{
sqlite3 *db;
sqlite3_stmt * stmt;
std::vector< std::vector < std:: string > > result;

Local variable assign versus direct assign; properties and memory
by Miklebud in Programming Languages

In objective-c I see a lot of sample code where the author assigns a local variable, assigns it to a property, then releases the local variable. Is there a practical reason for doing this?

by DesiPower in Development Tools & Services

Basically what I'm trying to achieve is to make the object reference another object of the same class - from inside of a method. It'd be perfect if the following would work:
