Hello!!! thanks for the blog.!! An erro is in RGBA HexToUIColor
This works OK..
a = CGFloat((hexNumber & 0xff000000) >> 24) / 255 r = CGFloat((hexNumber & 0x00ff0000) >> 16) / 255 g = CGFloat((hexNumber & 0x0000ff00) >> 8) / 255 b = CGFloat(hexNumber & 0x000000ff) / 255
Best for you!! Maximiliano Taccone
