Question

How to make UITextView scrolling when text is not vertical?

Like

      +--------------+
     / Text         /
    / Here         /
   / Is           /
  / Not          /
 / Vertical     /
+--------------+

Where starts of lines are in the same angle as border (background) image.
Or we can use another element than UITextView if it can solve the problem.

Scrolling only in vertical direction,
Background image is fixed,
No, visible is only part which fits to shape, other is hidden

You can skew the textfield by using this code:

float angle = -20.0/180*M_PI;
CATransform3D skew = CATransform3DIdentity;
skew.m21 = tanf(angle);
textField.layer.transform = skew;

EDIT: perhaps I’ve misunderstood your question- you want straight text, but oblique scrolling? If that’s the case, you can put your UITextField (or UITextView) into a UIScrollView, but give the scrollView the opposite transform to your textField, like so

float angle = -20.0/180*M_PI;
CATransform3D skew = CATransform3DIdentity;

skew.m21 = tanf(-angle);
scrollView.layer.transform = skew;

skew.m21 = tanf(angle);
textField.layer.transform = skew;
