How do I parse JSON with Objective-C?

I am new to iPhone. Can anyone tell me the steps to follow to parse this data and get the activity details, first name, and last name?

    \"#error\": fals

Don't reinvent the wheel. Use json-framework or something similar.

If you do decide to use json-framework, here's how you would parse a JSON string into an NSDictionary:

SBJsonParser* parser = [[[SBJsonParser alloc] init] autorelease];
// assuming jsonString is your JSON string...
NSDictionary* myDict = [parser objectWithString:jsonString];

// now you can grab data out of the dictionary using objectForKey or another dictionary method
