Passing string to another view not working

Question

//FirstViewController.m

#import "EighthViewController.h"

EighthViewController *able = [[EighthViewController alloc] initWithNibName:@"EighthViewController" bundle:nil];
able.extra = @"dd"; //ERROR HERE----------------
[self presentViewController:able animated:YES completion:NULL];

//EighthViewController.h
@interface EighthViewController : UIViewController{
NSString *extra;
}

@property (nonatomic) NSString *extra;

Whenever I try and use this code (from here) I get an error in the FirstViewController saying: Property 'extra' not found on object of type 'EighthViewController *'

Another error "No visible @interface for 'EighthViewController' declares the selector 'setExtra:'" — user2649355, Aug 03 '13 at 21:09
When you're using ARC, then it should look like `@property (nonatomic, strong) IBOutlet NSString *extra;` and you have to add the @synthesize that guitarflow mentioned. — ott--, Aug 03 '13 at 21:43
Note the `IBOutlet` isn't necessary in the property definition for this use case, and `strong` is the default choice (it's implied if you don't specify it). For an NSString, [`copy` may well be a better choice than strong](http://stackoverflow.com/questions/387959/nsstring-property-copy-or-retain) anyway. — Mike Mertsock, Aug 03 '13 at 22:02

You should add that:

@property (nonatomic, retain) NSString *extra;

to your EighthViewController.h file. And add the following:

@synthesize extra;

in your EighthViewController.m file. Normally it should work then

Hope it helps

This answer is correct, but `@synthesize` is probably not necessary. – Dany Joumaa Aug 03 '13 at 23:57
