what I want to do is change only the black color of my original image to another color, and keep for example white color of my image

what I have tried is: 

       cell.iconeEcoute?.image =     cell.iconeEcoute?.image!.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
       cell.iconeEcoute?.tintColor = colorHexIcone

But this code change the entire image color, and I want to keep green color and replace only black color in the image

any help would be appreciated

  • `UIImageRenderingMode.AlwaysTemplate` will always change the color if the alpha is 1.0. It does not matter if your color is red, black or white. Any other color that have alpha < 1.0 will be treated as transparent. – Zac Kwan Jul 11 '16 at 10:22

You can achieve it by taking separate View. Then give different color and alpha as you want. and you will see that part in different color.

  • take view as newView = UIView(frame(CGRect(size you want different in your image))) simply search on google for adding view and its property. I have example but In all cases you need different views – JAck Jul 11 '16 at 11:17
  • (size you want different in your image? , but i have more than 5 images, they dont have the same size or the same view that i want different – tamtoum1987 Jul 11 '16 at 11:32
  • is different, but i want to change only black color and keep other color – tamtoum1987 Jul 11 '16 at 11:55
  • ok.. you should try this.... take one view that covers full image and then you can set alpha with the condition that if color == black else don't change color – JAck Jul 11 '16 at 12:19
