how do i use if buttons to trigger if statements in xcode? - ios

Question

So i am creating a tic tac toe game (user vs computer) and i want to have -(IBAction) statements with if statements thats would say if(buttonIsPressed), do ____. I cant just say
-(IBAction)button:(id)selector;{
//stuff i want
}
because the buttons are pressed in different order and the computer would have different responses (i want there to be an order). For example, this is what i tried,
-(IBAction)move2;{
if (buttona2){
c2.image = [UIImage imageNamed:#"imgres-3.jpg"];
}
it didnt work because the the result of this if statement ( c2.image = [UIImage imageNamed:#"imgres-3.jpg"];) would start automatically and not run depending on the pressing of the button (it runs right away). Pretty much i want the if statement to run on press of a button (or not work if the button is not pressed.
Can anyone help?

If I understand your question right, you want to check if a button is toggled on or off before running the if statement right? In that case, I would declare a BOOL in your header file
#property BOOL toggle;
Then in your implementation file when the user presses the button the target of the button should have the code:
if(self.toggle == TRUE){
self.toggle = FALSE;
//and any visual UI change you want to show that the button is now off
}else{
self.toggle = TRUE;
//and any visual change you want to show that the button is now on
}
Then in your -(IBAction) your code becomes:
-(IBAction)move2;{
if (self.toggle){
c2.image = [UIImage imageNamed:#"imgres-3.jpg"];
}
}
And that should work.
