我正在嘗試將數組保存到核心數據。我一直在評論以下主題:Storing custom objects in an NSMutableArray in NSUserDefaults(特別是Stefan的回答)。我的代碼如下:將數組保存到核心數據
for (TempWorkout *newTempWorkout in items)
{
NSString *strCounterInt = [NSString stringWithFormat:@"%d", counterInt];
newTempWorkout.temp_time = strCounterInt;
newTempWorkout.temp_route = route.text;
newTempWorkout.temp_activity = activity.text;
newTempWorkout.temp_intensity = intensity.text;
NSString *strTotalDistance = [NSString stringWithFormat:@"%.3f", totalDistance];
newTempWorkout.temp_distance = strTotalDistance;
newTempWorkout.temp_mapID = mapID;
[[NSUserDefaults standardUserDefaults] setObject:[NSKeyedArchiver archivedDataWithRootObject:startTimeArray] forKey:@"temp_start_time"];
[self.tempWorkoutArray addObject:newTempWorkout];
}
上面的代碼工作,但是當我看着我的表(通過在瀏覽器SQLITE經理),我沒有看到鑰匙「temp_start_time」的任何值。
問候, 斯蒂芬
感謝Nick,我放棄了這種方法,只是將數組作爲字符串存儲在Core Data中。 – Stephen 2010-09-30 15:43:54
