Swift/Objective-C/Applescript 项目中无法识别的选择器

Question

当运行这个简单的 ASObjc 程序与 Swift 交互时，我收到以下消息：

 *** -[ASMyObject foo:]: unrecognized selector sent to object <ASMyObject @0x60c000226fe0: OSAID(4) ComponentInstance(0x810000)>

如果我从 foo 中删除参数，代码将按预期工作。我意识到我使用参数创建 foo 的方式一定有问题。

这是代码，基于 :

AppDelegate.swift

func applicationDidFinishLaunching(_ aNotification: Notification) {
    ASObjC.shared().myObject.foo(5)
}

ASMyObject.applescript

script ASMyObject
property parent : class "NSObject"

on foo(value)
    log value * 2
    return "Success!"
end foo

end script

ASObjC.h

@import Cocoa;
@import AppleScriptObjC;

@interface NSObject (MyObject)
    - (NSString *)foo:(int)value;
@end

@interface ASObjC : NSObject
    + (ASObjC *)shared;
    @property NSObject * MyObject;
@end

ASObjC.m

#import "ASObjC.h"

@implementation ASObjC

+ (void)initialize
{
    if (self == [ASObjC class]) {
        [[NSBundle mainBundle] loadAppleScriptObjectiveCScripts];
    }
}

+ (ASObjC *)shared
{
    static id shared = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        shared = [[ASObjC alloc] init];
    });

    return shared;
}

- (instancetype)init
{
    self = [super init];
    if (self) {
        _MyObject = [NSClassFromString(@"ASMyObject") new];
    }
    return self;
}

@end

桥接-Header.h

#import "ASObjC.h"

您必须添加一个下划线字符来表示 ObjC 中的冒号

on foo_(value)
    log value * 2
    return "Success!"
end foo

或者

on foo:value
    log value * 2
    return "Success!"
end foo

并且在您必须声明传递对象的方法的类别中，ObjC 原语不起作用。

- (NSString *)foo:(NSNumber *)value;

要在 AppleScript 端分配值，您必须强制它

on foo:value
    log (value as integer) * 2
    return "Success!"
end foo
