iOS Getting a view's scale

[fladnag]

I want to read the scale of a view into a variable but I only know how to read a view's pixel size in. Like this:

int viewWidth = myView.frame.size.width;

Can anyone tell me how to do it the other way, so that I can set a float with the view's scale - .90 or 2.50 or such?

float viewScale = myView. ??? scale??

Do you mean the scale set by a transform-matrix? If you mean that, it is possible to get the values by getting the transform-matrix and reading the appropriate fields. (I hope I remember correctly that there are 2 fields for scaling)

Exactly, see CGAffineTransformMakeScale method in documentation to see which fields you need to read.
