passing data to secondViewController

Question

Trying to send some data form my previous ViewController. To be more clear trying to send the selected date of the Si-Calendar to my secondView.

I'm adding the Calendar to my view in this way:

CalendarMonth *aCalendarView = [[CalendarMonth alloc] initWithFrame:CGRectMake(0, 0, 320, 324) logic:calendarLogic];
[aCalendarView selectButtonForDate:selectedDate];
[self.view addSubview:aCalendarView];

How do I use selected date and send it to my secondViewController (a UIView in which I'll display the selected date)?

Sending an object to a view or a controller is syntactical the same. objective-c doesn't know the difference between a view and a controller. this is not an language feature but a pattern. for obj-c it is just passing an object from one object to another. so your question got answered here: http://stackoverflow.com/questions/8243266/how-to-send-a-nsdate-to-another-view — vikingosegundo, Nov 28 '11 at 11:36

It is a bit unclear what the first or second viewController is, but in general you could use a delegate for this purpose. For an example on how to do this, take a look at this answer

Add a date property to your secondViewController, and set it appropriately when you create the instance...

There are many ways to exchange data between view controllers, just take them as objects.

first controller hold a ref of the second controller, and transfer data using variables and methods
use delegate,
use notification

etc.

i can see that you are adding the CalenderMonth as the subview to another view. So if you dont release it (until u create the second view controller), you can set the selectedDate of the calender month obj to an iVar of second view controller. Else Create a delegate for CalenderMonth class. Set the second view controller as the delegate of the CalenderMonth and do the necessary.
