Question

How do i find and remove the key value pairs of a particular key using CFMutableDictionaryRef.
I have added a value using CFMutableDictionary but i need to know how to search ,view and delete a keyvalue pair.
The value i have created is a structure pointer and key is an integer value.

Answer 1

Beata,

The CFMutableDictionaryRef documentation shown Here will guide you.

In the order of your question:

For finding an element, see CFDictionaryGetValue

For removing an element, see CFDictionaryRemoveValue

Note that the CFDictionary types are a ‘toll-free-bridge’ with NSDictionary.
