Comparing two UITextFields

I have no idea why this isn't working and I feel it's something really very stupid.. I'm trying to compare two textfields (like a confirming the password type of thing) but it just isn't working!! Ive tried several different options and none of them work. I've tried:

if (passwordCheckField1.text == passwordCheckField2.text) {
        [self performSegueWithIdentifier:@"segue4" sender:nil];
    }

I've tried:

NSString *retrivedPasswordCheckField1 = passwordCheckField1.text;
NSString *retrivedPasswordCheckField2 = passwordCheckField2.text;
if ([retrivedPasswordCheckField1 isEqualToString:retrivedPasswordCheckField2]) {
        [self performSegueWithIdentifier:@"segue4" sender:nil];
    }

I've tried:

if ([passwordCheckField1.text isEqualToString:retrivedPasswordCheckField2.text]) {
        [self performSegueWithIdentifier:@"segue4" sender:nil];
    }

I've implement the <UITextFieldDelegate> in the .h and i've also set the delegates for both fields, (passwordCheckField1.delegate = self; passwordCheckField2.delegate = self;)

What am I missing???? Thanks for your help!

EDIT

I probably should mention that I'm using a Navigation Controller, with several child view controllers. Each contains a text field, so when the view controller about the first password comes up, the user enters it and then clicks next taking them to the confirm password view controller. All are linked to the same class files.

As a precautionary measure, try triming both the password strings for leading and trailing spaces before comparing like

NSString *pwd1 = [pwdTxtField1.text stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@" "]];

This should work.

NSString *password = passwordCheckField1.text;
NSString *confirmPassword = passwordCheckField2.text;

NSLog(@"password: '%@'", password);
NSLog(@"confirmPassword: '%@'", confirmPassword);

if([password isEqualToString: confirmPassword]) {
       NSLog(@"Match");

} else {
        NSLog(@"Not Match");

}

try this

if([[passwordCheckField1 text] isEqualToString:[passwordCheckField2 text]])
{
    [self performSegueWithIdentifier:@"segue4" sender:nil];
}
else
{
   //not matched
}

chk your values. 

 if ([passwordCheckField1.text isEqualToString:passwordCheckField2.text]) {   
    //Match it's working for me 
 }

if (passwordCheckField1.text == passwordCheckField2.text) {
    [self performSegueWithIdentifier:@"segue4" sender:nil];
}

The above code doesn't compare two string values. It actually compares two pointers value.So it is not going to be useful for you.

but code

if ([retrivedPasswordCheckField1 isEqualToString:retrivedPasswordCheckField2]) { [self performSegueWithIdentifier:@"segue4" sender:nil]; }

should have compared the string values. May be string your values are not same or nil. Have you printed the passwordCheckField1.text and passwordCheckField2.text.What is the values for two strings ?
