Disable a gesture from firing - ios

Question

I have a tap gesture on my view that I only want to be able to fire after a certain point and after a different function has run. My solution was to create a outlet for the tap gesture and then call the Enabled function setting to TRUE or FALSE as needed. The code looks like this, with the second function being the tap gestures
- (IBAction)butt:(id)sender
{
if(game == FALSE)
{
tapges.enabled = FALSE;
int sec;
sec = arc4random() % 5;
if(sec == 0){sec++;}
sleep(sec);
tapges.enabled = TRUE;
game = TRUE;
gun.hidden = FALSE;
start = [[NSDate date] timeIntervalSince1970];
}
}
- (IBAction)tap:(id)sender
{
if(game == TRUE)
{
end = [[NSDate date] timeIntervalSince1970];
double total = end - start;
NSString *myString = [NSString stringWithFormat:#"%lf", total];
ss.text = myString;
game = FALSE;
gun.hidden = TRUE;
tapges.enabled = FALSE;
}
}
However it doesn't seem to work. Even after the first function has set tapges.enabled = FALSE if you tap before it reaches tapges.enabled = TRUE it still just queues the tap function for running after the butt function runs.

Answer 1

There is a way to prevent a UIGestureRecognizer from firing (or to call another function before it fires) through using UIGestureRecognizerDelegate method gestureRecognizerShouldBegin but I think the issue is more a question of logic.
Not sure I entirely understand your task but wouldn't something more simple like:
- (IBAction)butt:(id)sender
{
if(game == FALSE)
{
[self callOtherMethod];
}
}
Or
- (IBAction)butt:(id)sender
{
if(game == FALSE)
{
//do set up
} else {
// do other setup
}
}
