How to hide a Label and show it when a button is pressed in AppleScript app?

Question

I would like to know how to hide/show a label using AppleScript I tried something like:

property label : missing value
    if label's isHidden() = 1
                label's setHidden_(0)
            end if

but mot working.

Answer 1

To perform an AppleScript if expression you have to coerce ObjC BOOL to AppleScript boolean.
But you can pass an AppleScript boolean in the setter.

if label's isHidden() as boolean then -- is true is redundant 
   label's setHidden:false
end if
