我从Jason URl那里得到了一些医生的数据。该数据显示了一些医生的单一医生位置，并显示了一些医生的多个位置。我该如何显示该数据。一旦plaese给我解决方案，数据显示在下面

我正在给一个帽子代码，一旦plaese检查出来。
- offC = [[[rr objectForKey:@"doc_offices"]
objectAtIndex:0]objectForKey:@"office_name"];
NSString *docOfficeID
= [[[rr objectForKey:@"doc_offices"]objectAtIndex:0]objectForKey:@"office_id"];
答案 0 :(得分：2)
这是我的解决方案：
NSError *jsonParsingError = nil;
NSMutableArray *arrDoctorInfo = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers|NSJSONReadingAllowFragments error:&jsonParsingError];
for (NSMutableDictionary *data in arrDoctorInfo) {
NSMutableArray *arrOffice = [data valueForKey:@"doc_offices"];
NSString *strID = [data valueForKey:@"ID"];
.
.
NSString *strdoc_profile_url = [data valueForKey:@"doc_profile_url"];
for (NSMutableDictionary *dictDoffice in arrOffice) {
NSString *strdictDoffice = [dictDoffice valueForKey:@"office_id"];
.
.
NSString *stroffice_combined_name = [dictDoffice valueForKey:@"office_combined_name"];
}
}
答案 1 :(得分：0)
为什么每个人都建议使用第三方框架？ iOS具有本机JSON序列化工具：NSJSONSerialization。这非常容易使用。例如：
dispatch_queue_t fetchQueue = dispatch_queue_create("nameOfYourQ", NULL); //here i create dispatch for connection (do not block UI!)
dispatch_async(fetchQueue, ^{ // block to fetch and parse
NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://yourlink"]]; // NSData - connection for JSON
id arrayOrDictionary = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil]; // parse NSData object to Dictionaries and Arrays.
dispatch_async(dispatch_get_main_queue(), ^{
[yourTableView reloadData]; // reload your view on main thread.
});
});
这是一个非常简单的例子。我想要做的是使用NSURLConnectionDelegate下载数据，然后在委托方法中使用NSJSONSerialization来解析数据。
等等，在您的JSON结构中，您有多个doc_offices个密钥。所以我认为你真的有（获得office_id）
数组 - 字典 - 字典 - 数组。
所以：
NSNumber *docOfficeID = [[[[rr objectAtIndex:0] objectForKey:@"doc_offices"] objectAtIndex:0] objectForKey:@"office_id"];
这不是NSString。这是NSNumber
