看看这里： http: //www.json.org/

基本上你有一个字典slots，里面有多个对象。键看起来是这样的东西2012-08-31 00:00:00 America/Los_Angeles。这些键包含字典数组。

您能做的最好的事情就是尝试一下！你会比在这里问更少的时间！无论如何，你有：

 - dictionary, with a "slot" key that has an associated value:
    - dictionary, with a "2012-08-31 00:00:00 America/Los_Angeles" key that that has an associated value:
       - array, containing objects:
          - dictionary1
          - dictionary2
          - ....

因此，例如，要访问第二个元素的 isPending 属性：

[[[[dict objectForKey:@"slot"] objectForKey:@"2012-08-31 00:00:00 America/Los_Angeles"] objectAtIndex:1] valueForKey:@"isPending"];

The [ and ] around the dictionaries seems to suggest it's an array of dictionaries.

Or rather, an Array inside a Dictionary inside a Dictionary. The first paragraph only addresses the innermost structures.

您可能会发现在此处使用 NSLog 进行调试很有用。

假设你想知道你的类是 NSArray、Dictionary 还是其他类。一旦你传递了 JSON 数据。要查看您返回的内容，只需将其注销。

[NSLog(@" JSON data is kind of class %@", [NSStringFromClass([jsonData Class]);

这将告诉您 json 数据是什么类。

您也可以使用相同的方法来确定下一项是字典还是像这样的数组

[NSLog(@" JSON data is kind of class %@",  [NSStringFromClass([[jsonData objectAtIndex:i]Class]);

但纯粹从观察来看，我会说你有一本字典数组字典

这是我的做法。

for (NSString *slotKey in myslots.allKeys) {
    NSDictionary *slot = [myslots valueForKey:slotKey];
        NSArray *tests = [myslots objectForKey:slotKey];
    for (NSDictionary *myDict in tests){
        NSLog(@"%@", [myDict objectForKey:@"begin"]); 
    }
    }
