Question: Assume we're creating an app that tells us random quotes. We have a label in our view that's connected to a ViewController.h file using an IBOutlet. We also have a button connected to a quoteButtonPressed:(id)sender action. When we tap the button, we want to show the user a quote. Assign the string "A stitch in time saves nine." to the quoteLabel.
Code:
#import "UIViewController.h"
#import "UILabel.h"
@interface ViewController: UIViewController
@property (strong, nonatomic) IBOutlet UILabel *quoteLabel;
- (IBAction)quoteButtonPressed;
quoteLabel.text = "A stitch in time saves nine."
@end
#import "ViewController.h"
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)quoteButtonPressed {
//Add your code below!
}
@end

You have the correct code but not in the correct spot as you have it declared it in your interface instead of your implementation file for the quoteButtonPressed @IBAction.
- (IBAction)quoteButtonPressed {
self.quoteLabel.text = @"A stitch in time saves nine.";
}
Hope that helps.

- (IBAction)quoteButtonPressed { quoteLabel.text = "A stitch in time saves nine." }
