So what exactly I should do in the start() method??
Whatever you need to do to start the operation. It should return ASAP since it's not being run on a background thread.
If I create a thread,does the operation queue still enforce maxConcurrentOperationCount or I needto worry about that in my implementation?
If you have to start a new thread, you probably just want to use the default synchronous NSOperation mode. The concurrent mode is for when your code is asynchronous — for example, you're using NSURLConnection and kick off the connection in the -start method, and then set yourself as the delegate and wait for callbacks.
But the answer to your question is yes — the queue will only allow a fixed number of operations to be running at once, sync or async.
