Question

I have this code, I save total second counting and load it in result view controller. and in my result view controller, I put this code,

- (void) counting
{
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    NSNumber *loadSecond = [defaults objectForKey:@"saveSecond"];
    NSLog(@"last save is %@", loadSecond); // in here, log is displaying 30 seconds
    scratch = fmod(secondCount,3600);
    hour =  secondCount / 3600;
    minute = scratch / 60;
    second = fmod(scratch,60);
    labelRecord.text = [NSString stringWithFormat:@"%d:%d:%d", hour , minute, second];
}

From above, NSLog is displaying my last save counting for 30 seconds, and it is right but how do i change that 30 seconds to secondCount? because i want use it in my labelRecord.

Change this line

NSNumber *loadSecond = [defaults objectForKey:@"saveSecond"];

to

int loadSecond = [[defaults objectForKey:@"saveSecond"] intValue];

This assumes that the object for the key saveSecond is a NSNumber.
