OpenTreeMap for iOS

Getting Started

Service Dependencies

OpenTreeMap for iOS has 2 major web service dependencies:

  • An OpenTreeMap web application and ecobenefits service installation
  • An OpenTreeMap tiler installation

The source code for these services is available is available on Github:

Configuration files

The iOS application requires three configuration files:

  • OpenTreeMap/OpenTreeMap.entitlements
  • OpenTreeMap/OpenTreeMap-Info.plist
  • OpenTreeMap/skin/Implementation.plist

This repository contains templates for all three, and a Fabric command for generating OpenTreeMap-Info.plist.


This file can be generated with the following command, substituting a unique application name and bundle ID.

$ fab create_info_plist:app_name={app name},bundle_id={bundle id}


The template is available at OpenTreeMap/skin/Implementation.plist.template

Here is a description of the template variables within the file that need to be replaced.



The public portion of a valid OpenTreeMap API key that appears as a query string argument in all API requests.



The root URL of an OpenTreeMap installation.



The version of OpenTreeMap API being used by the iOS application. Should have the format "v4".



The environment name for messages logged to Rollbar.



The title of the main map view navigation controller.



The email address to which inappropriate content reports are sent.



The token used to connect to and log messages in Rollbar.



The private portion of a valid API key used to sign all API requests.



The splash screen image appears for this minimum number of seconds.



The root URL of the OpenTreeMap tiler service connected to the same database as the application specified by apiurl.



This is set to the url_name of an instance, the iOS application will only connect show that instance. Otherwise the iOS application will show a list of all available instances for the user to choose from.


A template for this file is available at OpenTreeMap/OpenTreeMap.entitlements.template.

The app_id variable should be replaced with a unique App ID.

Images and Other Content

This repository contains placeholder images for the user interface widgets, icons, and splash screens, along with a default about.html page. These should be replaced with your own content.
