iOS NSDictionary index value?????

[AbhishekApple]

The arry has value as==>
arry = 1~Below - $0.99,2~$1.00 - $1.99,3~$2.00 - $2.99,4~$3.00 - Above;

i want NSDictionary to be filled with above values in sequential order (ASC/DSC) with key value pair...
but the ordering is not proper!!!!!!!!!!!


Also Checkout the index value of NSDicitonary why are they not incrementing by 1 like 0,1,2,3,4....

- (void)requestFinished:(ASIHTTPRequest *)request
{
	
NSString *responseString = [request responseString];
NSArray *arry;
arry= [responseString componentsSeparatedByString:@","];
for (int i=[arry count]-1; i>=0; i--) {
NSArray *arryValue = [[arry objectAtIndex:i] componentsSeparatedByString:@"~"];
[dictPrice setObject:[arryValue objectAtIndex:1] forKey:[arryValue objectAtIndex:0]];
}
}

the Log file shows following
count=4

when i=3;

Printing description of dictPrice:

To put it simply, an NSDictionary is not sorted.

You need to use an NSArray (or NSMutableArray) to get things stored in order. If you want key/value pairs you need to encapsulate the data within a class. Once you've done that you can even use NSMutableArray sortUsingSelector to order the results if you need to.

can u give example on this....

how to create instance of class dynamically, and later use it?

like here if i want 10 instance i can define it statically but how to define dynamically so that later i can get the instance name to fetch its variables

ClassName *obj[10];

I don't have the time to give you a detailed example, but try searching Google for NSMutableArray. You should be able to find plenty of help there.
