how do I set an existing NSDate
's time?
That is I have a date (say current date/time), but then want to set this to a specific time (e.g. 11.23am) say. What is the quickest way to do this in objective C?
I'm looking at NSCalendar
and see methods such as dateByAddingComponents:toDate:options:
, and dateFromComponents:
, but these don't seem to quite hit the mark for what I need here. For example:
dateFromComponents:
- I would have to work out all components for this to work which seems like overkilldateByAddingComponents:toDate:options:
- I don't want to ADD in my case but rather "set" the time.NSDate *date = [NSDate date];
NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar];
NSDateComponents *components = [gregorian components: NSUIntegerMax fromDate: date];
[components setHour: 7];
[components setMinute: 59];
[components setSecond: 17];
NSDate *newDate = [gregorian dateFromComponents: components];
I use NSUIntegerMax
instead of specific OR-combined bit masks because it's easier, but if you want to specify which data components to receive, be my guest.
