Calculate time difference in Cocoa

Question

I have got two timevalues in the format: %H%M%S (E.G.161500)

These values are text-based integers.

Is there a simple function in Cocoa that calculates the diffe

Answer 1

NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter setDateFormat:@"HHmmss"];

NSDate *date1 = [dateFormatter dateFromString:@"161500"];
NSDate *date2 = [dateFormatter dateFromString:@"171500"];

NSTimeInterval diff = [date2 timeIntervalSinceDate:date1]; // diff = 3600.0
