Чтение и запись постоянных данных на Pebble

Question

Чтение и запись постоянных данных на Pebble

Я делаю очень простое приложение для отслеживания оценки поля стрельбы из лука для Pebble, и у меня возникают проблемы с хранением и получением целочисленных значений между сессиями. Процесс сохранения и извлечения работает нормально, но по какой-то странной причине извлекается только 1 значение, а затем заносится во вторую переменную, чтобы они оба были одинаковыми.

Вставка моего полного кода, включая запись в журнал отладки при попытке выяснить это. Все значения верны даже при выгрузке окна, но при получении значений при следующей загрузке окна, кажется, просто получается 1...?

Вместо этого я пытался использовать структуры данных для сохранения и извлечения этих значений, но пока не могу понять, как это делается. Пример на сайте разработчиков Pebble недостаточно продуман, чтобы я мог заполнить пробелы. Все еще только хобби-программист для подобных вещей, так что, вероятно, есть целая куча основ, которые мне здесь просто не хватает. Любая помощь очень ценится!

Догадаться. Я неверно истолковал значение ключа как целое число, которое вы хотите сохранить в хранилище, а не как фактическое значение ключа для места, где оно хранится. Поэтому каждый раз, когда я сохранял и извлекал значения, которые он сохранял и извлекал из разных мест, в зависимости от того, какое значение было в то время.

Глядя на пример кода Persist Counter на следующей странице, мне помог https://developer.pebble.com/examples/

Соответствующий код сейчас

#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);
}
