我正在为Pebble制作一个非常简单的射箭场分数跟踪应用程序，我遇到了在会话之间存储和检索整数值的问题。存储和检索的行为工作正常，但由于某些奇怪的原因，只检索了1个值，然后填入第二个变量，因此它们都是相同的。
粘贴我的完整代码，包括我的调试日志记录，同时试图找出它。即使卸载窗口，所有值都是正确的，但是当在下一个窗口加载时检索值时，它似乎只得到1 ......？

我尝试使用数据结构代替保存和检索这些值，但在我的生活中无法弄清楚这是如何完成的。 Pebble开发站点上的示例没有填充到足以让我填写空白。对于像这样的事情，仍然只是一个爱好编码器所以可能有一大堆基础知识，我在这里完全没有。非常感谢任何帮助！
答案 0 :(得分：0)
想出来。我将键值误解为您要保存到存储器的整数，而不是值存储在存储器中的位置的实际键值。所以每次我保存并检索它所保存的值，并根据当时的值从不同的位置检索。
查看下页的Persist Counter代码示例对我有所帮助 https://developer.pebble.com/examples/
