Using Mixpanel Analytics on iOS

If you want to track user behavior on your iPhone\iPad application, first download the Mixpanel iOS API by cloning the git repository:

git clone https://github.com/mixpanel/mixpanel-iphone.git

Or download the latest zip archive and extract the files. The respository has three folders:

1. Mixpanel - The Mixpanel iOS library and its dependencies.
2. HelloMixpanel - A sample application that tracks events and sets user properties using Mixpanel.
3. Docs - Headerdoc API reference.

Setup

Adding Mixpanel to your Xcode project is as easy as:

1. Drag and drop the Mixpanel folder into your project.
2. Check the "Copy items into destination Group's folder" and select Recursively create groups for any added folders.

3. Make sure the following Apple frameworks have been added to your project in Targets > Build Phases > Link Binary With Libraries:

• Foundation.framework
• UIKit.framework
• SystemConfiguration.framework
• CoreTelephony.framework
• AdSupport.framework

And that's it.

Initializing Mixpanel

The first thing you need to do is initialize Mixpanel with your project token. We recommend doing this in applicationDidFinishLaunching: or application:didFinishLaunchingWithOptions in your Application delegate.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    

    // Override point for customization after application launch.
	[Mixpanel sharedInstanceWithToken:MIXPANEL_TOKEN];

    // Add the view controller's view to the window and display.
    [window addSubview:viewController.view];
    [window makeKeyAndVisible];
    return YES;
}

Tracking Events

After initializing the Mixpanel object, you are ready to track events. This can be done with the following code snippet:

Mixpanel *mixpanel = [Mixpanel sharedInstance];
[mixpanel track:@"Clicked Button"];

If you want to add properties to the event you can do the following:

Mixpanel *mixpanel = [Mixpanel sharedInstance];
[mixpanel track:@"Player Create" 
     properties:[NSDictionary dictionaryWithObjectsAndKeys:@"Female", @"Gender", @"Premium", @"Plan", nil]];

Setting People Properties

Use the people accessor on the Mixpanel object to make calls to the Mixpanel People API. Unlike Mixpanel Engagement, you must explicitly set the distinct ID for the current user in Mixpanel People.

Mixpanel *mixpanel = [Mixpanel sharedInstance];
[mixpanel identify:@"user123"];
[mixpanel.people set:@"Bought Premium Plan" to:[NSDate date]];

To send your users push notifications through Mixpanel People, register device tokens as follows.

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)devToken {
    [self.mixpanel.people addPushDeviceToken:devToken];
}

ARC

The Mixpanel library does not currently use ARC. We've chosen to do this because a large number of customers have not moved to ARC yet. To integrate with an ARC project: Go to Project > Target > Build Phases, double-click on each Mixpanel file and add the flag: -fno-objc-arc.

Logging

You can turn on Mixpanel logging by adding the following Preprocessor Macros in Build Settings: MIXPANEL_LOG=1 and MIXPANEL_DEBUG=1. Setting MIXPANEL_LOG=1 will cause the Mixpanel library to log tracked events and set People properties. Setting MIXPANEL_DEBUG=1 will cause Mixpanel to log everything it's doing—queuing, formatting and uploading data—in a very fine-grained way, and is useful for understanding how the library works and debugging issues.
