+1 A:

You don't need to create a new NSDate object, you can just use the one it gives you.

NSDate *chosenDate = myDatePicker.date;

I want to get multiple dates from the picker, so I think I need to create multiple object and then insert those dates in the NSMutableArray.

You can just do `[array addObject:myDatePicker.date]` whenever you want to add a date.

jtbandes 2010-07-24 20:20:21

But somehow the object I inserted is out of scope. My guess is myDatePicker.date will not be returned the new NSDate object every time...

sza 2010-07-24 20:25:54

Yes, myDatePicker.date gives you the date it's set to. What do you mean it's out of scope? Can we see some code?

You probably didn't initialize the array with enough capacity via `arrayWithCapacity`

iWasRobbed 2010-07-24 21:01:58

No, `arrayWithCapacity` is just a suggestion for the array, you can still add more objects.

+1 for using dot syntax correctly.

Answer 2

+1 A:

If you really need to create a new NSDate object, then you may call [[myUIDatePicker date] copy].

There's no mutable NSDate, so there's really not a reason to do this..

jtbandes 2010-07-24 20:31:42

Create new NSDate object from the date returned from UIDatePicker
