使用NSAppleScript创建并调用Objective C中的AppleScript应用程序具有不同的结果和相同的代码？

Question

首先，我已经创建了下面的代码一个AppleScript应用程序（文件名：UnloadTest.scpt）：

-- Set user name and password 
set UserName to "MyAccount" 
set MyPASSWORD to "MyPassword" 
-- unload FTDIUSBSerialDriver 
do shell script "sudo kextunload /System/Library/Extensions/FTDIUSBSerialDriver.kext" user  name UserName password MyPASSWORD with administrator privileges 
-- Copy driver to the used location 
do shell script "sudo cp ./libftd2xx.1.0.2.dylib /usr/local/lib" user name UserName password MyPASSWORD with administrator privileges 
do shell script "sudo cp ./libd2xx_table.dylib /usr/local/lib" user name UserName password MyPASSWORD with administrator privileges 
do shell script "cd /usr/local/lib" user name UserName password MyPASSWORD with administrator privileges 
do shell script "sudo ln -sf libftd2xx.1.0.2.dylib libftd2xx.dylib" user name UserName password MyPASSWORD with administrator privileges 

而且使用NSAppleScript类来调用它，如下面的代码：

NSString * strScript = [[NSBundle mainBundle] pathForResource:@"UnloadTest" ofType:@"scpt"]; 
NSAppleScript * appScript = [[NSAppleScript alloc] initWithContentsOfURL:[NSURL fileURLWithPath:strScript] error:nil]; 
[appScript executeAndReturnError:NULL]; 
[appScript release]; 

它可以正常工作，但它有一个问题：如果我想在另一台计算机上运行我的APP，我需要将UserName和MyPASSWORD更改为其他人的“UnloadTest.scpt”文件，这很愚蠢！所以我想走另一条路：用“ - （ID）initWithSource：（的NSString *）源代码”功能，从代码中创建一个AppleScript，我可以从我的应用程序接口发送用户名&密码：

NSString  *strScriptUnload = [NSString stringWithFormat:@"\ 
              set UserName to \"%@\"\ 
              set MyPASSWORD to \"%@\"\ 
              do shell script \"sudo kextunload /System/Library/Extensions/FTDIUSBSerialDriver.kext\" user name UserName password MyPASSWORD with administrator privileges\ 
              do shell script \"sudo cp ./libftd2xx.1.0.2.dylib /usr/local/lib\" user name UserName password MyPASSWORD with administrator privileges\ 
              do shell script \"sudo cp ./libd2xx_table.dylib /usr/local/lib\" user name UserName password MyPASSWORD with administrator privileges\ 
              do shell script \"cd /usr/local/lib\" user name UserName password MyPASSWORD with administrator privileges\ 
              do shell script \"sudo ln -sf libftd2xx.1.0.2.dylib libftd2xx.dylib\" user name UserName password MyPASSWORD with administrator privileges",[m_textUserName stringValue], [m_textPassword stringValue]]; 
    NSAppleScript *appUnloadScript = [[NSAppleScript alloc] initWithSource:strScriptUnload]; 
    returnDescriptor = [appUnloadScript executeAndReturnError:nil]; 
    [appUnloadScript release]; 

但它对我来说工作失败，看起来像

sudo ln -sf libftd2xx.1.0.2.dylib libftd2xx.dylib 

不工作成功。我认为这是AppleScript没有获得特权，但我不知道如何纠正它。

有没有人可以帮助我理解这个问题？

我找到了导致此问题的原因，只是在AppleScript代码行后面缺少“\ n”。下面的代码是成功的：

NSString  *strScriptUnload = [NSString stringWithFormat:@"\ 
             set UserName to \"%@\"\n\ 
             set MyPASSWORD to \"%@\"\n\ 
             do shell script \"sudo kextunload /System/Library/Extensions/FTDIUSBSerialDriver.kext\" user name UserName password MyPASSWORD with administrator privileges\n\ 
             do shell script \"sudo cp ./libftd2xx.1.0.2.dylib /usr/local/lib\" user name UserName password MyPASSWORD with administrator privileges\n\ 
             do shell script \"sudo cp ./libd2xx_table.dylib /usr/local/lib\" user name UserName password MyPASSWORD with administrator privileges\n\ 
             do shell script \"cd /usr/local/lib\" user name UserName password MyPASSWORD with administrator privileges\n\ 
             do shell script \"sudo ln -sf libftd2xx.1.0.2.dylib libftd2xx.dylib\" user name UserName password MyPASSWORD with administrator privileges\n",[m_textUserName stringValue], [m_textPassword stringValue]]; 
NSAppleScript *appUnloadScript = [[NSAppleScript alloc] initWithSource:strScriptUnload]; 
returnDescriptor = [appUnloadScript executeAndReturnError:nil]; 
[appUnloadScript release]; 

谢谢大家！
