After adding the key value pairs in NSMutableDictionary, when i retrive the key/values from it, will that retrived key/value be removed from NSMutableDictionary? or is it stil maintained in NSMutableDictionary?
If you are using objectForkey to retrieve the value, the key/value will stay in the dictionary. If you would like to remove an object for a particular key from the dictionary, you need to use removeObjectForKey .
除非您调用removeObjectForKey或类似的名称,否则它将保留在那里。
