Answer 1

i dont think you need to set your button's x and y here. just set the tag of your buttons, say tag 1 - 4, generate random number 1 - 4 (possible tag of your buttons), save your buttons to NSArray and do a loop like:

NSArray *buttonsArr = [[NSArray alloc]initWithObjects:button1,button2, button3, button4, nil];
int randomInt = (arc4random() % 4) + 1;
for (int i = 0; i < [buttonsArr count]; i++) {
    if ([(UIButton*)[buttonsArr objectAtIndex:i] tag] == randomInt) {
        [[buttonsArr objectAtIndex:i] setTitle:@"correct" forState:UIControlStateNormal];
    }else{
        [[buttonsArr objectAtIndex:i] setTitle:@"wrong" forState:UIControlStateNormal];
    }
}
