Question

I need to know;

1.) how to save values to a NSDictionary, and in Key-Value pairs. I have the following keys and values to be saved to a single NSDictionary

Key —— Value

“1” ——- “One”

“2” ——-“Two”

“3” ——– “Three” etc..

2.) Later i need to save the above NSDictionary to a NSArray. Is this possible ?

3.) Is there a way to Order the above NSDictionary in Assending order. How can i do this

Answer 1

1. [NSDictionary dictionaryWithObjectsAndKeys:@"value", @"key", @"value", @"key2", nil]
2. [dict allKeys] or [dict allValues]
3. A dictionary is a map from a value to a key. Ordering does not make sense. If you get the keys from the dictionary, you can sort the values in that as you would an ordinary NSArray
