variable name with value of int i

Question

i try made something like this:

for (int i=0; i<8; i++) {
    UIButton *btn_i = [[UIButton alloc] initWithFrame:CGRectMake(0 * numberRowsOfMenu, 0 * heightOfRow, btnWidth, btnHeight)];
}

where UIButton *btn_i is btn_ + value of i.

it is possible in Obj-C?

Your not going to get much milage out of these calculations `0 * numberRowsOfMenu, 0 * heightOfRow` — Paul.s, Dec 13 '11 at 18:22

Do you mean you want to wind up with variables with names like btn_0, btn_1, etc?

No, you cannot do this. You might be better off with something like this:

NSMutableArray *buttons = [[NSMutableArray alloc] initWithCapacity:8];
for(int i=0; i<8; i++) {
    UIButton *b  = [[UIButton alloc] initWithFrame:...];
    [butttons addObject:b];
    [b release];
}

// Now you can access the buttons array with indices, e.g:
UIButton *b = [buttons objectAtIndex:4];

variable name with value of int i
