How do I get hour and minutes from NSDate?

Question

In my application I need to get the hour and minute separately:

NSString *currentHour=[string1 substringWithRange: NSMakeRange(0,2)];
        int currentHour         


        

Answer 1

With iOS 8, Apple introduced a helper method to retrieve the hour, minute, second and nanosecond from an NSDate object.

Objective-C

NSDate *date = [NSDate currentDate];
NSInteger hour = 0;
NSInteger minute = 0;
NSCalendar *currentCalendar = [NSCalendar currentCalendar];
[currentCalendar getHour:&hour minute:&minute second:NULL nanosecond:NULL fromDate:date];
NSLog(@"the hour is %ld and minute is %ld", (long)hour, (long)minute);

Swift

let date = NSDate()
var hour = 0
var minute = 0
let calendar = NSCalendar.currentCalendar()
if #available(iOS 8.0, *) {
    calendar.getHour(&hour, minute: &minute, second: nil, nanosecond: nil, fromDate: date)
    print("the hour is \(hour) and minute is \(minute)")
}
