Re: using constants from Obj-c in swift

2015-09-25 Thread Boyd Collier 
Charles & Marco,

Thanks very much for the prompt replies.  I think I’d tried 
scrollView.borderType = .NSNoBorder (and lots of other things), but didn’t 
think of leaving off the “NS”.

I had one of those. Apple would send out updates - “please replace page X with

Arrgh... typo

> scrollview.borderType = NoBorder

That should be 

scrollview.borderType = .NoBorder

of course.  How come I never see that kind of thing until AFTER I hit send.

Swift will replace an accessor like setFoo with direct access to the property 
foo.  For your case the documentation for setBorderType says the swift version 
is

var borderType: NSBorderType

If you then look at NSBorderType you’ll see this:

enum NSBorderType : UInt {
case NoBorder
case LineBorder
case BezelBorder
case GrooveBorder
}

> Is there a straightforward way to do this?  (I’m using swift 2 in Xcode 7)

Translating [scrollview setBorderType:NSNoBorder]; to swift is

scrollview.borderType = NoBorder


After doing this a few times the pattern will become pretty obvious and you’ll 
need to go to the doc less and less.

Generally speaking, Objective-C enums get simplified in Swift so that the 
common prefixes are removed from the name of the constant. You access an enum 
by typing the enum type name, then a period, then the constant name (in your 
case, NSBorderType.NoBorder). However, if you have a property or parameter that 
is defined as that enum type, you can leave the enum type name out, and the 
compiler will infer it. So, all you have to do is this:

scrollView.borderType = .NoBorder

using constants from Obj-c in swift

2015-09-25 Thread Boyd Collier 
In objective-c programs, there are places where one can write lines like the 
following:

[scrollview setBorderType:NSNoBorder];

with NSNoBoarder being specified in an enum in NSView.  But enums in swift are 
a different sort of beast, and I’ve not yet figured out what get the same job 
done.
Is there a straightforward way to do this?  (I’m using swift 2 in Xcode 7)

FWIW before the nice hardcover books there was a single (as I recall) loose 
leaf binder with documentation for the 128K.
