macos - Applescript 更改山狮通知中心背景的应用程序

Question

我想创建一个应用程序来更改通知中心的背景，因此对其进行了编写。有人请告诉我我的代码有什么问题。

set NCBGPath to "/System/Library/CoreServices/Notification Center/Contents/Resources/"
set NCBackground to "linen.tiff"
set themeFolder to (choose folder with prompt "Choose a Theme") as text
set themePath to themeFolder & NCBackground
set posixNCPath to NCBGPath & NCBackground

set shouldCopy to false
tell application "Finder"
    if exists file themePath then set shouldCopy to true
end tell

if shouldCopy then
    do shell script "cp " & quoted form of POSIX path of themePath & space & quoted form of posixNCPath with administrator privileges
    -- you probably should correct the file permissions too as the copied file probably won't have the proper owner and stuff
else
    display dialog "Could not find the background file in the chosen folder."
end if

Answer 1

可能是这样的：“如果 cp 检测到尝试将文件复制到自身，则复制将失败。”

如果将最后一个 if 语句更改为：

if shouldCopy then
    do shell script "cp " & quoted form of POSIX path of themePath & space & quoted form of NCBGPath with administrator privileges
    -- you probably should correct the file permissions too as the copied file probably won't have the proper owner and stuff
else
    display dialog "Could not find the background file in the chosen folder."
end if
