Hello,
I'm new in objective C programming. I try to do a program where a user can choose the number of partitions of a range in the code appears like "valor = 30" (number of rows in table), this range can be change from 1 to 100 only by the user, the main goal is using a NSTableView to show squares with its respective calculated value (drawing both in each cell), the total number of rows contained in the table will be manipulated by the user in "valor", but every cell must have different data. So if this program works fine, every square look like a color degradation, beginning in green, passing through brown to achieve red like maximum (you can see the image attached).
The question is how can just draw one time every cell without change values in my table view?, because every time I click outside my XCode project appears in my Log View changes and makes me think that the table's work never stops and every time change colors in my table view. Is necessary to use an scroll to check the completely squares and values on the table, it appears but not works.
I attached my controller class.
I don't know what should I do, I really appreciate some help please.
Thanks,
Priscila Jardón.
