I have tried everything that I'm still stuck.

If the guess is correct, we want to alert the user with a message using a UIAlertView. Add an if statement that checks if the BOOL variable 'isCorrect' is true (or 'YES'). Inside the if statement, declare a new UIAlertView variable named 'alertView'. Alloc/init it with the method 'initWithTitle:message:delegate:cancelButtonTitle:otherButtonTitles'. For the title, use "Hooray!", for the message, use "You did it!", for the delegate use nil, for cancelButtonTitle use "OK", and for otherButtonTitles use nil.

import "NumberGuesserViewController.h"

import "GuessEngine.h"

import "UIAlertView.h"

@implementation NumberGuesserViewController

  • (IBAction)makeGuess:(id)sender { NSString *userNumber = self.numberField.text;

    // Check to see if the user's number is correct BOOL isCorrect = [GuessEngine testGuess:userNumber];

if (isCorrect == true){ UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Hooray!" message:@"You did it!" delegate:nil cancelButton:@"OK" otherButtonTitles:nil];

[alertView show];} } @end

try comparing to YES instead of true:

    if (isCorrect == YES){
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Hooray!" message:@"You did it!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];

        [alertView show];

}
