Question

If I want get one Label.text from View1,
so I set in firstView.h

@interface RootViewController : UITableViewController {
 NSMutableArray *menuList;
}
@property(nonatomic,retain)NSMutableArray *menuList;

@end

---

in secondView.h

@interface SecondViewController : UIViewController <UIPickerViewDelegate,UIPickerViewDataSource> {

 UILabel *comboView;

}
@property (nonatomic,retain)UILabel *comboView;
@end

---

in secondView.m

FirstViewController *firstViewController = [[FirstViewController alloc]initWithNibName:@"FirstViewController" bundle:nil];
[firstViewController.menuList addObject:comboView.text];

---

but when I want to get object from menuList in firstView(self.menuList)
It become “null”!!!

What’s the problem??
Thanks

The code provided is very limited, did you remember to initialize the ‘menuList’ before adding objects? Objective C lets you add objects to uninitialized array’s, so a mistake is easily made.
