I had some code like this
pInfo.orientation = NSPaperOrientationPortrait;
where pInfo is of type NSPrintInfo*. When compiling with
-Wunguarded-availability, I got a warning saying that
NSPaperOrientationPortrait is only available on macOS 10.9 and later.
So I wanted to change it to:
if (@available( macOS 10.9, * ))
{
pInfo.orientation = NSPaperOrientationPortrait;
}
else
{
pInfo.orientation = NSPortraitOrientation
}
But then I get an error, "assigning to NSPaperOrientation from
incompatible type NSPrintingOrientation". If I fix the error by adding
a typecast to NSPaperOrientation, then I get a warning that
NSPaperOrientation is only available on 10.9 and later. Is there any
way out of this roundabout, other than using a later deployment target?
