使用NSAppleScript創建並調用Objective C中的AppleScript應用程序具有不同的結果和相同的代碼？

Question

首先，我已經創建了下面的代碼一個AppleScript應用程序（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類來調用它，如下面的代碼：

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，但它有一個問題：如果我想在另一臺計算機上運行我的APP，我需要將UserName和MyPASSWORD更改爲其他人的「UnloadTest.scpt」文件，這很愚蠢！所以我想走另一條路：用「 - （ID）initWithSource：（的NSString *）源代碼」功能，從代碼中創建一個AppleScript，我可以從我的應用程序接口發送用戶名&密碼：

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]; 

但它對我來說工作失敗，看起來像

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

不工作成功。我認爲這是AppleScript沒有獲得特權，但我不知道如何糾正它。

有沒有人可以幫助我理解這個問題？

我找到了導致此問題的原因，只是在AppleScript代碼行後面缺少「\ n」。下面的代碼是成功的：

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]; 

謝謝大家！
