How to obtain a free trial license
The Wikitude SDK requires a valid license key to be able to run properly. An empty or missing license key will block the augmented reality view from showing any meaningful content. You will see a watermark across the screen with the words License Key Missing. All JavaScript API calls will be ignored and not interpreted.
When downloading the Wikitude SDK you will be forwarded to the license generation page, where a trial license key is automatically generated for you.
Copy the key into your app, which will unlock the trial mode of the Wikitude SDK. The trial mode of the Wikitude SDK contains the full feature set of the Wikitude SDK but will show a Trial watermark across the screen.
Each trial license key is valid for every application ID on every operating system. You can use the same trial license key in multiple apps.
Where should I enter the license key
iOS
To use the Wikitude iOS SDK with a certain license key, use the method -setLicenseKey: defined in WTArchitectView.h and provide a valid license key.
The SDK Example application demonstrates the license handling in the file WTAugmentedRealityViewController.m. The license key is defined in line 22 and used in line 51.
