How to check if two NSDates are from the same day [duplicate]
NSCalendar has a method that does exactly what you want actually!
/*
This API compares the Days of the given dates, reporting them equal if they are in the same Day.
*/
- (BOOL)isDate:(NSDate *)date1 inSameDayAsDate:(NSDate *)date2 NS_AVAILABLE(10_9, 8_0);
So you'd use it like this:
[[NSCalendar currentCalendar] isDate:date1 inSameDayAsDate:date2];
Or in Swift
Calendar.current.isDate(date1, inSameDayAs:date2)
You should compare the date components:
let date1 = NSDate(timeIntervalSinceNow: 0)
let date2 = NSDate(timeIntervalSinceNow: 3600)
let components1 = NSCalendar.currentCalendar().components([.Year, .Month, .Day], fromDate: date1)
let components2 = NSCalendar.currentCalendar().components([.Year, .Month, .Day], fromDate: date2)
if components1.year == components2.year && components1.month == components2.month && components1.day == components2.day {
print("same date")
} else {
print("different date")
}
Or shorter:
let diff = Calendar.current.dateComponents([.day], from: self, to: date)
if diff.day == 0 {
print("same day")
} else {
print("different day")
}
