问题在这里。 我有一个表格, 我保存了一些数据, 我从一个NSD 词典的NSARCRRAR 中得到了这些数据, 这些数据将具有要保存的属性。 数组中的每本字典都是一个分离的实体, 所以我用插入NewObjectForEntyForEntyForName 来创建拆分实体来环绕字典并保存它 。
我需要重新显示数据, 但当保存数据时, 数据正在重复核心数据中已经存在的数据。 我试图检查核心数据上是否存在 ID 。
for(NSDictionary *exist in dic){
if([[campaignDictionary objectForKey:@"element"] isEqualToString:@"id"]){
idToCheck = [dic objectForKey:@"value"];
}
}
if(table.campaign_id == idToCheck){
return exist = YES;
}
但它留下剩下的数据没有被检查, 所以只有没有重复的 id, 任何想法 如何对待它? 谢谢!
我决定最好先从Coredata删除我的所有内容,
