Stopwatch timer crash help?

[elfarez]

Hi for an app I have a timer which counts in increments of 1second, I would like to change this to increments of 0.1 seconds. It is an NSTimer and UILabel deal. Any suggestions?

Cheers

Somewhere in your code, when you create the NSTimer, you had to give it a value of 1.0 sections. Just change that to 0.1.

Thanks. Yeah thats what I thought but when I did that the timer didn't start. So I dunno, I'll try rewriting the code as I have searched it and haven't been able to find any flaws.

Ok, I know realise the problem the current time uses the intValue method. Does anyone know the method for decimal values?

All of Cocoa's date functions use either NSDate or NSTimeInterval. NSTimeInterval is a double precision floating point number, accurate to a few thousandths of a second.

It's probably YOUR code that uses an intValue. Post the code that is returning integer values and perhaps we can help you.


Code like this

NSTimeInterval startTime, endTime, elapsedTime;
startTime = [NSDate timeIntervalSinceReferenceDate];

... Do stuff that takes time...

endTime = [NSDate timeIntervalSinceReferenceDate];
elapsedTime = endTime - startTime;
NSLog(@"Elapsed time = %f seconds", elapsedTime);

Should let you calculate time in fractions of a second.
