定义一个单利存储数据

1.保存到沙盒的代码：http://zhidao.baidu.com/question/1754885661883506468.html?fr=iks&word=iOS+%B4%FA%C2%EB%C8%E7%BA%CE%BB%F1%C8%A1SVN%D6%D0%B5%C4%CA%FD%BE%DD&ie=gbk

//  方法+ (NSString *)getCache:(int)type andID:(int)_id{NSUserDefaults *default = [NSUserdefaults standardUserDefaults];NSString *key = [NSString stringWithFormat:@“detall-%d-%d”, type, _id];NSString *returnStr = [default objectForKey:key];return returnStr;}

2.如果沙盒里面有数据

// 处理NSString *value = [Tool getCache:5 andID:self.QiuTime]; if (value) { NSDictionary *backdict = [value JSONValue]; if ([backdict objectForKey:@"items"]) { NSArray *array=[NSArray arrayWithArray:[backdict objectForKey:@"items"]]; for (NSDictionary *qiushi in array) { QiuShi *qs=[[QiuShi alloc]initWithDictionary:qiushi]; [self.list addObject:qs]; } } [self.tableView reloadData]; // 刷新 tableView}
