Swift 3+

you can use date-components, like:

let date1 = Date()
let date2 = Date(timeIntervalSinceNow: 12345678)

let dateComponets = Calendar.current.dateComponents([.day, .hour], from: date1, to: date2)

then you can see the difference in days:

debugPrint(dateComponets.day, dateComponets.hour) // 142 (days), 22 (hours)

ObjC

same approach, but different syntax:

NSDate * date1 = [NSDate new];
NSDate * date2 = [NSDate dateWithTimeIntervalSinceNow:12345678];

NSDateComponents * dateComponents = [[NSCalendar currentCalendar] components:NSCalendarUnitDay | NSCalendarUnitHour fromDate:date1 toDate:date2 options:0];

then the difference in days:

NSLog(@"%d, %d", dateComponents.day, dateComponents.hour); // 142 (days), 22 (hours)
