Summary

This is the iOS SDK of AdjustIo. You can read more about AdjustIo at adjust.io.

Basic Installation

These are the minimal steps required to integrate the AdjustIo SDK into your iOS project. We are going to assume that you use Xcode for your iOS development.

If you're using CocoaPods, you can add the following line to your Podfile and continue with step 3:

pod 'AdjustIO', :git => 'git://github.com/adeven/adjust_ios_sdk.git', :tag => 'v2.2.0'

1. Get the SDK

Download the latest version from our releases page. Extract the archive in a folder of your choice.

2. Add it to your project

In Xcode's Project Navigator locate the Supporting Files group (or any other group of your choice). From Finder drag the AdjustIo subdirectory into Xcode's Supporting Files group.

In the dialog Choose options for adding these files make sure to check the checkbox to Copy items into destination group's folder and select the upper radio button to Create groups for any added folders.

3. Add the AdSupport framework

In the Project Navigator select your project. In the left hand side of the main view select your target. In the tab Build Phases expand the group Link Binary with Libraries. On the bottom of that group click on the + button. Select the AdSupport.framework and click the Add button. In the list of frameworks select the newly added AdSupport.framework and change the attribute Required to Optional.

4. Integrate AdjustIo into your app

In the Project Navigator open the source file your Application Delegate. Add the import statement at the top of the file. In the didFinishLaunching or didFinishLaunchingWithOptions method of your App Delegate add the following calls to AdjustIo:

#import "AdjustIo.h"
// ...
[AdjustIo appDidLaunch:@"{YourAppToken}"];
[AdjustIo setLogLevel:AILogLevelInfo];
[AdjustIo setEnvironment:AIEnvironmentSandbox];

Replace {YourAppToken} with your App Token. You can find in your dashboard.

You can increase or decrease the amount of logs you see by calling setLogLevel: with one of the following parameters:

[AdjustIo setLogLevel:AILogLevelVerbose]; // enable all logging
[AdjustIo setLogLevel:AILogLevelDebug];   // enable more logging
[AdjustIo setLogLevel:AILogLevelInfo];    // the default
[AdjustIo setLogLevel:AILogLevelWarn];    // disable info logging
[AdjustIo setLogLevel:AILogLevelError];   // disable warnings as well
[AdjustIo setLogLevel:AILogLevelAssert];  // disable errors as well

Depending on whether or not you build your app for testing or for production you must call setEnvironment: with one of these parameters:

[AdjustIo setEnvironment:AIEnvironmentSandbox];
[AdjustIo setEnvironment:AIEnvironmentProduction];

Important: This value should be set to AIEnvironmentSandbox if and only if you or someone else is testing your app. Make sure to set the environment to AIEnvironmentProduction just before you publish the app. Set it back to AIEnvironmentSandbox when you start testing it again.

We use this environment to distinguish between real traffic and artificial traffic from test devices. It is very important that you keep this value meaningful at all times! Especially if you are tracking revenue.

5. Build your app

Build and run your app. If the build succeeds, you successfully integrated AdjustIo into your app. After the app launched, you should see the debug log Tracked session start.

Troubleshooting

• If your build failed because of many duplicate symbols, you were probably already using AFNetwork before integrating AdjustIo. Just remove the AdjustIo/AFNetworking group from your Project Navigator to resolve this issue.

• If your build failed with the error AdjustIo requires ARC, it looks like your project is not using ARC. In that case we recommend transitioning your project to use ARC. If you don't want to use ARC, you have to enable ARC for all source files of AdjustIo in the target's Build Phases:

  Expand the Compile Sources group, select all AdjustIo files (AjustIo, AI..., ...+AIAdditions, AF..., ...+AFNetworking) and change the Compiler Flags to -fobjc-arc (Select all and press the Return key to change all at once).

Additional features

Once you integrated the AdjustIo SDK into your project, you can take advantage of the following features.

Add tracking of custom events.

You can tell AdjustIo about every event you want. Suppose you want to track every tap on a button. You would have to create a new Event Token in your dashboard. Let's say that Event Token is abc123. In your button's buttonDown method you could then add the following line to track the click:

[AdjustIo trackEvent:@"abc123"];

You can also register a callback URL for that event in your dashboard and we will send a GET request to that URL whenever the event gets tracked. In that case you can also put some key-value-pairs in a dictionary and pass it to the trackEvent method. We will then append these named parameters to your callback URL.

For example, suppose you have registered the URL http://www.adeven.com/callback for your event with Event Token abc123 and execute the following lines:

NSMutableDictionary *parameters = [NSMutableDictionary dictionary];
[parameters setObject:@"value" forKey:@"key"];
[parameters setObject:@"bar"   forKey:@"foo"];
[AdjustIo trackEvent:@"abc123" withParameters:parameters];

In that case we would track the event and send a request to:

http://www.adeven.com/callback?key=value&foo=bar

It should be mentioned that we support a variety of placeholders like {idfa} that can be used as parameter values. In the resulting callback this placeholder would be replaced with the ID for Advertisers of the current device. Also note that we don't store any of your custom parameters, but only append them to your callbacks. If you haven't registered a callback for an event, these parameters won't even be read.

Add tracking of revenue

If your users can generate revenue by clicking on advertisements or making in-app purchases you can track those revenues. If, for example, a click is worth one cent, you could make the following call to track that revenue:

[AdjustIo trackRevenue:1.0];

The parameter is supposed to be in cents and will get rounded to one decimal point. If you want to differentiate between different kinds of revenue you can get different Event Tokens for each kind. Again, you need to create those Event Tokens in your dashboard. In that case you would make a call like this:

[AdjustIo trackRevenue:1.0 forEvent:@"abc123"];

Again, you can register a callback and provide a dictionary of named parameters, just like it worked with normal events.

NSMutableDictionary *parameters = [NSMutableDictionary dictionary];
[parameters setObject:@"value" forKey:@"key"];
[parameters setObject:@"bar"   forKey:@"foo"];
[AdjustIo trackRevenue:1.0 forEvent:@"abc123" withParameters:parameters];

If you want to track In-App Purchases, please make sure to call trackRevenue after finishTransaction in paymentQueue:updatedTransaction only if the state changed to SKPaymentTransactionStatePurchased:

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {
    for (SKPaymentTransaction *transaction in transactions) {
        switch (transaction.transactionState) {
            case SKPaymentTransactionStatePurchased:
                [self finishTransaction:transaction];
                [AdjustIo trackRevenue:...];
                break;
            // more cases
        }
    }
}

Enable event buffering

If your app makes heavy use of event tracking, you might want to delay some HTTP requests in order to send them in one batch every minute. You can enable event buffering by adding the following line after your setEnvironment: call in the didFinishLaunching method of your Application Delegate:

[AdjustIo setEventBufferingEnabled:YES];
