Question

I am going through the iOS development videos by Stanford and am doing the assignment 1.

I am having a problem with task 4:

Add a new text label (UILabel) to your user-interface which shows everything that
has been sent to the brain (separated by spaces). For example, if the user has entered
6.3 Enter 5 + 2 *, this new text label would show 6.3 5 + 2 *. A good place
to put this label is to make it a thin strip above the display text label. Don’t forget to
have the C button clear this too. All of the code for this task should be in your
Controller (no changes to your Model are required for this one). You do not have to
display an unlimited number of operations and operands, just a reasonable amount.

I have the UILabel and have done all of them. I am finding it hard on how I can do this. Any help is greatly appreciated.

(P.S. Please don’t post a full code solution as I want to learn how to do it and posting code would just render my learning pointless, any hints and pointers would be the best! Thanks).

Answer 1

You should convert your array into a string, which you can then assign to the label.

label.text = [array componentsJoinedByString:@" "];
