objective c - Retrieving hours in 24 hour format in iphone

I am using this format to get hours

   NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    dateFormatter.dateFormat = @"hh";
    [dateFormatter setTimeZone:[NSTimeZone systemTimeZone]];

    NSString *date = [dateFormatter stringFromDate:now];

    NSInteger myHour = [date intValue];

The problem is it returns e.g 4Pm i Want it to return 16 Instead of 4. How can I do that? I tried replacing hh by single h by of no avail.

Here Your input:

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"hh"];
NSDate *Yourcurrenttime = [dateFormatter dateFromString:Yourstring];

And date converted to the String ..

[dateFormatter setDateFormat:@"HH"];
NSString *date = [dateFormatter stringFromDate:now];

NSInteger myHour = [date intValue];
