://abload.de/img/simulatorscreenshot15x1kkz.png

The view hierarchy itself is very simple.

Cell View (grey coloured)
--UIStackView (white coloured)
----View (pink coloured)
----View (grey coloured)

I've got another similar view in my project which doesn't use a UIStackView and it works fine there (except from the fact that it's messed up when I rotate the device, but that's a different issue).

/Users/****/Downloads/Shimmer-master/Examples/Logo-iOS/ViewController.m:11:9: 'FBShimmering/FBShimmeringView.h' file not found

Like the title says, this is from a fresh build off master

What abouta react-native package for Shimmer?

Is there anyway I can specify if the shimmer happens from right to left or left to right?

Thanks!

I created a view(shimmerView) and added a FBShimmerView onto it. Then I make my app do this loop:
Show the shimmerView, go to other views, go to shimmerView, go to other views...

Everything was normal except that something increased in the memory.
So I opened Instrument to see what happened. And it showed that instances of FBShimmeringLayer and FBShimmeringMaskLayer increased by one every tine a FBShimmerView is displayed. That means when a FBShimmerView is deallocated, the FBShimmeringLayer is persisted in the memory.
See the screenshot below:

For example,

shimmeringView.delayTime = 3.0;
// Start shimmering in 3 seconds.
shimmeringView.shimmering = YES;

This is used in my own project~ 🍺

If I'm using Auto Layout on an FBShimmeringView, it doesn't seem to work. It appears to work only when initialized with an explicit frame.

This may be a non-issue and a necessary requirement of the library, but I'm just wondering if there are workarounds. I would like to center a shimmering view, and using rects isn't a great experience.

Thanks!

If you have multiple shimmering views, you may want their animations to be synchronized.

All in the title (happened upon a build against the iOS 7.0 SDK in Xcode 5.0.2). Here's the affected code:

- (void)setShimmeringSpeed:(float)speed
{
  if (speed != _shimmeringSpeed) {
    _shimmeringSpeed = speed;
    [self _updateShimmering];
  }
}

speed

First, thanks for this Code. It's great and it really helped me.

Using Xcode 8, iOS 10 beta 2 and I started getting two warnings in FBShimmeringLayer.m

Line 287 and 400.

287: _maskLayer.delegate = self;
...
400: fadeInAnimation.delegate = self;

WARNING:
Assigning to 'id<CALayerDelegate> _Nullable' from incompatible type 'FBShimmeringLayer *const __strong'

Since I'm a SWIFT developer I'm not quite sure how to fix it myself. I thought I'd post here before trying to fix it incorrectly myself.

help in updating the pod to the latest swift version i.e. 4.0

I'm trying to get Shimmer on a programmatically added button. It's a QBFlatButton, userStateButton = [[QBFlatButton alloc] initWithFrame:CGRectMake((cellView.frame.size.width - (80 + 20)), (self.screenHeight/(cellCount * 4)), 80, ((self.screenHeight + (cellCount * cellCount))/(cellCount * 2)))];

When I turn Shimmer on, the entire bounds that I've set for the button start shimmering (no surprise there, thats what I set the bounds as) so it looks like theres a rectangle around the logout button
FBShimmeringView *shimmeringView = [[FBShimmeringView alloc] initWithFrame:userStateButton.bounds];

How would I get just the text of the button to shimmer? I've already tried making the frame of the shimmeringView the frame of the titleLabel (which it turns out is {{0, 0}, {0, 0}}

Any way to do this without adding it to the storyboard like issue #8
