如何解决处理参数的applescript应用程序中的“无法继续计数”问题?

当你双击它,你不会传递任何参数,所以没有什么可数的…所以它是错误的。使用try块可以避免错误。试试这个…

on run argv
    try
        set rtn to ((count of argv) as text) & " parameters passed.
The parameters were:
"
        repeat with arg in argv
            set rtn to rtn & "      " & (arg as text) & "
"
        end repeat
    on error
        set rtn to "There are no arguments to count!"
        display dialog rtn buttons {"OK"} default button 1 with icon note
    end try
    return rtn
end run
