Data Collection iOS

Data Collection for iOS shows how a robust application can be built around the ArcGIS Platform using the ArcGIS Runtime SDK for iOS and Swift. It demonstrates best practices around some simple but key functionality of the ArcGIS Runtime. Using your organization's web maps, you can use Data Collection as is, or extend it to meet your specific needs.

General UI

Features

  • Taking your web map and data offline
  • Editing your data both offline and online
  • Synchronizing offline edits
  • Viewing and editing your data with Popups
  • Working with Features, Popups and PopupManagers
  • Editing and querying Feature Tables
  • Working with related records
  • Identifying map features
  • Portal authentication with OAuth
  • Using the World Geocoder service
  • Using Popup configuration to drive app behavior

Best Practices

The project also demonstrates some patterns for building real-world apps around the ArcGIS Runtime SDK.

  • Map-centric UI design
  • ArcGIS asynchronous service pattern
  • Swift class extensions
  • Swift KVO & NotificationCenter state handling

Get Started

You will need Xcode 10.2 and the ArcGIS Runtime SDK (v100.5 or later) installed locally.

Fork the repo

Fork the Data Collection repo

Clone the repo

Once you have forked the repo, you can make a clone and open data-collection.xcodeproj in Xcode.

Command line Git

  1. Clone Data Collection
  2. cd into into the cloned repository's directory
  3. Make your changes and create a pull request

Configuring a Remote for a Fork

If you make changes in the fork and would like to sync those changes with the upstream repository, you must first configure the remote. This will be required when you have created local branches and would like to make a pull request to your upstream branch.

  1. In the Terminal (for Mac users) or command prompt (for Windows and Linux users) type git remote -v to list the current configured remote repo for your fork.
  2. git remote add upstream https://github.com/Esri/data-collection-ios.git to specify new remote upstream repository that will be synced with the fork. You can type git remote -v to verify the new upstream.

If there are changes made in the Original repository, you can sync the fork to keep it updated with upstream repository.

  1. In the terminal, change the current working directory to your local project
  2. Type git fetch upstream to fetch the commits from the upstream repository
  3. git checkout master to checkout your fork's local master branch.
  4. git merge upstream/master to sync your local master branch with upstream/master. Note: Your local changes will be retained and your fork's master branch will be in sync with the upstream repository.

Configure the app

The app can be run as is, but it's recommended you do some configuration to set up OAuth to be relevant to your users. At minimum, the app should not be deployed without these changes:

  1. Register an ArcGIS Portal Application.
  2. Configure Data Collection project to reference that application.
  3. License the app to remove the Developer Mode watermark and for deployment.

1. Register an Application

For OAuth configuration, create a new Application in your ArcGIS Portal to obtain a Client ID and configure a Redirect URL. The Client ID configures the ArcGIS Runtime to show your users, during the login process, that the application was built by you and can be trusted. The Redirect URL configures the OAuth process to then return to your app once authentication is complete.

  1. Log in to https://developers.arcgis.com with either your ArcGIS Organizational Account or an ArcGIS Developer Account.
  2. Register a new Application. Register ArcGIS Application
  3. In the Authentication tab, note the Client ID and add a Redirect URL, e.g. data-collection://auth. We will use this URL in the Configuring the project section below. Configure ArcGIS Application

2. Configuring the project

Configure Redirect URL

Configure Xcode Project

  1. Open the project in Xcode and browse to the file named AppConfiguration.swift located in the data-collection directory.
  2. (Optionally) configure your organization's base portal domain and web map item id.
  3. Configure the OAuth Redirect URL.
    • Set the urlScheme property to match the Redirect URL scheme (the part before the ://, e.g. data-collection).
    • Set the urlAuthPath property to match the OAuth Redirect Path (the part after the ://, e.g. auth).
    • (Note how the urlScheme and urlAuthPath combine to construct the OAuth Redirect URL.)
  4. Configure the license key and client ID.
    • Set licenseKey property with your organization's license. This step is optional during development but required for deployment. Licensing the app will remove the "Licensed for Developer Use Only" watermark on the map view.
    • Set the clientID property with the client ID generated when you registered your application (see section above).
  5. Navigate to the project -> the target named data-collection -> Info pane, and configure the URL Schemes to the same scheme configured in step 3 (e.g. data-collection).

3rd Party Component Licensing

Some great open source components are available out there for iOS developers. The following have been used in this project, with much gratitude to their authors.

You can’t perform that action at this time.
