Solvedlottie ios Use image resources in lottie-ios

Hi, I read your code in the 'LOTLayerView.m' file, there is a method called '- (void)_setImageForAsset' to load image resources in our app used in lottie animation. But in the method you use '+ (nullable UIImage *)imageNamed:(NSString *)name;' to load image, which means we can only load images in app's main bundle. Is there any way for us to load images in other bundle, or is it possible for us to load images from a specified directory, for example, the cache directory or the document directory. Looking forward to your reply.

Hi guys,

I think the best solution is AnimationImageProvider. Lottie has AnimationImageProvider. I am sharing sample code below.

    public init(with jsonName: String) {
        super.init(frame: .zero)
        let animation = Animation.named(jsonName, bundle: getBundle())
        let imageProvider = BundleImageProvider(bundle: getBundle(), searchPath: nil)
        animationView = AnimationView(animation: animation, imageProvider: imageProvider)
    }

Take care of yourself 🤘🏻

This issue is fixed in current version. Thanks a lot!!!
First keep in mind that the file directory is the same as the JSON file ruled. There is a key to describe this image file folder name: "u":"images/" So your resource file directory must be like this
YourFilePath/data.json
YourFilePath/images/img_0.png
YourFilePath/images/img_1.png
Then you can use this method to load you JSON file and lottie will search the images in the same folder automatically,
LOTAnimationView* lottieAnimation = [LOTAnimationView animationWithFilePath:YourFilePath];
