Solution 1
Your question contains so many other questions, I will try to solve few of them related to converting dictionary to array.
Store all keys
NSArray *dictKeys=[dict allKeys];
Store all values
NSArray *dictValues=[dict allValues];
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]];
Solution 2
for (NSDictionary *dictionary in arrayname)
{
NSMutableArray *array = [dictionary objectForKey:@"writeKey"];
}
This might help you
