Try this:

NSDictionary *student1 = [NSDictionary dictionaryWithObjectsAndKeys:
                          @"key1", @"id",
                          @"Joe", @"name",
                          nil];

NSMutableArray *array = [NSMutableArray arrayWithObjects:student1, nil];

NSMutableArray *mArr = [[NSMutableArray alloc]init];
for (NSDictionary *student in array) {
    [mArr addObject:[student objectForKey:@"name"]];
}
NSArray *arr = mArr;
NSLog(@"%@",arr);    //OUTPUT: (Joe)
