Pixalate Mobile SDK Implementation in iOS Objective-C (Measurement)

A guide to integrate Pixalate's light-weight impression library for mobile SDK implementation in your iOS app. This library facilitates the construction and sending of impression URLs with the key values needed by Pixalate for IVT measurement.

For Pixalate clients and users, please login to access this page with additional information.

Accessing the Library

You can install the library using CocoaPods, or by cloning the repository directly.


Simply add the library as a dependency in your project's Podfile:

pod 'pixalate-ios-sdk'

Then install it into the project using the pod update terminal command.


First, clone the repository from here: https://github.com/pixalate-inc/pixalate-ios-sdk.

Drag the downloaded pixalate-ios-sdk folder (containing the .h and .m files) into your project, ensuring that the "Copy items if needed" checkbox is checked. If necessary, you may need to add the folder to your header search paths.


Wherever you are planning to use the library, simply ensure that you import "Pixalate.h".

Sample Project

A sample implemention utilizing the MoPub SDK is available via the project's GitHub repository, under the sample-app-objc folder.

Building the Sample Project

  1. Clone the repository to your computer.
  2. Open a Terminal window to the sample app's folder.
  3. Run pod install, and then open the generated sample-app-obj.xcworkspace.

Impression API

Building Impressions

Creation of immutable impression objects is done through the use of a builder helper class. To make a new impression, it is easiest to use the class method +[PXImpression makeWithClientId:builder:].  This method takes a block in which you can define all of your relevant values at once. 

If you don't want to use the block method, you can also initialize the builder yourself and pass it to -[PXImpression initWithBuilder:].

For your convenience, parameter names are mapped as human-readable string constants. The available constants are outlined below and please contact your Customer Success representative for sample code blocks and full string values.

The impression builder accepts any value as a parameter name. The mappings outlined above are merely provided as a convenience for commonly used parameters.

You must explicitly provide the impression builder with all parameters that you are able to include.

Sending Impressions

To send an impression, pass your built PXImpression instance to the +[Pixalate sendImpression:] class method:

PXImpression *impression = /* create an impression using your preferred method */;
[Pixalate sendImpression: impression];

Building and sending of impressions can be compacted into a one-line call, if you do not wish to pre-build impression data. Please contact your Customer Success representative for sample code blocks and full string values. 

When to Send Impressions

In order to have the most accurate and MRC-compliant results from integration with Pixalate's impression library, it is important to place your impression snippet at the correct location within your ad code. For example, if you want to record impressions for a banner ad using MoPub's iOS SDK, they provide an MPAdViewDelegate protocol that you can set up on your MPAdView.

It's important that the impression is sent as close to the actual impression event as possible. If you retrieve an ad, make sure that you only send an impression if you intend to show it.
