How to load a sprite via WWW on IOS?

Texture 2D temp = new Texture2D(0,0);
WWW www = new WWW(pathtofile); //“pathtofile” references to a .png file.
yield return www;
temp = www.texture;
sprite = Sprite.Create(temp, new Rect(0,0,temp.width, temp.height), new Vector2(0.5f,0.5f));

Why this code works on OS X, but it doesn’t on IOS?
When i try to load this sprite on OS X - it seems ok, but on IOS i see a small question mark.
Could someone explain me - why?

And this on the other hand works on IOS but is awfully slow:

byte[] imgdata = System.IO.File.ReadAllBytes(pathtofile);
temp.LoadImage(imgdata);
sprite = Sprite.Create(temp, new Rect(0,0,temp.width, temp.height), new Vector2(0.5f,0.5f));

Btw - if i am correct the core of the problem is the texture format - but I have no idea how to work around that. I’ve also tried www.LoadImageIntoTexture(temp) but to no avail.

I have also noticed that the code to load sprite via WWW returns ARGB32 format, but on IOS its RGB24 and the sprite doesn’t show. What can I do with this?

Okay, I’ve found out, that my problem was indeed path. I’ve copied my old code and for IOS i had a different path - cuz for System.IO.File u dont need “file://” and for “www” u do need it, so to summarise: I’ve added “file://” at the start, and everything is ok.
I just didnt thought it might be the problem, cuz there were no exceptions, and i didnt catch any nulls from the function output.
