How to make program wait for asynchronous NSURLConnection to finish before proceeding with next command?

Question

How can I make my program wait for an asynchronous NSURLConnection to finish before going to the next line of code?

SetDelegate *sjd= [SetDelegate alloc];
NSURLC         


        

Answer 1

If you really want it to wait, why use an asynchronous call at all? Use a synchronous call instead:

NSURLResponse* response = nil;
NSData* data = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:nil]

This approach will block the thread it's executed, so you should be sure you want to do it! Did I mention that it will block? :)
