Question

if I create an object of a class, I do:

Item *item01 = [[Item alloc] init];

but how do I give it a name I have in a string? (I make this question because I have to do this in a loop, and the name of object is dynamic)

NSString *aString = [NSString stringWithFormat:@"%@", var];
Item *??? = [[Item alloc] init];

thanks!

If you want to refer the object by the name of the string, you would store your objects in NSMutableDictionary and set the key to the name.

For example:

// Someplace in your controller create and initialize the dictionary
NSMutableDictionary *myItems = [[NSMutableDictionary alloc] initWithCapacity:40];

// Now when you create your items
Item *temp = [[Item alloc] init];
[myItems setObject:temp forKey:@"item01"];
[temp release];

// This way when you want the object, you just get it from the dictionary
Item *current = [myItems objectForKey:@"item01"];
