I am not clear about your code but if you want to send string from class1 to class2 then you can follow below method:

1.Declare property in class2, same as you have declare:

NSString * string1;
@property(nonatomic, retain)NSString * string1;

@synthesize string1;

2.Then in class1 where you are navigating to class2 (from where you are initializing class2) just assign your string1 the required value as follows:

class2Obj.string1 = @"Hi";

and In class2 you can access string1.
