In order to run Dynamsoft Camera SDK iOS Edition within your app, you need a license key to activate it. You can either request a trial key or purchase a full license.
How to request for a trial key
Once logged in, please navigate to DCS Mobile License Center on the left panel.
How to extend trial key
After clicking "Extend License", the license will be extended for another month. The trial license can only be extended twice. It means three months free trial in total.
