iOS Build a Simple iPhone App (iOS7) Creating a Data Collection Create an NSArray Property

Creating a data collection 3of3

I really thought I had this right... What's missing?

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.

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];
}

  • (IBAction)thingyThing { self.quoteLabel.text = [self.quotes objectAtIndex:1]; }

@end

Why do you have an IBAction method there? First, it is never called, thus its contents are never executed. Second, you don't need it at all - just assign the array item directly.

So, you have two ways to complete the challenge:

  1. Actually call the thingyThing method in viewDidLoad by sending a message to self:

    [self thingyThing];

  2. Get rid of the thingyThing method and simply put its contents in the viewDidLoad method.

The second way is straightforward and I assume how it is intended to be done in this challenge.
