How can I convert an NSDictionary to an NSMutableDictionary?

Question

I have an existing NSDictionary that has:

{
    \"charts_count\" = 2;
    \"created_at\" = \"2010-04-12T16:37:32Z\";
    exchange = NASDAQ;
    \"followers_c         


        

Answer 1

NSMutableDictionary *newInfo = [[NSMutableDictionary alloc] init];
[newInfo setDictionary:info];

Also works, since you are setting the dictionary not appending. You can also use:

[newInfo addEntriesFromDictionary:info];

for the same effect and to append to existing content.
