Swift NSScriptCommand performDefaultImplementation

问题

I used this code in Objective C:

@implementation KDOrderInfo
  - (id)performDefaultImplementation {
    NSString *theRequest = [self directParameter];
    NSDictionary *arguments = [self evaluatedArguments];
    NSLog(@"arguments = %@ %ld",arguments, [arguments count]);
    NSLog(@"theRequest----> %@",theRequest);
    /*.......
    .....*/
    return @YES
  }

This code works OK in Objective C. I converted this code to Swift code as follows:

class OrderInfo : NSScriptCommand {
  override func performDefaultImplementation() -> AnyObject! {
    let theRequest: AnyObject! = self.directParameter
    let arguments = self.evaluatedArguments
    println("arguments = \(arguments) argumentsCount = \(arguments.count)")
    println("theRequest----> \(theRequest)")
    /*.......
    .....*/
    return "OK"
    }
 }

when I run my applescript then I get the error (InfoMaker is the name of my app): InfoMaker got an error: The handler some object is not defined.

The method :

override func application(theApp:NSApplication,delegateHandlesKey theKey:String) -> Bool{ 
    println("scripting key = \(theKey)");
    let thekeys = ["pathToXML", "saveXMLFlag", "webserviceName","methodName","pathToInfoFiles","fileToCheck","scriptingProperties"]

    if thekeys.containsString(theKey.lowercaseString,  searchcase:NSStringCompareOptions.CaseInsensitiveSearch) {
        //[self prefsToVars];
        println("YES")
        return true;
    } else {
        println("NO")
        return false
    }
}

in my app delegate responds OK to the applescript.

I tried also with the "SimpleScriptingVerbs" example from Apple and I get the same error in my Swift implementation. I hope somebody can help find the problem and have a suggestion.

回答1:

In the meantime, I was able to find a solution to the problem and get the app working with script commands.

The cocoa class name for your command you must mention in the script definition file (.sdef) is not the same as the name of the class in XCode (Swift), as it is the case for Objective-C.

Instead you have to prepend the project name/module to the class like this: MyProject.MySwiftCommandClassName

If in doubt what the right name is, in your Swift class, you can use the following code to get the correct name to use in your .sdef file:

class func classString() -> String {
    return NSStringFromClass(self)
}

Your .sdef file may look similar to this:

<dictionary title="MyAp">
    <suite name="MyAp Suite" code="MyAp" description="MyAp Scripts">
        <command name="myCommand" code="MyApMyCm" description="...">
            <cocoa class="MyProject.MySwiftCommandClassName"/>
            [...]
