Obj-C/AppleScript 语法问题

我正在从我的应用程序内部调用 AppleScript。我的代码的相关片段如下所示：

-(void)sendMail:(NSString*)addressStr
    {
    NSString *scriptString = <snip>
    @"end tell\n"   
    @"tell b to make new to recipient with properties {address:\"[email protected]\"}\n"
    @"send b\n"
    @"end tell\n";
    <snip>
}

带有“硬连线”电子邮件地址的脚本运行完美，但我真的想使用我们社区数据库之外的地址。我尝试使用可变字符串作为 scriptString，然后在将 scriptString 传递给 AppleScript 对象之前将传递的 addressStr 插入到确切的（已知）索引处。但是，如果我删除（仅）地址字符并尝试类似的操作：

@"tell b to make new to recipient with properties {address:\"\"}\n"
<snip>
[scriptString insertString:addressStr atIndex:556];

...它要么不会编译，要么在运行时给出“尝试使用 insertString:atIndex: 改变不可变对象（??）”错误 - 取决于我尝试什么。

因此，要么我的语法错误（P=0.95），要么我试图用 AppleScript 完成不可能的任务。有人可以帮我吗？预先非常感谢:-)

原文

I'm calling an AppleScript from inside my application. The relevant snippet of my code looks like so:

-(void)sendMail:(NSString*)addressStr
    {
    NSString *scriptString = <snip>
    @"end tell\n"   
    @"tell b to make new to recipient with properties {address:\"[email protected]\"}\n"
    @"send b\n"
    @"end tell\n";
    <snip>
}

The script with "hard-wired" email address runs perfectly, but I really want to use addresses out of our community database. I tried using a mutable string for the scriptString, then inserting the passed addressStr into it at an exact (known) index before passing scriptString to the AppleScript object. But if I remove (only) the address chars and try something like:

@"tell b to make new to recipient with properties {address:\"\"}\n"
<snip>
[scriptString insertString:addressStr atIndex:556];

...it either won't compile or gives an "Attempt to mutate immutable object (??) with insertString:atIndex:" error at runtime -- depending on what I try.

So either my syntax is wrong (P=0.95), or I'm trying to do the impossible with AppleScript. Can anyone help me out, please? Thanks a lot in advance :-)
