CGRect syntax I haven't seen before

Question

I saw the syntax below in some example code and am not sure I understand it.

 CGRect imageRect = (CGRect){.size = baseImage.size};

Is this simp

Answer 1

This is not just shorthand syntax but is also useful when you want to change only the size and not the origin in CGRect and vice versa.

Eg : I want to change only the size and the position has a complicated syntax and I dont want to change it. Noramlly, I would do

CGRect imageRect = CGRectMake(sprite.origin.x,sprite.origin.y,40, 60);

With the other syntax i would do

CGRect imageRect = (CGRect){.size = sprite.size};

also we can directy use add, subtract and multiply methods eg.

 CGRect imageRect = (CGRect){.size = ccpAdd(sprite.size,addsize)};

Hope this helps
