objective c - How to get an array from NSMutableData -

-

i have text file 5 strings. need use nsurlconnection contnent of file. nslog shows me, 'dump' empty. how can transform data nsmutabledata nsarray. arrays because need show 5 items in tableview.

nsurlrequest *therequest=[nsurlrequest                          requestwithurl:[nsurl urlwithstring:@"http://dl.dropbox.com/u/25105800/names.txt"]                          cachepolicy:nsurlrequestuseprotocolcachepolicy                          timeoutinterval:60.0];  nsurlconnection *theconnection=[[nsurlconnection alloc] initwithrequest:therequest delegate:self]; if (theconnection) {     receiveddata = [nsmutabledata data];     nsstring *dump = [[nsstring alloc] initwithdata:receiveddata                          encoding:nsutf8stringencoding];     nslog(@"data: %@", dump);     nsarray *outputarray=[dump componentsseparatedbystring:@"\n"];     self.namesarray = outputarray;

thanks in advance. btw url works, can see file.

if don't want use delegate, can use synchronous call nsurlconnection, this:

nsurlrequest *therequest=[nsurlrequest                      requestwithurl:[nsurl urlwithstring:@"http://dl.dropbox.com/u/25105800/names.txt"]                      cachepolicy:nsurlrequestuseprotocolcachepolicy                      timeoutinterval:60.0];  nserror *error = nil; nshttpurlresponse *response = nil; nsdata *receiveddata = [nsurlconnection sendsynchronousrequest:therequest response:&response error:&error];  if (error == nil) {     nsstring *dump = [[nsstring alloc] initwithdata:receiveddata                      encoding:nsutf8stringencoding];     nslog(@"data: %@", dump);     nsarray *outputarray=[dump componentsseparatedbystring:@"\n"];     self.namesarray = outputarray; }

just beware not running asynchronously. if don't want run on main thread , block main thread/ui, consider using separate thread execute code or use gcd.
