How do I get hour and minutes from NSDate?

Use an NSDateFormatter to convert string1 into an NSDate, then get the required NSDateComponents:

Obj-C:

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];[dateFormatter setDateFormat:@"<your date format goes here"];NSDate *date = [dateFormatter dateFromString:string1];NSCalendar *calendar = [NSCalendar currentCalendar];NSDateComponents *components = [calendar components:(NSCalendarUnitHour | NSCalendarUnitMinute) fromDate:date];NSInteger hour = [components hour];NSInteger minute = [components minute];

Swift 1 and 2:

let dateFormatter = NSDateFormatter()dateFormatter.dateFormat = "Your date Format"let date = dateFormatter.dateFromString(string1)let calendar = NSCalendar.currentCalendar()let comp = calendar.components([.Hour, .Minute], fromDate: date)let hour = comp.hourlet minute = comp.minute

Swift 3:

let dateFormatter = DateFormatter()dateFormatter.dateFormat = "Your date Format"let date = dateFormatter.date(from: string1)let calendar = Calendar.currentlet comp = calendar.dateComponents([.hour, .minute], from: date)let hour = comp.hourlet minute = comp.minute

More about the dateformat is on the official unicode site

If you only need it for presenting as a string the following code is much easier

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];[formatter setDateFormat:@"HH:mm"];NSString *startTimeString = [formatter stringFromDate:startTimePicker.date];

This seems to me to be what the question is after, no need for formatters:

NSDate *date = [NSDate date];NSCalendar *calendar = [NSCalendar currentCalendar];NSDateComponents *components = [calendar components:(NSCalendarUnitHour | NSCalendarUnitMinute) fromDate:date];NSInteger hour = [components hour];NSInteger minute = [components minute];
