Question

I would like to be able to create an array with e.g 4 colors. And then use them in my tableview cells, inside cellForRowAtIndexPath. Like this:

-----------------
|      red      |
-----------------
-----------------
|      blue     |
-----------------
-----------------
|     yellow    |
-----------------
-----------------
|     green     |
-----------------
-----------------
|      red      |
-----------------
-----------------
|      blue     |
-----------------
-----------------
|     yellow    |
-----------------
-----------------
|     green     |
-----------------

And so on. I was able to do this with modulus in javascript, but in xcode/obj c I just can’t figure it out. I looked everywhere. I managed to change every second, or just total random colors.

Answer 1

you may do the following:

     if(indexPath.row %4 ==0)
     {
              cellView.backgroundColor = [UIColor redColor];
     }
     else if(indexPath.row %4 ==1)
     {
              //setBackground to be the second color
     }
     else if(indexPath.row %4 ==2)
     {
              //setBackground to be the third color
     }
     else
     {
           //setBackground to be the fourth color
     }

this way each you will get the colors repeated each four rows,
I hope this helps, good luck!
