I am searching for a image class which is mutable.
As you know NSArray is not mutable and NSMutableArray is mutable.
Apple Documentation about UIImage
Image objects are immutable, so you cannot change their properties after creation.
What I want is to change the color of an image after creation.
How is it possible?
You can use Core Image to tap into the image's bitmap and apply a filter and then render a new image.
More specifically, you can create a custom subclass of CIFilter to apply a custom filter to your image and render it.
Unfortunately, there are many things that you'll need to do to accomplish this, including having to write some kernel code & testing it in QC, declaring a new interface, writing a couple of methods, registering and finally creating a factory method. It's a lot of stuff, but, well, it is what it is.
See the Core Image Programming Guide and the Core Image Filters Reference.
