And so can your app. Add AppleScriptObjC.framework to your target, and add this
to main.m:
[[NSBundle mainBundle] loadAppleScriptObjectiveCScripts];
Add a new file (choose Empty) to the project, call it SomeName.applescript, and
in it add:
script SomeName
property parent : class "NSObject"
on appVersion()
tell application "B"
set theVers to version
end tell
return theVers
end appVersion
end script
Now add an informal protocol to your calling class that includes:
- (NSString *)appVersion
And you can call it something like:
NSString *version = [NSClassFromString(@"SomeName") appVersion];
There are a few things to watch: you should only pass objects, and the bridge
only converts NSStrings/text, NSNumbers/reals/integers, NSArrays/lists and
NSDictionaries/records. And if you pass variables to the script, it needs to
coerce them to their AppleScript equivalents.
For one or two commands, ScriptingBridge might be easier. But for more complex
stuff, ASObjC avoids the whole hassle of building and maintaining the app
header file, and can do some stuff more efficiently than SBApplication et al
can.
