iOS API equivalents of -js APIs

[kristfal]

Hello,

probably more of a question rather than an issue, feel free to close it if it's in the wrong place.

Been working with the -js client for a while (which is really awesome), and has just started looking at the native iOS client.

Do the native client support altering layers on the fly in a similar fashion to the -js?

Been looking through this, but can't find anything that seems to resemble the javascript API calls.

I have successfully added layers using a recent version of master using the style methods.

You have to be familiar with the style spec and first add your map ID to sources and then configure the rendering in layers.

If you want to do it on the fly within the app, you have the manipulate the NSDictionary fetched using getRawStyle and then call setRawStyle which updates instantly.

That was very ugly, I'm not sure if setStyleOrderedLayerNames will add layers or just re-order? It doesn't seem to be in the header file, though...

You can also take one of the current styles bundled in the repo, change it and use that instead of the named one by calling setStyleJSON or setRawStyle if you load it into an NSDictionary.

We'll add an explicit API for altering styles eventually. Duplicate of #837.
