Omarj's answer looks good for simple testing purposes, but I like to use this code:

NSDateComponents *changeComponent = [[NSDateComponents alloc] init];
changeComponent.second = 20;

NSCalendar *theCalendar = [NSCalendar currentCalendar];
NSDate *newDate = [theCalendar dateByAddingComponents:changeComponent toDate:[NSDate date] options:0];


As you can see, you can change the changeComponent to minutes, hours, days, or in my case, seconds! This is very useful for testing local notifications that I am currently working on.

The best advantage of this solution is that it respects the calendar, so there should be no problem adding hours when daylight saving time changes.

Please check this code.

    NSString* dateString = @"9:33AM";
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"hh:mma"];
[formatter setTimeZone:[NSTimeZone timeZoneWithName:@"UTC"]];
NSDate *date = [formatter dateFromString:dateString];
NSLog(@"Before Adding time %@",date);
NSDate *newDate = [date dateByAddingTimeInterval:14*60];
NSLog(@"After adding time %@",[formatter stringFromDate:newDate]);
