I want to assign a value at index 2 of an NSArray to a NSString variable 'shoppingCart' The property shoppingCart is already declared in the ViewController.h file
#import "UIViewController.h"
@interface ViewController : UIViewController
@property (strong, nonatomic) NSString *shoppingCart;
@property (strong, nonatomic) NSArray *shoppingList;
@end
#import "ViewController.h"
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.shoppingList = [[NSArray alloc] initWithObjects: @"toothpaste", @"bread", @"eggs", nil];
self.shoppingCart = [shoppingList objectAtIndex:2];
}
@end

57,712 PointsHI there,
I think you need an additional self
in there!
self.shoppingList = [[NSArray alloc] initWithObjects:@"toothpaste", @"bread", @"eggs", nil];
self.shoppingCart = [self.shoppingList objectAtIndex: 2];
There was a similar query yesterday on this thread.
Hope that fixes it for you!
Steve.
