Answer 1

1. As stated you’re assigning to dbrc without using it. You could just leave out the assignment if you’re not going to use the error code.

   sqlite3_prepare_v2(...);
   ...
   while (sqlite3_step(...) == SQLITE_ROW) {
     ...
   

2. If the for loop above is not run (i.e. the regex fails to match), then matchOk will never be initialized, i.e. it contains garbage.

   NSString* matchOK = nil;
   int nM = 0;
   ...
   

3. You have +alloced a NSURLConnection but never store the result anywhere, thus to the analyzer there is no chance -releaseing it afterwards. This causes a leak.

4. You have +alloced a TickerSessions without -releaseing it.

Actually you could open the Build Results window to see what triggers the error.
