How to trim down custom Skobbler offline map app s

问题:

I'm integrating Skobbler maps in my iOS app.

Right now, the app is 160Mb in size, which is way too much. But I notice that there are bunch of maps integrated already. I would like to erase all maps and let the user download the ones he would need.

Right now, when I include SKMaps.framework, there is SKMaps document in it, that's 95Mb in size.

Is there any way to make this document smaller or downloadable after initial app is downloaded.

I have to make my app as small as possible. Also, as I don't need maps of the entire world, Is there a way do download some file with US maps only (even better option to download only the states a user would need)

You could integrate only the desired packages. See how to deal with prebundled maps in this blog post: http://sdkblog.skobbler.com/creating-an-app-with-a-pre-bundled-map/

Also to minimize the size of the project you can do the following:

1. Remove all audio advices but en_us from SKAdvisorResources.bundle (Note: you can host & download the audio files on demand)
2. Remove Outdoorstyle and Grayscale style from SkMaps.bundle (if you're not using these styles)
3. Remove all other architectures but armv7 (there should be a small performance penalty on arm64, but since you exclude an entire set of architectures the size of the .ipa should be considerable smaller) - this change will be visible in the final .ipa file
