Question

我不确定我做错了什么，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，当你点击Run ...它会循环一部分脚本（这个是我试图让NSTimer做的，然后当你点击停止...它停止

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_

是的我确定我的代码很难看，但实际上这将是通过串口发送数据，这是主要目标，但是现在我只是想让窗口回显正在播放的内容。 ..

所以runOLEDWMESerial绑定到一个运行按钮...当你单击运行按钮时，循环触发一次，但然后停止...如果我在runOLEDWMESERIAL_（发送者）的所有内容中添加一个重复延迟（1）它有效，但在ui中也没有响应，我无法阻止它......所以有人可以帮助我理解为什么NSTimer无法正常工作

Answer 1

我实际上已经明白了......我有它的后缀...... runOLEDWMESerial_是按钮......但是如果你这样做的话......我还必须删除try部分，因为它不允许它工作正常

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

    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
                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 curHours < 10 then set curHours to "0" & curHours
                        set curDuration to curHours & ":"
