I am not sure if i am asking the right question or not.
I have a singleton class as below:

static DBHandler *dbHandler = nil;

+(DBHandler *)sharedDBHandler {

    @synchronized(self) {
        if(nil == dbHandler) {

            dbHandler = [[[self class] alloc] init];
        }
    }

    return dbHandler;
}

When and where to release a Singleton instance in Objective-C ?

Thanks,

    Most often they are located in static memory which means they are handled differently. See this question:
