Hello Lee,

I added code for load images from remote server to render dynamic lottie json animations in iOS from remote server.

Could you please review and commit on lottie frame work

[buba447]

Theres already code in the framework for that
https://github.com/airbnb/lottie-ios/blob/master/lottie-ios/Classes/PublicHeaders/LOTAnimationView.h#L38

@buba447 These do not support remote images resource rendering. Just support only JSON file resource.

If I'm right - (nonnull instancetype)initWithContentsOfURL:(nonnull NSURL *)url; does:
LOTComposition *laScene = [[LOTComposition alloc] initWithJSON:animationJSON withAssetBundle:[NSBundle mainBundle]];, so the assets are still loaded from the main bundle. Are you gonna add the feature somehow in future, or should I try to tailor it and make a PR? Thank you

Hi @premyslvlcek. Have you got any possible solution for loading the images directly from the URL? Any help is appreciated.

[kanakaraju043]

yes , i modified few methods in lottie library to get it work.

Thanks,
kanakaraju

Hey @bhavukjain1, feel free to check my fork of this library, which adds support for loading images from dictionary. The key in the dictionary is the name of the image in the lottie json, for example img_01.png. The code is not final, but it works, sorry if there are some bugs, I haven’t seen obj-c for long time. It doesn’t support loading from the url, but you can load the image from the remote url yourself and then put it into the dictionary. See method called: “(nonnull instancetype)animationFromJSON:(nullable NSDictionary *)animationJSON assets:(nullable NSDictionary *)assetsDictionary NS_SWIFT_NAME(init(json:assets:));”
