(5) class member names starting with '_' are reserved fro Apple. Don't name yours that way. (10) iPhone apps should never call exit(). Let the user do it, instead, in your application delegate, implement -(void)applicationWillTerminate: and do the synchronize there. (1) is your bug: you are trying to use == on strings, (which is pointer equality) when you mean [aS isEqual:bS]; (but beware: [nil isEqual:nil] returns NO.) you point that out yourself as point (9)

(4) should be:float F = ((float)x) / y; since in C, C++, Objective-C and Objective-C++ division of integers produces an integer result.

(5) class member names starting with ‘_’ are reserved fro Apple. Don’t name yours that way.

(10) iPhone apps should never call exit(). Let the user do it, instead, in your application delegate, implement -(void)applicationWillTerminate: and do the synchronize there.

Wish there was a way to leave them in there but globally turn them off. Great information – I didn’t realize that NSLog slowed things down so much.
