Question

I know this is just a fundamental question but still somewhere I am missing something, I am playing with passing data to a textView from another class. For this I have created two classes one with xib file (ViewController) and another without(secondVC).

What I am trying to do is that I have a textview in ViewController class and wanted to pass the data to this textView from secondVC. This is how I am doing.

//ViewController.h

#import <UIKit/UIKit.h>
#import "secondVC.h"

@interface ViewController : UIViewController{

    IBOutlet UITextView *textView;
}

@property (nonatomic, retain) UITextView *textView;

- (IBAction)go:(id)sender;

@end


//ViewController.m

- (IBAction)go:(id)sender{

    secondVC *sec = [[secondVC alloc] init];

    [sec print];

}


//secondVC.h

#import <UIKit/UIKit.h>
#import "ViewController.h"

@interface secondVC : UIViewController

- (void)print;

@end


//secondVC.m

- (void)print{

    NSString *printThis = @"This works";

    ViewController *vc = [[ViewController alloc] init];

    [vc.textView setText:printThis];

    //vc.textView.text = printThis  //Tried both
}

Any suggestions would be appreciated.

Thanks

you can do like this :

//ViewController.h

#import <UIKit/UIKit.h>
#import "secondVC.h"

@interface ViewController : UIViewController{

    IBOutlet UITextView *textView;
}

@property (nonatomic, retain) UITextView *textView;

- (IBAction)go:(id)sender;

@end


//ViewController.m

- (IBAction)go:(id)sender{

    secondVC *sec = [[secondVC alloc] init];
    sec.viewController = self;
    [sec print];

}


//secondVC.h

#import <UIKit/UIKit.h>
#import "ViewController.h"

@interface secondVC : UIViewController {
ViewController *viewController;

}

@property(nonatomic, retain)ViewController *viewController;

- (void)print;

@end


//secondVC.m

@synthesize viewController;

- (void)print{

    NSString *printThis = @"This works";
    self.viewController.textView.text = printThis ; 
}
