  • m just giving you the idea logic is upto you:- you can use for loop and inside that separate the strings with $ and store two values into different arrays then you'll be able to have access on whatever value you want. – D-eptdeveloper Oct 15 '13 at 11:33
  • use NSDictionary for key value pairs – Atul Oct 15 '13 at 13:24

A NSDictionary can be used as a hash map and the syntax is very simple. A NSDictionary literal is declared using @{ } and can contain a comma-seperated list of key-value pairs. These key-value pairs are declared as key: value.

For example:

NSDictionary *dict = @{ @"1": @"Indore", @"2":@"Lyallpur", ... };

EDIT: To convert the string array (let's call it values) in the original question to a NSDictionary, you'd do this:

NSMutableDictionary *dict = [NSMutableDictionary dictionary];
for (NSString *value in values) {
    NSArray *keyValuePair = [value componentsSeparatedByString:@"$"];

    [dict setObject:keyValuePair[1] forKey:keyValuePair[0]];
}

Use this NSDictionary below:-

//Add how many elements you want to add on your array
    NSDictionary *yourDict=[NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:@"$Indore", nil] forKeys:[NSArray arrayWithObjects:@"1", nil]];
    NSString *yourStr=[yourDict objectForKey:@"1"];
    NSLog(@"%@",yourStr);
