我们如何将来自 UI 的用户输入发送到命令行和运行使用 objective c 的命令

Question

我想重置我的 MAC OSX 密码，为此我想要一个 GUI。为此，我知道在终端中我们必须运行以下命令。

  Aug4-2:~ root# passwd
  Changing password for root
  New password:
  Retype new password:

为此我想提供一个用户界面，用户可以在其中重置用户密码。我们需要使用 NStask 和 NSpipe 来完成这个任务。如果有人有代码片段，请在此处post

尝试使用苹果脚本。

tell application "System Events"
    activate
    display dialog "Please enter your old Password:" default answer "" with title "Password Reset" with hidden answer
    set the PSWD0 to text returned of the result
end tell
tell application "System Events"
    activate
    display dialog "Please enter a new password:" default answer "" with title "Password Reset" with hidden answer
    set the PSWD1 to text returned of the result
end tell
tell application "System Events"
    activate
    display dialog "Please Re-enter a new password:" default answer "" with title "Password Reset" with hidden answer
    set the PSWD2 to text returned of the result
end tell
if PSWD1 = PSWD2 then
    if PSWD1 = PSWD0 then
        display dialog "Both passwords entered are same" with title "Password Reset"
    return

    end if
else
    display dialog "Re entered Password is different" with title "Password Reset"

    return
end if
try
    do shell script "dscl . -passwd  /Users/$User  " & quoted form of PSWD0 & "       " & quoted form of PSWD1 & " "

on error errMsg number errorNumber

    if 10 = errorNumber then
        display dialog "Old password entered is incorrect" with title "Password Reset"

        return
    else
        if 90 = errorNumber then
            display dialog "New password is not meeting password policy requirements, Password length is too small" with title "Password Reset"

            return
        else
            if 93 = errorNumber then
                display dialog "New password is not meeting password policy requirements ,It should consist of atleast one Numeric character" with title "Password Reset"

                return
            end if
        end if
    end if
    return
end try
display dialog "password is changed succesfully" with title "Password Reset"
return true
