Question

I am parsing a JSON string:

Response: {"success":false,"displaymessage":"UserName or Email already exist. Please try again"}

The code I am using is:

  NSLog(@"Result: %@ %@", [responseObject valueForKeyPath:@"success"]? @"YES" : @"NO", [responseObject valueForKeyPath:@"displaymessage"]);

However my out put is:

Result: YES UserName or Email already exist. Please try again

I should be getting a No. What am I doing wrong?

The valueForKeyPath: method returns an object, which is always non-nil (hence you’re seeing a YES instead of a NO). If I remember it correctly, booleans are wrapped in NSNumber. You should pull the actual boolean value from the object returned by valueForKeyPath:, like this:

[[responseObject valueForKeyPath:@"success"] boolValue]? @"YES" : @"NO"
