Question

I’m trying to access some things from another viewcontroller (iOS).

I have my ViewController.h:

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController <UITextFieldDelegate> {
    ...
}

@end

ViewController.m:

#import "ViewController.h"
#import "ViewController2.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad
{
   ViewController2.someVar = @"cakes"; // this is where I'm trying to set something in vc2
}

ViewController2.h:

#import <UIKit/UIKit.h>

@interface ViewController2 : UIViewController <UITableViewDataSource, UITableViewDelegate, UISearchDisplayDelegate>
{
   ...
}

@property (nonatomic, copy) NSString *someVar;

@end

ViewController2.m:

#import "ViewController2.h"

@interface ViewController2 ()

@end

@implementation ViewController2

@synthesize someVar;

etc.

But at the line where I try to access this var, it gives me the following error:

Property ‘someVar’ not found on object of type ‘ViewController2’.

In what way would I achieve accessing this other view controller?

Answer 1

You have to create a ViewControlle2 object in your Viewcontroller.m.

ViewController2 *myVC2 = [[ViewController2 alloc] initWithNibName:@"ViewController2" bundle:nil];
myVC2.someVar = @"cakes";
