Re: Trouble with passing variables

Try putting *number in parentheses before using the increment operator, like this (*number)++. I think your problem is that the increment operator, ++, when postfixed has higher precedence than the indirection operator. That is, number, which is the address of where you have stored the value of the int that you are interested in, is incremented, and then when the indirection operator is applied, you get whatever value is stored at that (incremented) address, which is likely to be garbage. I've not tested this, but I'm reasonably sure that this is your problem.

Ok I am trying something like the following:

-(BOOL)numberAdded:(int*)number
{
	*number++;
	return YES;
}

-(void)addNumber
{
	int flct = 0;

	[self numberAdded:&flct];

	NSLog(@"%i",flct);
}

and basically it is not adding one to the number. How do I pass a pointer to an integer so that I can modify it in another function? I thought I had it right but clearly I do not.
