Segmented Control- Change label text in another view - ios

Question

I have 2 views 1) ViewController and 2)ViewController2.
In the first view controller I have some lablels that when I run the segment controller the names change. All I want to do is, in (Viewcontroller2) where I have a label, I want it to be able to change the text as well based on the segmented controller being 0 or 1. Here is what I have.
// ViewController.h
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController{
IBOutlet UISegmentedControl *Lang;
IBOutlet UIButton *Run;
IBOutlet UILabel *bet;
}
-(IBAction)ChangeLang:(id)sender;
#end
Then in the m file i have the following to change the data
// ViewController.m
#import "ViewController.h"
#import "ViewController2.h"
#interface ViewController ()
#end
#implementation ViewController
-(IBAction)ChangeLang :(id)sender {
if (Lang.selectedSegmentIndex==0)
{
bet.text=#"Apple";
Run.titleLabel.text=#"Banana";
//not sure here what code to put in order to make the label in viewcontroller2 change.
}
if (Lang.selectedSegmentIndex==1) {
bet.text=#"ORANGES";
Run.titleLabel.text=#"FRUITS";
//not sure here what code to put in order to make the label in viewcontroller2 change.
}
}
This runs fine... heres what I have in VIEWController 2
// Viewcontroller2.h
#import <UIKit/UIKit.h>
#interface ViewController2 : UIViewController
IBOutlet UILabel *Nextword;
#end
In the M controller i just have this
#import "ViewController2.h"
#import "ViewController.h"
#interface ViewController2 ()
#end
How would I, when I run the segmented controller, make the uilabel text change in the ViewController2? Can anyone help? I dont want the screen to go to viewcontroller automatically, I was able to do that. I want the text to change, and then when i swipe to go there, i want the text in Viewcontroller2 to be according to the if statement based on the segmented controller.
Thank you

You need to have an access to instance of ViewController2 from ViewController.
Use this code inside your ViewController.h file:
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController{
IBOutlet UISegmentedControl *Lang;
IBOutlet UIButton *Run;
IBOutlet UILabel *bet;
ViewConstroller2 * VC2;
}
-(IBAction)ChangeLang:(id)sender;
#end
When you're creating instance of ViewController2 store it in VC2 variable.
Then use this code as your UISegmentedControl change event:
-(IBAction)ChangeLang:(id)sender {
if (Lang.selectedSegmentIndex==0)
{
bet.text=#"Apple";
Run.titleLabel.text=#"Banana";
VC2.Nextword= "YOUR_WORD";
}
if (Lang.selectedSegmentIndex==1) {
bet.text=#"ORANGES";
Run.titleLabel.text=#"FRUITS";
VC2.Nextword= "YOUR_WORD";
}
}
