This page refers to version 0.6.2 of the Snowplow Objective-C Tracker, which is the latest version. Documentation for earlier versions is available:

• Version 0.5

• Version 0.1-0.3

• 1 Overview
• 2 Integration options
  • 2.1 Tracker compatibility
  • 2.2 Dependencies
• 3 Setup
  • 3.1 CocoaPods
  • 3.2 Manual setup
    • 3.2.1 FMDB Setup
    • 3.2.2 Reachability Setup
    • 3.2.3 Import all required frameworks
  • 3.3 Static setup
    • 3.3.1 OpenIDFA Setup

The Snowplow Objective-C Tracker lets you add analytics to your iOS, OSX and tvOS applications.

The Tracker should be relatively straightforward to setup if you are familiar with iOS/OSX development using CocoaPods.

Ready? Let's get started.

With iOS backward compatibility is limited to a small range which it makes it easy to support. Hence, our goal was to make the iOS Tracker compatible with iOS 7+ with easy availability via CocoaPods.

• For iOS the Tracker has dependencies limited to the FMDB and Reachability libraries for database management and network information respectively. Both of which have iOS 7+ support as well.

• For OSX and tvOS the Tracker has dependencies limited to FMDB for database management.

If you're installing via CocoaPods, the dependencies are recursively downloaded for your project so you don't have to worry about it.

We support installing the Objective-C Tracker via CocoaPods since it's the easiest way to install the tracker. Doing so is simple:

1. Install CocoaPods using gem install cocoapods
2. Create the file Podfile in the root of your XCode project directory, if you don't have one already
3. Add the following line into it:

pod 'SnowplowTracker'

4. Run pod install in the same directory

If you prefer not to use CocoaPods, you can grab the tracker from our GitHub repo and import it into your project.

First, git clone the latest version of the tracker to your local machine:

git clone https://github.com/snowplow/snowplow-objc-tracker.git

If you don't have git installed locally, install it first.

You only need to copy the tracker's Snowplow sub-folder into your XCode project's folder. The command will look something like this:

cp -r snowplow-objc-tracker/Snowplow MyObjcApp/MyObjcApp/

Replace MyObjcApp with the name of your own app, and tweak the source code sub-folder accordingly.

Next, drag and drop the sub-folder MyObjcApp/MyObjcApp/Snowplow into your XCode project's workspace:

Make sure that the suggested options for adding Snowplow are set Create groups, then click Finish:

The tracker is dependent on FMDB version 2.3, an Objective-C wrapper around SQLite.

As before, git clone the dependency and copy the source into your XCode project's folder:

git clone https://github.com/ccgus/fmdb.git
cd fmdb && git checkout v2.3
cp -r src/fmdb ../MyObjcApp/MyObjcApp/

As before, drag and drop the sub-folder MyObjcApp/MyObjcApp/fmdb into your XCode project's workspace, making sure to Create groups.

Finally, you will need to edit Snowplow/SPEmitter.m and Snowplow/SPEventStore.m in X-Code and change:

#import <FMDB.h>

to:

#import "FMDB.h"

Back to top

For iOS only, the tracker is dependent on Reachability version 3.2, a drop in replacement for Apple's Reachability class.

As before, git clone the dependency and copy the source into your XCode project's folder:

git clone https://github.com/tonymillion/Reachability.git
cd Reachability && git checkout v3.2
cp Reachability.{h,m} ../MyObjcApp/MyObjcApp/

Now add the Reachability.{h,m} files to your project by:

• Right-clicking on your MyObjcApp folder in XCode
• Selecting Add Files to "MyObjcApp"...
• Selecting both Reachability files and adding them

Once you have added the .h/m files to the project:

• Go to Projects->TARGETS->Build Phases->Link Binary With Libraries
• Press the plus in the lower left of the list
• Add SystemConfiguration.framework

Back to top

The tracker also depends on various frameworks:

$ grep 'frameworks' ../snowplow-objc-tracker/SnowplowTracker.podspec
  s.ios.frameworks = 'CoreTelephony', 'UIKit', 'Foundation'
  s.osx.frameworks = 'AppKit', 'Foundation'

Go to Target > General tab > Linked Frameworks and Libraries section and add:

1. All of the frameworks for your target platform, as returned by the grep above
2. libsqlite3.dylib

This is what adding the frameworks to an OS-X application looks like:

Now Build your project and you should see Build Succeeded. If you get a build error, check that you added Snowplow and fmdb as Groups, not just as Folders.

You are now ready to proceed to instrumenting your app. Just remember to use quotation marks not angle brackets, and the Snowplow sub-folder as necessary when importing the tracker:

#import "SPTracker.h"
#import "SPEmitter.h"

Currently the Static Library is only available for iOS, not for OS-X.

We also now support including the SnowplowTracker as a static library import.

• Download the static library's zipfile from bintray
• Unzip the static library's zipfile to a location (doesn't need to be inside your app)
• Go to Projects->TARGETS->Build Phases->Link Binary With Libraries
• Press the plus in the lower left of the list
• Navigate to where you downloaded the Tracker to and then add the framework

To activate the library:

• Go to Projects->TARGETS->Build Settings
• Make sure you are browsing All settings, not just Basic
• Search for Other Linker Flags
• Ensure that the -ObjC flag has been added

To import the library headers into your project you will need to add them with the name of the library prepended like so:

#import "SnowplowTracker/SPTracker.h"

This portion was based on the developers guide from Apple on importing static libraries.

Please note that you will need to add in all Tracker dependencies manually as they are not included in the static download.

• To add FMDB: FMDB Setup
• To add Reachability: Reachability Setup
• To add the required frameworks: Import all required frameworks

If you are embedding this app in an iOS app, then you will need to add OpenIDFA, which has been intentionally excluded from the Static Library.

Do not add OpenIDFA for a OS-X app.

As before, git clone the dependency and copy the source into your XCode project's folder:

git clone https://github.com/ylechelle/OpenIDFA.git
git checkout 382db601ca12a7710b8fe583e710f9cfcbf42c4f
cd OpenIDFA
cp OpenIDFA.{h,m} ../MyObjcApp/MyObjcApp/

Now add the OpenIDFA.{h,m} files to your project by:

• Right-clicking on your MyObjcApp folder in XCode
• Selecting Add Files to "MyObjcApp"...
• Selecting both OpenIDFA files and adding them
