您的数据在数组中（字典的集合）
因此，首先从数组中获取字典，然后将特定字典的键添加到新数组中（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);

外部对象是一个数组，项0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"]];
}
