NSArray quotes

Hey. Im at the NSArray quotes challenge, and I cant get it to work. I tried rewatching the video, but i cant get it to work.

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

@end

the .h file

#import "UIViewController.h"

import "UILabel.h"

@interface THViewController : UIViewController @property (nonatomic, strong) NSArray *quotes; @property (nonatomic, strong) IBOutlet UILabel *quoteLabel;

@end

The problem is in viewDidLoad. You are initializing it the way you would declare it. You can remove the NSArray and *quotes from the line and it'll work.

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

This is because you have already declared a NSArray @property named quotes in the header file. When you do this, Xcode automatically creates an instance variable named quotes, so you don't need to create it again. See this answer for more about setters, getters and properties.
