Creating a Data Collection Code Challenge Unsolved :-(

Can anyone help me with this code challenge? http://teamtreehouse.com/library/ios-development/build-a-simple-iphone-app-2/creating-a-data-collection/create-an-nsarray-property

It says: Now it's time to display a quote from our 'quotes' array in the 'quoteLabel'. Assign the second item from the 'quotes' array to the text property of the 'quoteLabel'. Hint: use the 'objectAtIndex' method.

Here is the code:

#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] initWithObjects: @"Haters gonna hate", @"Life is simple, not easy", "Winners never quit, quitters never win", nil];
  self.quoteLabel.text = [self.quotes objectAtIndex:1];
}
@end

I am having problem only with the last line of code that should assign the second item from quotes to quoteLabel. text. The Challenge won't accept it. What am I doing wrong and how should I solve this challenge?

How do I initialise it with NSStrings?

The third string "Winners never quit.." should be prefixed with an @ symbol otherwise the compiler will not know you are creating an NSString object. It will think you are trying to create a C character array which is not the same thing.

Tricky bug! Though if this was in Xcode there would've been a warning. Your bug is actually on the previous line. Check your array initWithObject. Are you initializing it with NSStrings?
