reading passed data from view controller - ios

Question

I've got 2 view controller,
i want to pass data between them, in the first view controller i use this method to switch to other view controller and passing data :
- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView
user:(id<FBGraphUser>)user {
NSString *userName = [user username];
NSString *userId = [user id];
dashBoardViewController *dashBoardViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"dashBoardViewController"];
dashBoardViewController.first_name = userName;
dashBoardViewController.id = userId;
[self presentModalViewController:dashBoardViewController animated:YES];
}
having this on view controller.h
#interface ViewController : UIViewController <FBLoginViewDelegate>
#property (weak, nonatomic) IBOutlet FBLoginView *loginButton;
#property (weak, nonatomic) IBOutlet UIButton *showEvent;
#property (weak, nonatomic) IBOutlet UIButton *goQrcode;
#property (retain, nonatomic) NSString *id;
#property (retain, nonatomic) NSString *first_name;
in the second view controller i have this method to read the variable and switch to another view controller:
- (IBAction)gotoEvents:(id)sender {
events *events;
events.first_name = _first_name;
events.userid = _id;
[self.storyboard instantiateViewControllerWithIdentifier:#"events"];
[self presentModalViewController:events animated:YES];
}
and this on my header file:
#property (nonatomic, retain) NSString *first_name;
#property (nonatomic, retain) NSString *id;
- (IBAction)gotoEvents:(id)sender;
it says me
property 'first_name' not found on object of type 'events'

Answer 1

Try this,
events *events = [self.storyboard instantiateViewControllerWithIdentifier:#"events"];
events.first_name = _first_name; //class name Should Start With capital letter and should use camel case for naming.
events should be named as Events, as it the class name
