13.1. NextGIS iOS SDK¶
NextGIS iOS SDK is a set of libraries used to support work with geodata in mobile applications for iPhone and iPad. The SDK includes:
The nextgis_datastore library is written in
С++11 and based on GDAL. The library supports the following functionality:
create, modify and delete geodata (raster and vector)
edit vector geodata (modify geometry and attributes)
geodata management (copy, move, various formats import/export, etc.)
geodata rendering as maps using OpenGL/OpenGL ES
utility functions (network requests, oAuth2, json)
NextGIS Webintegration (under development)
The library has
С API and bindings to android java/kotlin programming languages using
The ios_maplib library is written in
Swift and acts as easy wrapper around C API nextgis_datastore.
To use SDK the Xcode 8 or higher required. Also the
Carthage utility required. Carthage is intended to be the simplest way to add frameworks to your Cocoa application. To install Carthage follow instruction at Cathage site.
In your project folder create
Cartfile with following text:
In terminal execute command:
carthage update --platform "iOS"
The command will download and install all necessary components.
