UIView scale to 0 using CGAffineTransformMakeScale

Question

Is it possible to scale a UIView down to 0 (width and height is 0) using CGAffineTransformMakeScale?

view.transform = CGAffineTransformMakeScale(0.0f, 0.0f);

Answer 1

There are lots of times when the underlying frameworks need to invert your transform matrix. The inverse of a matrix is some matrix M' such that the product of your matrix M and the inverse matrix M' is the identify matrix 1.

1 = M * M'

The zero matrix does not have an inverse, hence the error message.
