For-loop on object names

There is probably a very simple way of doing this, but this is a programming niggle I've had for a long time but never thought there might be an answer to.

Consider the following:

[someButton1 setTitle:[NSString stringWithFormat:@"%@",[someArray objectAtIndex:0]]];
[someButton2 setTitle:[NSString stringWithFormat:@"%@",[someArray objectAtIndex:1]]];
[someButton3 setTitle:[NSString stringWithFormat:@"%@",[someArray objectAtIndex:2]]];
[someButton4 setTitle:[NSString stringWithFormat:@"%@",[someArray objectAtIndex:3]]];
[someButton5 setTitle:[NSString stringWithFormat:@"%@",[someArray objectAtIndex:4]]];
[someButton6 setTitle:[NSString stringWithFormat:@"%@",[someArray objectAtIndex:5]]];
... etc

I know I can use a For {...} loop to provide the array indexes, but is there any way of iterating through the button names programmatically, i.e someButton1, someButton2 etc?

You can put the buttons themselves in an array and iterate over it.

There is a way, using introspection, but you don't need to, simply create an array of buttons and iterate it in the same way you iterate the array of strings...
