Let me show you the code and explain what is going on. for (int x= 0; x <[appDelegate.people count]; x++) { Person *aPerson = [[Person alloc] init]; aPerson = [appDelegate.people objectAtIndex:x]; if ([appDelegate.groupedBusiness objectForKey:aPerson...

This is a pretty weird question I guess, but I've never really had to deal with memory allocation before so now I'm really paranoid about using too much of it or forgetting to deallocate stuff. I've found the extremely useful memory leak tool (and am quite proud to see that, so far at least, I'm not losing anything that way) and also the...

Is it common practice to do some kind of debouncing / refractory period for handling user touches? I have a view based app with quite a few UI objects that are currently using touchUpInside to flip states. I notice that its almost easy to double touch or cycle the state more than once. Since the gameplay is relatively fast it doesn't ...

But when I run the app directly from the simulator(which is already installed in the simulator) , it shows about 10 MB in the activity monitor and mem...
