Your question contains so many other questions, I will try to solve few of them related to converting dictionary to array.

1. Store all keys

   NSArray *dictKeys=[dict allKeys];
   

2. Store all values

   NSArray *dictValues=[dict allValues];
   

3. If you want to store both keys and values:

   NSArray *keysAndValues=[dictKeys arrayByAddingObjectsFromArray:dictValues];

EDIT:

As you require NSMutableArray, you can use :

NSMutableArray *dictAllKeys=[NSMutableArray arrayWithArray:[dict allKeys]];
NSMutableArray *dictAllValues=[NSMutableArray arrayWithArray:[dict allValues]];
NSMutableArray *keysAndValues=[NSMutableArray arrayWithArray:[dictAllKeys arrayByAddingObjectsFromArray:dictAllValues]];
