Question

I am making an app for the iPhone using Xcode and I think that Xcode is messing me up…
I have in the ViewController.h:

 @property (weak, nonatomic) IBOutlet UITextField *passwordField;

 @property (weak, nonatomic) IBOutlet UILabel *passwordResult;

 - (IBAction)go:(id)sender;

and in the ViewController.m:

- (void)viewDidLoad {

    A = @"A";

}

- (IBAction)go:(id)sender {

    password = [NSString stringWithFormat:@"%@", _passwordField.text];

    if (password == A) {
         _passwordResult.text = [NSString stringWithFormat:@"%@", A];
         }
   }

This should print the capital letter ‘A’ to my label if the input is a capital ‘A’, right?
If not, How would I do this?

NOTE: I do not want to just copy the inputted phrase and print that, I want to make a password cracker application just to see if it works…

Answer 1

Instead of:

if (password == A)

use

if ([password isEqualToString:A])

Otherwise, you’re only comparing pointers, not the contents of the strings themselves.
