Ios 字典数组还是带数组的字典？
这是我的php页面中的json。这是一系列的字典，还是仅仅是一本有钥匙的字典？我认为这是第二种选择，但我不确定，因为我得到了相互冲突的选择。一旦结构显示在xcode调试器中，它还会改变吗Ios 字典数组还是带数组的字典？,ios,json,nsarray,nsdictionary,nsjsonserialization,Ios,Json,Nsarray,Nsdictionary,Nsjsonserialization,这是我的php页面中的json。这是一系列的字典，还是仅仅是一本有钥匙的字典？我认为这是第二种选择，但我不确定，因为我得到了相互冲突的选择。一旦结构显示在xcode调试器中，它还会改变吗 { "slots": { "2012-08-31 00:00:00 America/Los_Angeles": [ { "isPending": false, "isReservable": true

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

例如，要访问第二个元素的isPending属性：

您可能会发现在这里使用NSLog进行调试很有用
假设您想知道您的类是NSArray、Dictionary还是其他类。一旦您传递了JSON数据。要想知道你得到了什么，只需注销它
[NSLog(@" JSON data is kind of class %@", [NSStringFromClass([jsonData Class]);
这将告诉您json数据是什么类
如果下一项是字典或类似的数组，也可以使用相同的方法来确定
[NSLog(@" JSON data is kind of class %@", [NSStringFromClass([[jsonData objectAtIndex:i]Class]);
