There are two options available storing and retrieving data in different view controllers.

1)NSUserDefaults is best option for storing data and accessing in any other view controllers.

The NSUserDefaults class provides convenience methods for accessing common types such as float, double, integer, Boolean. A default object must be a property list, that is, an instance of (or for collections a combination of instances of): NSData, NSString, NSNumber, NSDate, NSArray, or NSDictionary.

This is very easy and best method for storing and retrieving data.

if you want to read about NSUserDefaults, here i am sharing document.

2) You would create properties when you want them to be accessible outside the class or other view controllers.

Create property in this way. @property (nonatomic, retain) NSArray *arrayData; and then you can use this array value in other view controllers also.

Properties replace the accessor methods for objects.
