I got JSON framework files from downloaded example. The examples are working perfectly, but my project showing above errors.

Symbol(s) not found for architecture i386

The above error occurs in the following situation:

1. You were trying to run your application in the iPhone/iPad Simulator
2. The library was only built to run on the physical devices, and does not support being run in the Simulator.

To resolve this, you either need to add i386 to the Valid Architectures of the SBJSON library build target, or test your application using a physical device.
