Answer 1

More than likely you only simply need to add a line that says:

@property (retain) NSString * mCallNumber;

to your "contactsViewController" .h file.

B.T.W., Objective C best practices are to capitalize the first character of a Class name and keep the first character of all variables lower case. So instead of "contactsViewController", call it "ContactsViewController".

Answer 2

Try this and see if it works.

@property(nonatomic,retain) NSString *mCallNumber;
