And the computation sources are exactly byte-to-byte the same ones as
those
three-minutes-in-Terminal were?
It is exactly the same source code !
Following your sample : i took doComputer() and put it into a new
project (foundation tool project).
The _ONLY_ difference is that originally
there was something like
#import "ComputationPart.h" // doCompute there
...
int main(int ac,char**av) {
...
beginTimer();
doCompute();
endTimer(); // shown three minutes
...
}
whilst now there is something like
#import "ComputationPart.h" // doCompute there
...
@interface SomeController:NSObject
...
-(IBAction)launchComputations:sender {
beginTimer();
doCompute(); // EXACTLY THE SAME CODE CALLED
endTimer(); // shows three hours
}
? That just can't be, there has to be some hidden very, very big
gotcha. You
said you played with multithreading, can't that be the problem?
