我遇到上述json，并且关键节点可能随时更改，请建议我如何解析其节点随时动态更改的json?

I am having the above json and key node may change at any time pls suggest me how can I parse a json whose node is changing dynamically at any time ???

推荐答案

使用Ehab Amer指出的框架. 对于解析，您可以使用此代码段最简短

Use the framework as pointed by Ehab Amer. For parsing you can use this code snippest

SBJsonParser *sbjasonObj=[[[SBJsonParser alloc]init] autorelease];
NSMutableDictionary *categoriesContainer = [[NSMutableDictionary alloc]initWithDictionary:[sbjasonObj objectWithString:result]];

其中结果为JSON.
