Counter Problem

[Mr.Abe90]

I have this simple number counter app "+" to add one, "-" to subtract one.
My problem is when I press the "+" button the number will subtract by one, then if i press it again it will begin to work like it's supposed to.

Here is my code:

int count = 0;

-(void)awakeFromNib {
	
	current_number.text = @"0";
	
}

- (IBAction)add1 {
	
	if(count >= 99) return;
	
	NSString *numValue = [[NSString alloc] initWithFormat:@"%d", count++];
	current_number.text = numValue;
	[numValue release];
}

- (IBAction)subtract1 {
	
	if(count <= -99) return;
	
	NSString *numValue = [[NSString alloc] initWithFormat:@"%d", count--];
	current_number.text = numValue;
	[numValue release];	
}

What's the problem?

Simple fix would be to add a case for if count == 0. Set count = 1.

You are using postfix notation.

int i = 0 ; // i = 0
int j = i ++ ; // j = 0, i = 1
int k = ++ i ; // k = 2, i = 2

Ok sorry it was someone else's code.

Change from "count++" and "count--" to "++count" and "--count".
