I initialised the array, but the program said it is wrong because I have to initialize

What i have to change?

THViewController.h 
#import "UIViewController.h"
#import "UILabel.h"

@interface THViewController : UIViewController

@property (nonatomic, strong) IBOutlet UILabel *quoteLabel;
@property (strong, nonatomic) NSArray *quotes;
@end
THViewController.m 
#import "THViewController.h"

@implementation THViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    // Add your code below! 
    // Remember the array property is called 'quotes'
    // And the label property is called 'quoteLabel'
  NSArray *quotes = [[NSArray alloc]initWithObjects: @"Haters gonna hate", @"Life is simple, not easy",@"Winners never quit, quitters never win", nil];    

   self.quoteLabel.text = [self.quotes objectAtIndex:0];
}

@end

Hi Miguel,

Currently your simply creating a new array and assigning it to the local scope rather than using the quotes property assigned to the class which you can access via self.

self.quotes = [[NSArray alloc] initWithObjects:@"Haters gonna hate", @"Life is simple, not easy", @"Winners never quit, quitters never win", nil];

Also your objectAtIndex method call should reference the second item which is at index 1.
