A fantastic Physical animation library for swift

I want to design an animation by chaining several animations in a programmatically way.

I tried the following without success:

aView = aView.moveX(5.0).duration(2.0).completion({ do_something() }).then()
...
aView = aView.moveX(7.0).duration(1.0).completion({ do_something() }).then()

aView.animate()

How to achieve this?

I love Stellar. Animations with Swift like they should be. Thanks. but... Swift 3 branch seems to throw compile errors. Any plans on fixing this? Swift 3 officially out today. thanks.

Hi, For iOS and macOS projets it's will be great to make your component Carthage compatible

Take a look at these articles:

• Ruthlessly Simple Dependency Management with Carthage
• Carthage Tutorial: Getting Started
• Making Carthage-compatible Frameworks with Swift
• Swift Cross Platform Framework (section Configure targets for Carthage) 👍

On your README.md add on top and add section for the installation with Carthage.

Unless the library works differently it is ususally expected that a scale of 1 always return the identity matrix scalling column back.

However here with Stellar (and thanks for you great work btw), this not the case. A simple exemple with

myView.scaleXY(0.9,0.9).animate()
// later on: 
myView.scaleXY(1.0,1.0).animate()

shows that the scaling factor of 1.0 leave the scale of the view unchanged. And changing the second call to myView.scaleXY(1.1,1.1).animate() doesn't return the view to its original scale either (that, I have trouble understanding).

If you have any question regarding this, let me know :)

Previous function name conflicted with something ObjC.

Method 'autoreverses()' with Objective-C selector 'autoreverses' conflicts with getter for 'autoreverses' with the same Objective-C selector

Hi, I have just got an issue when I try to animate the appearance of a view by extending its width from 0 to full width, from left to right.

view.makeFrame(CGRect(origin: origin, size: CGSize(width: 0, height: view.bounds.height))).makeAlpha(1).duration(0).then()
            .makeFrame(CGRect(origin: origin, size: CGSize(width: width, height: view.bounds.height))).duration(1).animate()

The view is expected to extend from the origin of the view.

            |                                                   |               
            |----->-------------->-----------------------------
            |                                                   |  
            |                                                   |  
            |                                                   | 

(view left border) (view right border)

However, it did extend from the center of the view.

            |                                                   |               
            |                           ---->------------->---------------------------
            |                                                   |  
            |                                                   |  
            |                                                   |  

In the storyboard, autolayout of this view is set as having 0 padding to the left border of the container.

Hi,

Seems that makeAlpha is not working, or maybe I'm doing something wrong. Can you add an example of how to use it on the demo view controllers?

Thanks

I've noticed there's a podspec file available but some for strange reason I can't find the repo on CocoaPods.

pod 'Stellar'

Returns a Unable to find a specification for Stellar error.

Although downloading straight from the source works.

pod 'Stellar', :git=>'https://github.com/AugustRush/Stellar.git'

This pull request corrects the spelling of CocoaPods 🤓 https://github.com/CocoaPods/shared_resources/tree/master/media

One day I’ll make a bot that looks through the READMEs of all Pods, looks to see if it uses “Cocoapods” and PRs “CocoaPods” :D

For months now I have problem using Stellar with Carthage. I have to ways to solve the problems: 1/ by "manually" building Stellar framework after changing stuff in Xcode project or 2/ by adding sources to my project. But as for now the last option does not work because the code imported using Carthage is not the last one on GitHub...

So there is definitely something wrong with Carthage.

With 0.66 this exception is thrown on very basic animation:

myView.makeAlpha(0.0)
      .duration(aDuration)
      .autoreverses()
      .repeatCount(someRepetitions)
      .completion {
            // Some statements
              myView.removeFromSuperview()
            }
      .animate()

Let's say it's a find of flash.

I tried other animation like makeSizeor makeColor but same behavior.

This flash portion of code is called several times on a sequence basis. On the first call everything is fine. The exception is raises on the second call.
Between these two calls of flash there is an animation using CATransaction. On the completion block of this animation the second call of flash is then made.

CATransaction.begin()
CATransaction.setCompletionBlock({
      // call to flash animations
})

...

CATransaction.commit()

This error came after I decided to use CATransaction to use it's completion block.

Hi,

Interesting library!

Latest release here is 0.66, while on pods you can only find 0.61. Any reason to keep it that way? Could you update it there too? So we don't need to point this specific branch.

Thank you, H.

Using makeAlpha of 0.66 generates the Unsupport this animation type! (btw, Unsupport is not word ... Do not support this animation type! is better)

Reverting back to 0.65 fixed the issue by using the following in the Podfile pod 'Stellar', :git => 'https://github.com/AugustRush/Stellar', :commit => '5249167900b1eb136ce71543af7817a9fa5535cb'

I want to use Stellar with my project but I have this Value of type 'UIView' has no member error in my very first attempt to use Stellar on an UIView.

I use Carthage to install Stellar the same way as other libraries. It's like Stellar is not "installed". Installation using Stellar 0.65 is OK, and the usual Carthage installation has been followed. Then, I used the direct inclusion of Sourcesdirectory and everything is fine.

I have clean project. This is a weird behavior... Any idea? Is there special configuration for Carthage command?
