How can I use multiple items in one if statement?

in this case, i'm using:

- (IBAction)reset:(id) sender {

if ((boxHide1.hidden = YES) && (boxHide2.hidden = YES)) {
    resetHide.hidden = NO;
}

}

How can I do this? I have 12 items all together I need in the statement. Thanks!

You could use the solution @Joe posted but as you can tell the code for hiding / unhiding could get very messy and hard to read.

If you want to keep your code clean and easy to understand / maintain, I'd put all these buttons into a NSMutableArray and iterate through it to determine whether you want to show the reset button or not.

BOOL showResetButton = YES;
for (UIButton *button in buttonsArray)
{
    if (button.hidden == NO) // If any of the buttons is not hidden do not show the reset button
        showResetButton = NO;
}
resetButton.hidden = showResetButton;

Make sure you use == to compare values but since they are already booleans you do not need to compare against YES. If all the comparisons are AND(&&) that is correct and you can drop the parenthesis, otherwise if there are any OR(||) operations then you would need to group the appropriate operations.

if (boxHide1.hidden && 
    boxHide2.hidden && 
    ... &&
    boxHide12.hidden) 
{
    resetHide.hidden = NO;
}
