In your table view controller make an property for the array.

@interface DetailedAddViewController : UITableViewController{
    NSArray *dataSourceArray;
}
@property (nonatomic, retain)    NSArray *dataSourceArray;
@end

And in m file don't forget to add

@synthesize  dataSourceArray;

And in dealloc method to release it

[addDictionary release];

Possibly you are switching from one view controller to another.So the view controller loading again.In viewDidload method,initialize a flag and remove an array inside the flag.
