Using Smart Proxy Manager with Objective-C#


All the code in this documentation has been tested with Xcode 13.1.

  1. In order to work with Objective-C make sure you have Xcode installed.

  2. Install the Zyte CA certificate for HTTPS request support.

  3. Create a new macOS Project and select Application > Command Line Tool.

  4. Copy entire Sample Code given below and paste in main.m.

  5. Replace <SPM-APIKEY> with Zyte Smart Proxy Manager API Key.

  6. Press Command + R to run the program or Select Product > Run from the Menu bar.

  7. The output can be found on Console. Active Console by pressing Shift + Command + C or by Selecting View > Debug Area > Activate Console from the Menu bar.
