Question

Answer 1

You can do like:

For example: you want to pass Array from FirstViewController to SecondViewController.

Create Array in SecondViewController first and define it as property as in SecondViewController.h:

NSMutableArray *secondArr;
@property (nonatomic, retain) NSMutableArray *secondArr;

In SecondViewController.m:

@synthesize secondArr;

Then, for example, you want to pass Array when a button in FirstViewController is touched. In its action (create IBAction, link it with the button's touchesUpInside), you can set it to get the instance of your second view controller, for example:

secondViewController.secondArr = firstArr;
