Custom UIView will allow us to modify the image chosen by the user and add some funny drawing before we share it with our friends on Facebook. To do this, we will have to store the elements added by the user. In the end, we can generate UIImage.
Such elements can be the background, a text, an image, and a shape. In this case, we are going to simplify it by creating texts with the same color and font family. There will only be one image (a hat) and the shape will always be a circle, but remember that you are free to improve this app.
