Save NSTextView in NSMutableArray and read it

Question

Hi Everyone!

My question is the following,

I have an NSTextView and I want to do 2 things :

• First save this textview in an NSMutableArray and assign a X,Y position to it in this array.

• Secondly, get this textview from the NSMutableArray and display it at the position I've set when I saved it in the array.

Anyone have an idea of how do to such things ???

Thank you very much in advance for your answer and if possible give me an example or sample code to do this in xcode.

Bye ! Robin

Answer 1

First save this textview in an NSMutableArray …

Why?

… and assign a X,Y position to it in this array.

NSArrays aren't two-dimensional; they are one-dimensional, and that dimension is numeric and sequential (i.e., valid indexes are only 0 ≤ idx < count, and existing indexes will change if an object at a lower index is removed).

To map a point to an object, you would need to wrap the point in an NSValue object and use that as the key in a dictionary.

Secondly, get this textview from the NSMutableArray and display it at the position I've set when I saved it in the array.

Again, why? It sounds almost like you're trying to reinvent nibs.
