Question

I have an NSString with the value @"1:10:39"

What’s the fastest / most convenient way to convert this time to minutes? eg. 70.65

I’m not asking for a hand out here, show code only if you feel comfortable doing so. I’m mainly looking for a recommendation. Thanks.

Here’s one way.

NSString *zeroString = @"00:00:00";
NSString *timeString = @"1:10:39";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"HH:mm:ss"];
NSDate *zeroDate = [dateFormatter dateFromString:zeroString];
NSDate *offsetDate = [dateFormatter dateFromString:timeString];
NSTimeInterval timeDifference = [offsetDate timeIntervalSinceDate:zeroDate];
CGFloat minutes = (timeDifference/60);
NSLog(@"%0.2fmins",minutes);
