DataWithContentsOfURL vs NSURLConnection?

Sure, first let me say that implementing NSURLConnection as an operation it's little bit tricky, but it has a lot of advantages. First you can use callbacks, to manage authentications, upload bar, etc. Second you can manage multiple connection asynchronously on a secondary thread, with sync op you block the thread where the method is running in until it finishes.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
