convert dictionary to array after removing key values - iphone

Question

i need to remove first three keys values from each index of array. What i did is
for (int i=0; i<[normalscoringarray count]; i++)
{
NSDictionary *dictionary = [normalscoringarray objectAtIndex:i];
NSMutableDictionary *mutableDictionary = [dictionary mutableCopy];
[mutableDictionary removeObjectForKey:#"cn"];
[mutableDictionary removeObjectForKey:#"gdate"];
[mutableDictionary removeObjectForKey:#"gid"];
NSLog(#"mutableDictionary.....%#",mutableDictionary);
NSMutableArray *remainingArray = [[NSMutableArray alloc]init];
for (id item in mutableDictionary) {
[remainingArray setArray:[mutableDictionary objectForKey:item]];
}
}
and it does not give remainingArray in that order i want, more over it removes all keys.

Answer 1

NSMutableArray *remainingArray = [[NSMutableArray alloc]init];
for (int i=0; i<[normalscoringarray count]; i++)
{
NSMutableDictionary *mutableDictionary = [[NSMutableDictionary alloc] initWithDictionary:[normalscoringarray objectAtIndex:i]]; //each time alloc and init with contents of normalscoringarray
//Remove values for keys
[mutableDictionary removeObjectForKey:#"cn"];
[mutableDictionary removeObjectForKey:#"gdate"];
[mutableDictionary removeObjectForKey:#"gid"];
[remainingArray addObject:mutableDictionary]; //add mutableDictionary to remainingArray
[mutableDictionary release]; //free mutableDictionary
}
//finally print contents of remainingArray
NSLog(#"normalscoringarray:\n%#",[remainingArray description]);
Hope this would be help you!

Answer 2

for (int i=0; i<[normalscoringarray count]; i++)
{
NSMutableDictionary *dictionary = [NSMutableDictionary dictionaryWithDictionary:[normalscoringarray objectAtIndex:i]];
[dictionary removeObjectForKey:#"cn"];
[dictionary removeObjectForKey:#"gdate"];
[dictionary removeObjectForKey:#"gid"];
[normalscoringarray replaceObjectAtIndex:i withObject:dictionary];
}
