If you’re using PaintCode you might want to have drawrect code that scales depending on your needs. I’m sure there are multiple ways to achieve this. I use the help of two macros I call “MyMacroForX” and “MyMacroForY” for now which translate the given float value based on the dimensions of the UIView I set in Interface Builder or code. Unfortunately PaintCode does not provide you anything to help with adding those macros to it’s generated code.

Let’s assume you have a more complex shape than a circle, multiple layer and so on. You end up pretty quickly having lots of CGPointMake calls like
CGPointMake(34.54, 87.28)

but want something like
CGPointMake(MyMacroForX(34.54), MyMacroForY(87.28))

The Solution:

Xcode offers search and replace based on regular expressions which is a great solutions if your don’t want to spent an hour copy & pasting.

Set the style in your Replace options to Regular Expression. It’s also useful to define a custom search scope for the upcoming task (if your don’t want to replace all occurrences in your project).
The find pattern I use looks like this
CGPointMake\([-+]?([0-9]*\.[0-9]+|[0-9]+), [-+]?([0-9]*\.[0-9]+|[0-9]+)\)

As replace pattern I use
CGPointMake(MyMacroForX(\1), MyMacroForY(\2))

This saved me a lot of time in the past and I’m sure it will in the future.
