从json ios检索数据

这是dictionary*数据的内容

 Data =     {
        Specialities =         (
                        {

解析方式类似于：

        NSDictionary *dataDict = [responseDictionary valueForKey:@"Data"];
        NSMutableArray *specialityArray = [dataDict valueForKey:@"Specialities"];
        NSDictionary *objectDict = [specialityArray objectAtIndex:your index (0/1/2)];
        int *speciality = [[objectDict ValueForKey:@"Speciality"] intValue];
    if(speciality = 22)
    {
        NSMutableArray *videoArray = [objectDict valueForKey:@"Videos"];
        NSDictionary *videoObject = [videoArray objectAtIndex:your index (0/1/2)];
        NSString     *videoID     = [videoObject valueForKey:@"VideoId"];
    }

---

根据需要相应地解析其余部分。

解析方式如下：

        NSDictionary *dataDict = [responseDictionary valueForKey:@"Data"];
        NSMutableArray *specialityArray = [dataDict valueForKey:@"Specialities"];
        NSDictionary *objectDict = [specialityArray objectAtIndex:your index (0/1/2)];
        int *speciality = [[objectDict ValueForKey:@"Speciality"] intValue];
    if(speciality = 22)
    {
        NSMutableArray *videoArray = [objectDict valueForKey:@"Videos"];
        NSDictionary *videoObject = [videoArray objectAtIndex:your index (0/1/2)];
        NSString     *videoID     = [videoObject valueForKey:@"VideoId"];
    }

根据需要相应地解析其余部分。

使用此代码

    NSArray *wholeArray = [[responseDictionary objectForKey:@"Data"] valueForKey:@"Specialities"];
    NSArray *subArray = [[wholeArray objectAtIndex:0] valueForKey:@"Videos"];

子数组是获取所有视频值，然后使用此代码获取单个值

NSString  *videoID = [[subArray objectAtIndex:i] valueForKey:@"VideoId"];

或者您将在单个变量中获得所有videoID，使用下面的代码

NSMutableArray *tempArray = [[NSMutableArray alloc] init];
    for (int i = 0; i < subArray.count; i++) {
        [tempArray addObject:[[subArray objectAtIndex:i] valueForKey:@"VideoId"]];
    }

希望它有用的

特性是数组，每个索引都包含一个字典。你可以对数组使用ObjectAtIndex。特性是数组，每个索引都包含一个字典。你可以对数组使用ObjectAtIndex。感谢Saad的帮助，你的代码解决了我的问题，但唯一的问题是我无法硬编码索引。NSDictionary*objectDict=[specialityArray对象索引：您的索引（0/1/2）]；你真的喜欢硬编码吗？如果我们完全确定某个值及其出现，我们通常会硬编码。这也是一种不好的做法。我不想硬编码bcoz speciality id可能会更改，因此如何获取特定speciality的索引，以便您可以重复使用您的专业：

for（NSDictionary*objectDict in specialityArray）{int*speciality=[[objectDict ValueForKey:@“speciality”]intValue]；等等。}
