String comparison in Objective-C

I realize that the question is not very specific. I am working on a simple trivia game to test a couple of things, right now it has 5 arrays, one for the questions, one for the first answer option, one for the second answer option, one for the third, and one that says which one is correct.

I have an if statement in that checks wether the button pressed matches the correct answer.

Answer2 is connected to the button that would select option b in my trivia app, strCorrect is the string array that holds the single character that says which option out of the three is right, intCurrentQuestion is just an integer I use to reference the index of the arrays. 

-(IBAction)Answer2{
    if ([strCorrect objectAtIndex:intCurrentQuestion] == [NSString stringWithFormat:@"B"]){
        //do these things blah blah
    }
}

The problem is that there are no errors when it is compiled but it doesn't work either. How do I go about making this work?

For testing purpose I am cheating and passing the strCorrect to a hidden label in the nib and then comparing the label text to @"B" and it works but its...well its just awful.

What you're doing in your code above is comparing the memory address of two strings, not their value. Do compare two NSStrings you have to do this:

[[strCorrect objectAtIndex:intCurrentQuestion] isEqualToString:@"B"];
