    “(” = parentheses, “[” = brackets, “{” = braces. That would make your video a lot easier to follow.

    Instead of repeating what you write you should explain the concepts and relationships between the objects in the project. Thanks

    This is a great tutorial, but i have a few errors that i don’t know how to fix..

    The line at 5.20, says ‘redefinition of ‘- [CalculatorViewController buttonOperationPressed:] ‘
    and
    The line at 8.10-8.20, the error is ‘NSStringWithFormat is ‘undeclared’ what does this mean?

    Thanks for any help mate :)

    Loads perfectly but I do not get input on the screen (e.g. I press 9+9=, the 0 remains there)
