Total newb here.
What is the difference between this
_myUIProgressView.transform = CGAffineTransformScale(_myUIProgressView.transform, 1.0, 0.3);
and this:
[_myUIProgressView setTransform:CGAffineTransformMakeScale(1.0, 0.3)];
besides the brevity. Why would you favor one over the other?
Those 2 calls are functionally identical. The only difference is syntax.
The first is called dot notation. The second is a method call to the setter.
Dot notation is an alternative way to invoke a property's setter or getter, and it does exactly the same thing as the other syntax.
Some people (mostly old school C programmers) don't like the dot syntax. I'm an old C programmer, but I like it.
