i find out what was wrong the catsgame code was only running when there was a winner because it ws connected with if and the brakets where all closing after it HERE is the right way:

-(void)processLogic{
//The process Logic will check for a win, if one is present it will present
//a UIAlert. If one is not found it will display a Draw message if all the spaces are filled.

if([self checkForWin]){
if(playerToken==1){
myAlertView = [[UIAlertView alloc] initWithTitle:@"Winner!" message:@"Player X wins!" delegate:self cancelButtonTitle:@"Ok." otherButtonTitles:nil];
[myAlertView show];

[self resetBoard];
}
if(playerToken==2){
myAlertView = [[UIAlertView alloc] initWithTitle:@"Winner!" message:@"Player O wins!" delegate:self cancelButtonTitle:@"Ok." otherButtonTitles:nil];
[myAlertView show];

[self resetBoard];

}
}else{
if(numberOfPlays == 8){
myAlertView = [[UIAlertView alloc] initWithTitle:@"No Winner!" message:@"It's a cats game!" delegate:self cancelButtonTitle:@"Ok." otherButtonTitles:nil];
[myAlertView show];

[self resetBoard];


}
}


}

Hey Im a completely NOOB... i have an error in the tic tac toe app, When I put this:

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
//The error is in Switch an it sais "Switch Quantity, not an Integer" really i don't //have any idea, help please
	switch (PlayerToken){
		case 1:
			TheImg = XImg;
			break;
		case 2:
			TheImg = OImg;
			break;
	}

BTW, the tutorial is very very good, it was helpful. Thank you.

Sweet, did you use the displayWinner method? or did you code something else?

[bvawter]

make sure your decarations in the .h file are correct:

//new variable for the images added
IBOutlet UIImage * theImg;

//integer that represents the player
NSInteger playerToken;
NSInteger numberOfPlays;
}
@property (nonatomic,retain) UIImage *theImg;//new
@property (nonatomic,retain) UIImage *oImg;
@property (nonatomic,retain) UIImage *xImg;

I just finished my first tictactoe game and the computer player is quite "smart". May be you can have a look at how I did it?

At high level:
1) build an array storing status of each of the 8 possible rows (3xhorizontal, 3xvertical, 2xcross) that could win
2) update status at each move
3) based on score work out the most critical one
4) add a few extra "special" conditions which the logic couldn't handle

For further info, please see this post on my blog. Full source code also available.
