在 Pebble 上读写持久数据
Reading and writing persistent data on Pebble
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，但在会话之间存储和检索整数值时遇到问题。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，然后将其填充到第二个变量中，因此它们都是相同的。
粘贴我的完整代码，包括我在尝试弄明白时的调试日志记录。即使在卸载 window 时所有值都是正确的，但是在下一次 window 加载时检索值时，它似乎只得到 1... ?

我尝试使用数据结构来保存和检索这些值，但我终究无法弄清楚这是如何完成的。 Pebble 开发站点上的示例不够详细，我无法填补空白。对于这样的事情仍然只是一个爱好编码器所以可能有一大堆我在这里完全缺少的基础知识。非常感谢任何帮助！
想通了。我将键值误解为您想要保存到存储中的整数，而不是值在存储中所在位置的实际键值。因此，每次我保存和检索值时，它都会根据当时的值从不同的位置保存和检索。
查看下一页中的 Persist Counter 代码示例对我有所帮助
https://developer.pebble.com/examples/
相关代码如下
#define NUM_TOTAL_DEFAULT 0
#define NUM_TARGETS_DEFAULT 0
#define NUM_TOTAL_PKEY 1
#define NUM_TARGETS_PKEY 2
...
static void persistValues() {
persist_write_int(NUM_TARGETS_PKEY, targets);
persist_write_int(NUM_TOTAL_PKEY, total);
}
...
static void init(void) {
// SET PERSISTENT VALUES IF EXISTS
total = persist_exists(NUM_TOTAL_PKEY) ? persist_read_int(NUM_TOTAL_PKEY) : NUM_TOTAL_DEFAULT;
targets = persist_exists(NUM_TARGETS_PKEY) ? persist_read_int(NUM_TARGETS_PKEY) : NUM_TARGETS_DEFAULT;
...
}
static void deinit(void) {
// SAVE VALUES IN TO PERSISTENT STORAGE
persistValues();
window_destroy(window);
}
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，但在会话之间存储和检索整数值时遇到问题。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，然后将其填充到第二个变量中，因此它们都是相同的。
粘贴我的完整代码，包括我在尝试弄明白时的调试日志记录。即使在卸载 window 时所有值都是正确的，但是在下一次 window 加载时检索值时，它似乎只得到 1... ?

我尝试使用数据结构来保存和检索这些值，但我终究无法弄清楚这是如何完成的。 Pebble 开发站点上的示例不够详细，我无法填补空白。对于这样的事情仍然只是一个爱好编码器所以可能有一大堆我在这里完全缺少的基础知识。非常感谢任何帮助！
想通了。我将键值误解为您想要保存到存储中的整数，而不是值在存储中所在位置的实际键值。因此，每次我保存和检索值时，它都会根据当时的值从不同的位置保存和检索。
查看下一页中的 Persist Counter 代码示例对我有所帮助 https://developer.pebble.com/examples/
相关代码如下
