Mac 使用Objective-C和AppleScript脚本交互

新建Xcode工程，选择macOS平台，选择Other类型中的AppleScript App。
在工程中找到appleScript后缀文件，在applicationWillFinishLaunching_方法中添加测试代码，此处以Safari为例。

on applicationWillFinishLaunching_(aNotification)
	-- Insert code here to initialize your application before any files are opened
    	--Safari打开网页
        tell application "Safari"
            activate
            --新建tab页，传入URL
            tell front window
                --get every tab
                --get URL of tab 1
                make new tab with properties {
     URL:"https://www.apple.com.cn"}
            end tell
        end tell
end applicationWillFinishLaunching_

编译运行后回在控制台报错：*** -[AppDelegate applicationWillFinishLaunching:]: Not authorized to send Apple events to Safari. (error -1743)
是因为App还没有获取到发送AppleScript事件的用户权限，所以不能直接控制Safari打开网页，在Xcode工程中的info.plist中添加Privacy - AppleEvents Sending Usage Description，后面添加上描述，再次启动就会弹出授权弹框。

最终AppDelegate.applescript文件完整示例代码

script AppDelegate
	property parent : class "NSObject"
	
    -- 载入OC类
    property Test : class "Test"
    
	-- IBOutlets
	property theWindow : missing value
	
	on applicationWillFinishLaunching_(aNotification)
		-- Insert code here to initialize your application before any files are opened
        
        --Safari打开网页
        tell application "Safari"
            activate
            --新建tab页，传入URL
            tell front window
                --get every tab
                --get URL of tab 1
                make new tab with properties {
     URL:"https://www.apple.com.cn"}
            end tell
        end tell
       
        -- 测试OC和AppleScript方法互相调用
        Test's testListParaMethod() --测试OC给脚本方法传数组参数
        Test's testDictParaMethod() --测试OC给脚本方法传字典参数
        Test's testNOParaMethod() --测试OC给脚本不传参数
        set theParaStr to get Test's testRetrunParaMethod() as text --测试通过OC方法获取返回值
        log theParaStr & " "  & (class of theParaStr) --打印返回值及类型
        
	end applicationWillFinishLaunching_
	
	on applicationShouldTerminate_(sender)
		-- Insert code here to do any housekeeping before your application quits 
		return current application's NSTerminateNow
	end applicationShouldTerminate_
	
end script
