Add setStringValue:forExpression method on UIView #186

Open cadrega opened 4 years ago

cadrega commented 4 years ago

The setStringValue:forExpression method on UIView can set any value from a string, just like Layout does when looking at the XML attributes for a View. This expands the possibilities of the setValue:forExpression, which needs the value to be of the right type.

I updated the branch, addressing your comments. Is that the right thing to do, or should I create a new pull request?

Using this mod on Layout, I noticed two things:

I tried to set a value on a UITabBarController, but obviously it didn't work, because it's not a subclass of UIView
I tried to set a "width" value, but it's not working. The same happened using "left", but "center.x" it's working well. And again, setting "center.x" to "40%" it's not working, it only works with an absolute value.

By "not working" I mean the method has been called but no visible effect was achieved, and no error was spit out.
