**试图为我的应用程序使用GPS.ane并且我一直收到错误

“第55行，第50列1120：访问未定义的属性onClickStop。”

这是令我头疼的线路我认为我错过了一些小但我无法找到它。您会认为该应用程序会给出您所在位置的纬度和经度。谢谢你的帮助**

Answer 1

stopBtn.addEventListener（TouchEvent.TOUCH_TAP，onClickStop）;

公共函数onClickstop（evt：TouchEvent）：void {

您的功能在停止时具有较低的大小写，但是当您引用它时，您使用大写S.

认为这一切都是错误的

GPS.ane为我的应用程序，我一直收到错误第55行，第50列1120：访问未定义的属性onClickStop
