How can I debug objects on XCode the same way I do in Eclipse?

I'd like to see the content of NSObjects like properties ( arrays, Integers, floats... ). Since I'm a Flex developer I'm used to use the eclipse debugging tool. But now I'm starting with the iPhone I'm kind of lost.

For example, I just downloaded the SeismicXML application from the dev's sample code, and I put a breakpoint on the connectionDidFinishLoading and parseEarthquakeData methods.

I'd like to print the data ( the xml ) but I don't know how.

THe only thing I could achieve is to print the object using the po command on the gdb.

Any idea?

Note: XCode 4 and above has improved the debugging system.

Solution

Unfortunately the visual property viewer doesn't seem to be as nice as I'd like. I spend a good chunk of my time in the gdb console issuing all kinds of crazy print statements.
