(iOS) Manually throw Exceptions?

I'm very new to Raygun and I have a question about iOS Exception handling. I have the framework installed into an existing app, and it is working great for unexpected exceptions that are thrown. My question is, is there a way to manually log exceptions or errors without actually throwing an NSException?

I have a few places in my application where I would like to log custom events that I am not currently throwing an NSException. Like most apps, mine has a number of web services that it uses to communicate with the server (web services that I do not maintain or update). Right now my app just notifies the user that getting information from the web service response has failed (I am passed some gobbledegook .NET error), but I would like to manually send an error to Raygun so I am aware of the web service problem without actually throwing an exception inside of my app. Am I thinking about this wrong? I've tried throwing my own exceptions, but I don't want my app to crash so I have them inside of a try / catch. How can I manually send exceptions to Raygun from inside of a try / catch (like I do in Javascript)?

Jason,

That's great news! Thanks for getting back to me. FYI - I'm absolutely loving your service!

Best Regards,

Geoff
