Arrary的字典或词典与数组？

这是我的PHP页面中的json。这是一本词典的Arrary还是一本字典，里面有钥匙和字典？我认为这是第二种选择，但我不确定，因为我遇到了相互冲突的选择。一旦它显示在xcode调试器中，结构也会改变吗？Arrary的字典或词典与数组？

看看这里：http://www.json.org/

基本上你有一本字典slots这里面有多个对象。键看起来像是这样的东西2012-08-31 00:00:00 America/Los_Angeles。这些键包含字典数组。

谢谢，这更有意义。 – TIDev

的[和]周围的字典似乎表明这是字典的数组。

或者说，内的Dictionary内的Array。第一段只涉及最内层的结构。

你可以做的最好的事情就是尝试一下！你会比在这里要求更少的时间！ 总之有：

- 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，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"];

键是一个字典数组，所以你的代码将无法工作。 – TIDev

你可能会发现，在这里使用NSLog的调试。

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。要查看您回来的内容，只需注销即可。

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

这会告诉你你的json数据是什么类。

你也可以用同样的方法来acertain如果下一个项目是一个字典或类似这样的

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

一个数组，但单纯从观察，我会说你有字典

正确，插槽是字典，键是NSArray，现在我必须进入每一天dictionary- objectAtIndex：我说未声明的变量 – TIDev

这是我做到的。

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"]); 
    } 
    }
