Incrementing variable names

In xcode I want to create 100 images one with the name1,2,3,4 ect. And i can do it all except for the variable names. For these I was wandering is it possible to increment the variables programmatically or whether it must be done manually?

  • Why load 100 images into memory if you could simply cache and display... 3 at a time. What exactly might you be doing? – CodaFi Jun 17 '12 at 17:55

Instead of creating a bunch of variable names, you can use a dictionary object with the names as keys and the image object as the data.

If you really want to/have to use 100 different variables and avoid an array you could use Key Value Coding in combination with a for loop: 

NSString *name = @"myVariable";
for (int i = 0; i< 100; i++)
{
    // get aValue from somewhere...
    NSString *key = [NSString stringWithFormat:@"%@%d", name, i];
    [self setValue:aValue forKey:key];
}

This sort of thing is best achieved with an array.

Create them in an NSMutableArray. Doesn't matter if all of them have the same object name, since they have different locations in the array. Just access them with [arrayName objectAtIndex:index]; Use a for.
