这是我的php页面中的json。这是一本字典的Arrary还是只是一把字典，里面有钥匙和字典？我认为这是第二种选择，但我不确定，因为我的选项相互矛盾。一旦它在xcode调试器中显示，结构也会改变吗？

答案 0 :(得分：2)
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。键看起来像是2012-08-31 00:00:00 America/Los_Angeles。这些键包含字典数组。
答案 1 :(得分：1)
你能做的最好的事情就是尝试一下！你会比在这里要求的时间少！ 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"];
答案 2 :(得分：0)
字典周围的[和]似乎表明它是一系列字典。
或者更确切地说，Array位于Dictionary内的Dictionary内。第一段只涉及最里面的结构。
答案 3 :(得分：0)
您可能会发现在此处使用NSLog进行调试很有用。
假设你想知道你的班级是NSArray，Dictionary还是其他班级。一旦传递了JSON数据。要查看您的回复，请将其注销。
[NSLog(@" JSON data is kind of class %@", [NSStringFromClass([jsonData Class]);
这将告诉你json数据是什么类。
您也可以使用相同的方法来确定下一个项目是字典还是像这样的数组
[NSLog(@" JSON data is kind of class %@", [NSStringFromClass([[jsonData objectAtIndex:i]Class]);
但纯粹从观察中我会说你有一本词典数组词典词典
答案 4 :(得分：0)
我是这样做的。
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"]);
}
}
