Search in NSMutableDictionary only with partial key

I want to know if there is a possibility to search in an NSMutableDictionary with a开发者_开发知识库 partial key.

For Eg.: Let key be 2345 and partialkey can be 2 or 23 or 234,etc

Thanks

You can use the allKeys method to get an array of all the keys and then filter them based on your partial key.
