If statement expecting ]

if (menuPlayed == TRUE && [sender tag == 0]) {
    NSLog(@"You're pressing the right button at the right time");
}

Any idea why this is throwing up a "Expected "] "" error? I have absolutely no idea what's wrong with those comparisons :(

Change:

if (menuPlayed == TRUE && [sender tag == 0])

to:

if (menuPlayed == TRUE && [sender tag] == 0)

Also note that you should never write expressions such as menuPlayed == TRUE - always write this as just menuPlayed, i.e. in this particular case:

if (menuPlayed && [sender tag] == 0)

And as mentioned in @rokjarc's answer, you might want to add some parentheses for clarity, although these are not actually required:

if (menuPlayed && ([sender tag] == 0))

Change your code to:

if ((menuPlayed == TRUE) && ([sender tag] == 0))

And you'll probably have to typecast sender, something like

if ((menuPlayed == TRUE) && ([(UIButton *)sender tag] == 0))

Ofcourse you shouldn't just use (UIButton *) for typecast. Use the correct class of your sender object or use one of it's ancestor classes. I believe 'tag' is added to UIView in this object hierarchy.
