better you can initialize it in appdelegate of your project. then you can access this array anywhere in your project.

#define UIAppDelegate ((yourAppDelegate *)[UIApplication sharedApplication].delegate)

include this in your your appDelegate, then you can access your array any where you want.

UIAppDelegate.yourArray
