I cannot install SwiftGif for swift3.

My Podfile is ..

pod 'SwiftGifOrigin', '~> 1.6'

But I get the following error.

Analyzing dependencies
[!] Unable to satisfy the following requirements:

- `SwiftGifOrigin (~> 1.6)` required by `Podfile`
- `SwiftGifOrigin (~> 1.6)` required by `Podfile`

None of your spec sources contain a spec satisfying the dependency: `SwiftGifOrigin (~> 1.6)`.

You have either:
 * out-of-date source repos which you can update with `pod repo update`.
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.

Note: as of CocoaPods 1.0, `pod repo update` does not happen on `pod install` by default.

I run pod repo update, but I get the same error again.

How can I use SwiftGif??

Now you can call SwiftGif only by knowing the gif files name: UIImage.gifWithName("jeremy")

or can call the old method if prefered: UIImage.gifWithData(imageData!)

let cfProperties = CGImageSourceCopyPropertiesAtIndex(source, index, nil) is giving an error = "Cannot invoke 'CGImageSourceCopyPropertiesAtIndex' with an argument list of type 'CGImageSourceRef,Uint,nil)'

Hey, @bahlo

Great framework here! Very useful for an app I'm working on. I'm using Carthage in my app and was unfortunately having a problem with integrating SwiftGif. Based on #48, it seems that others have also had similar problems with using Carthage to integrate SwiftGif.

Anyway, this PR should fix the issue. Feel free to test it out and merge if you like.

Hi Bahlo, I've just took a look on your library. Everything works amazingly, but I am in stuck with a problem. How to pause temporarily the gif? I want pause and resume it for some reason (like music play, pause...)

Thanks very much and wait for your reply.

Hello,

I've added Carthage support for this project I started using. I know it says "Carthage compatible" but it actually didn't provide a shared Framework scheme. This is the error you'd get if you tried using it:

$  carthage update
*** Fetching SwiftGif
*** Checking out SwiftGif at "v1.5.1"
*** xcodebuild output can be found in /var/folders/tk/cw93k7v928qf21kppt47d_380000gn/T/carthage-xcodebuild.QXYO0e.log
*** Skipped building SwiftGif due to the error:
Dependency "SwiftGif" has no shared framework schemes

If you believe this to be an error, please file an issue with the maintainers at https://github.com/bahlo/SwiftGif/issues/new

Here is what I've done:

• Moved the code from "SwiftGifCommon" into a dedicated "SwiftGif" folder and created the framework scheme
• Renamed the "SwiftGif" target into "SwiftGifDemo"
• I updated the path in the podspec as well and bumped the version number so you can tag / push

Hopefully the travis build should still pass. Let me know what you think about this :smile:

Hello,

When I pull the framework with a carthage update (github "bahlo/SwiftGif" ~> 1.6.1), I can import it normally with "import SwiftGif" but I can't access to any methods of it...

Am I doing wrong or it's a framework issue? Thank you.

Hi, trying to load invalid data as a GIF crashes this code with EXC_BAD_ACCESS. This is due to the unsafe code in delayForImageAtIndex(). Proper checks should be in place and the UIImage.gifWithData() should throw / return nil if invalid data was handed in.

As a quick hack, the following is how I made this 'work' (= not crash):

    class func delayForImageAtIndex(index: Int, source: CGImageSource!) -> Double {
        var delay = 0.1

        guard let cfProperties = CGImageSourceCopyPropertiesAtIndex(source, index, nil) as? NSDictionary,
            gifProperties = cfProperties[kCGImagePropertyGIFDictionary as NSString] as? NSDictionary else {
                return delay
        }

        var delayTime = gifProperties[kCGImagePropertyGIFUnclampedDelayTime as NSString]

        if delayTime?.doubleValue == 0.0 {
            delayTime = gifProperties[kCGImagePropertyGIFDelayTime as NSString]
        }

        if let delayTime = delayTime {
            delay = delayTime.doubleValue
        }

        if delay < 0.1 {
            delay = 0.1 // Make sure they're not too fast
        }

        return delay
    }

Also, building for the device, I get the linker error:

ld: framework not found SwiftGifOrigin for architecture arm64

• Matti

// jeremy.gif
var url = NSBundle.mainBundle().URLForResource("jeremy", withExtension: "gif")
var imageData = NSData(contentsOfURL: url)

// Returns an animated UIImage
UIImage.animatedImageWithData(imageData)

This uses too many lines to setup the gif. It could have been only:

 UIImage.withGifName("jeremy")

I might do this in the future when I have time

When running the tests in Xcode6-Beta5, they fail when trying to load the test gif:

let cfImageData = imageData! as CFDataRef

Throws fatal error: unexpectedly found nil while unwrapping an Optional value; this looks to be caused by

imageData = NSData(contentsOfURL: NSBundle.mainBundle().URLForResource("test", withExtension: "gif"))

Returning nil. I've tried various ways of loading images, but can't seem to get the resources to load (UIImage named etc all fail).

Thanks for the awesome library!

Hey,

Just wanted to know if you're planning to update it for Swift3 or if it's abandonned ! So I can look for another third party option ! It would be a shame, it's the more practical and the lightest one !

hi, i loaded success gif image into my attribute string, but it can not animate, it's hard to me to know the problem

let attachment = NSTextAttachment()
                                    attachment.image = UIImage.gif(url: getEmojiUrl(name: data.Data))
                                    attachment.bounds = CGRect(x: 0, y: ((UIFont.systemFont(ofSize: 16).capHeight) - 28).rounded() / 2, width: 28, height: 28)
                                    let replacement = NSAttributedString(attachment: attachment)
                                    attributedString.replaceCharacters(in: aMatch.range, with: replacement)

this is sample link i loaded https://devlink.vedax.ai/images/emotions/cry.gif

So in storyboard I have an imageView, did set its class as "GIFImageView". When running app, the error in title is displayed.

Library installed as pod pod 'SwiftGifOrigin', '~> 1.7.0'

I also did a global search in the project Pods folder, and there are no results for a word "GIFImageView" - the class is not found in the library.

This is what I see:

First of all, awesome extension!

I'm using SwiftGif to display animations along the UI, but with iOS 13 I found some of my animations are not displaying correctly on DarkMode, so I'd like to have trait variations as we have with UIColor:

static var customAccent: UIColor {
    if #available(iOS 13, *) {
        return UIColor { (traitCollection: UITraitCollection) -> UIColor in
            if traitCollection.userInterfaceStyle == .dark {
                return MaterialUI.orange300
            } else {
                return MaterialUI.orange600
            }
        }
    } else {
        return MaterialUI.orange600
    }
}

I can make something similar with UIImage using this code (below), but I cannot get it to work with the Gifs.

extension UIImage {
    /// Creates a dynamic image that supports displaying a different image asset when dark mode is active.
    static func dynamicImageWith(
        light makeLight: @autoclosure () -> UIImage,
        dark makeDark: @autoclosure () -> UIImage
    ) -> UIImage {
        let image = UITraitCollection(userInterfaceStyle: .light).makeImage(makeLight())

        image.imageAsset?.register(makeDark(), with: UITraitCollection(userInterfaceStyle: .dark))

        return image
    }
}

extension UITraitCollection {
    /// Creates the provided image with traits from the receiver.
    func makeImage(_ makeImage: @autoclosure () -> UIImage) -> UIImage {
        var image: UIImage!
        performAsCurrent {
            image = makeImage()
        }
        return image
    }
}

Anyone have any idea on how to solve the problem?
