This code challenge seems to be contradicting it self.

Can anyone figure out whats wrong?

Here is what the preview says: too many arguments to method call, expected 1, have 4

 self.quotes = [[NSArray alloc] initWithObject:@"Haters gonna hate", @"Life is simple, not easy", @"Winners never quit, quitters never win", nil];
THViewController.h 
#import "UIViewController.h"
#import "UILabel.h"

@interface THViewController : UIViewController

@property (nonatomic, strong) IBOutlet UILabel *quoteLabel;
@property (nonatomic, strong) 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'
    self.quotes = [[NSArray alloc] initWithObject:@"Haters gonna hate", @"Life is simple, not easy", @"Winners never quit, quitters never win", nil];    



}

@end

The first problem I can see is that your array declaration should be:

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

You've left the 's' off initWithObjects

This should give a different error because there is no initWithObject: function, but try this out and let us know.

i think you are missing a bracket "{}" after "@implementation THViewController <- {"

Okay Lee, fixed what you said and from what I can tell the rest is all the same, but now it (the preview) says that I'm missing the end box bracket and I'm not. Any tips?

Hi Caleb

I've gone back to the code challenge and run your code exactly as it is (with the added s) and it works - I don't get anything on the preview. It should be working now - as I say, I've copied and pasted and it runs.

If you still aren't sorted, could you post your updated code?

Not sure what was wrong, I tried it again today and it worked. Thanks!
