iOS Alternating a score

[Verbal CA]

Hey all,

I'm pretty new to this iPhone coding gig so apologies if this is a bit of a newbie question!

So here is the problem:

I have 2 players - Player 1 and Player 2. At any one point I want one of them marked as 'Active'. Then I have two buttons - the first button 'point' gives one point to whichever player is 'active'. The other button 'endturn' swaps the active player and gives the new active player a point. To explain that better:
- Player 1 is active - he wins and so I press 'point' and Player 1 gets the point
- On the next round Player 2 wins so I press the 'endturn' button instead. That gives Player 2 a point and makes Player 2 active. Now if the 'point' button is pressed Player 2 should get the points.

So far I have defined the two buttons and two score labels, and I can get the buttons to score each player separately, but I can't seem to figure out how to declare a player as 'active' and therefore make the points button give points to them. Any thoughts? I'm guessing I need to define a variable called 'active' and use some kind of if statement to check if 'active' is set to player 1 or 2, and then get the points button to write to the appropriate score, and then define a separate function which swops the active variable to the other player - the problem is I'm not exactly sure how to do that!

Any help would be greatly appreciated!

Well if you are looking for instruction on how to define a variable like that:

int active=1; //Starts with player one being "active"

in your header (.h) file. Then, your class (.m) file may look like this:

-(IBAction)addpoints{
if(active==1){
//Player one is active...

}
else{
//Player 2 is active

}

}

-(IBAction)endturn{

if(active==1){
active=2; //Player 1 is active, so make player 2 active...
}
else{
active=1; //Player 2 is active, so make player 1 active...

}

Hope that helps!
