Answer 1

您的数据位于Array（字典集合）

所以，首先从Array＆amp;获得Dictionary。然后将特定字典的键添加到新数组（这是日期的结果数组）

试试这个，

NSArray *arrData;

NSMutableArray *arrDates = [NSMutableArray array];

for (NSDictionary *dict in arrData) {

    [arrDates addObject:[[dict allKeys] firstObject]];
}

NSLog(@"Dates :: %@", arrDates);

希望，它会帮助你。

Answer 2

外部对象是一个数组，第0项包含两个字典。

NSDictionary *dictionary = array[0];

然后枚举字典并提取date值

NSMutableArray *dates = [NSMutableArray array];
for (NSString *key in dictionary) {
   [dates addObject: dictionary[key][@"date"]];
}

如何从数组中获取日期值？
