我不知道我做错了什么，我也不知道如何使用 NSTimer...我只是想运行一个简单的应用程序，当您单击运行时...它会循环脚本的一部分（这就是我我试图让 NSTimer 去做，然后当你点击停止时......它停止了

到目前为止，我有这个...

current application's NSTimer's timerWithTimeInterval_target_selector_userInfo_repeats_(1, me, "runOLEDWMESerial:", missing value, yes)
on runOLEDWMESerial_(sender)
    set player_active to false
    set theString to "Error;00:00:00:00"
    tell application "Finder"
        if (get name of every process) contains "NicePlayer" then set player_active to true
    end tell
    if player_active then
        try
            tell application "NicePlayer"
                if ((count of movies) is not 0) then
                    tell front playlist
                        set theName to name
                        set curSeconds to elapsed time as integer
                        set theSeconds to duration as integer
                        set theHours to theSeconds div 3600
                        set theSeconds to theSeconds - theHours * 3600
                        set theMinutes to theSeconds div 60
                        set theSeconds to theSeconds - theMinutes * 60
                        set theDuration to ""
                        if theHours > 0 then
                            if theHours < 10 then set theHours to "0" & theHours
                            set theDuration to theHours & ":"
                        end if
                        if theMinutes < 10 then set theMinutes to "0" & theMinutes
                        if theSeconds < 10 then set theSeconds to "0" & theSeconds
                        set theDuration to theDuration & theMinutes & ":" & theSeconds
                        set curHours to curSeconds div 3600
                        set curSeconds to curSeconds - curHours * 3600
                        set curMinutes to curSeconds div 60
                        set curSeconds to curSeconds - curMinutes * 60
                        set curTime to ""
                        if curHours > 0 then
                            if curHours < 10 then set curHours to "0" & curHours
                            set curDuration to curHours & ":"
                        end if
                        if curMinutes < 10 then set curMinutes to "0" & curMinutes
                        if curSeconds < 10 then set curSeconds to "0" & curSeconds
                        set curTime to curTime & curMinutes & ":" & curSeconds
                        set theString to theName & ";" & curTime & ";" & theDuration
                    end tell
                end if
            end tell
        on error errmsg
            set theString to "Error2;00:00;00:00"
        end try
    end if
    textName's setStringValue_(theName)
    textTime's setStringValue_(curTime & "/" & theDuration)
end runOLEDWMESerial_

是的，我确信我的代码很丑陋，但本质上这将通过串行端口发送数据，这是这里的主要目标，但是现在我只是想让窗口回显正在播放的内容......

因此，runOLEDWMESerial 与运行按钮相关联...当您单击运行按钮时，循环会触发一次，但随后会停止...如果我在 runOLEDWMESERIAL_(sender) 上的所有内容中添加重复并延迟（1）它可以工作，但在用户界面中也变得无响应，我无法阻止它......所以有人可以帮助我理解为什么 NSTimer 不起作用

我实际上想通了...我有它的反语... runOLEDWMESerial_ 是按钮...但是如果您这样做...我还必须删除 try 部分，因为它不允许它正常工作

on ClickButton_(sender)
    current application's NSTimer's timerWithTimeInterval_target_selector_userInfo_repeats_(1, me, "runOLEDWMESerial:", missing value, yes)
end Clickbutton_
    on runOLEDWMESerial_()
    set player_active to false
    set theString to "Error;00:00:00:00"
    tell application "Finder"
        if (get name of every process) contains "NicePlayer" then set player_active to true
    end tell
    if player_active then

        tell application "NicePlayer"
            if ((count of movies) is not 0) then

                    set theHours to theSeconds div 3600
                    set theSeconds to theSeconds - theHours * 3600
                    set theMinutes to theSeconds div 60

                    set theDuration to ""
