Touch sensing in SK game does not pick up touchEnded

UPDATE: for every request. I got NSLogged [[event touchesForView:self.view] count]

and touches count

and got the result 2

and 1

when it crashes, so it seems like the event is lost somehow

Here's my two simple methods: (updated)

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    for (UITouch *touch in touches) {
        CGPoint touchLocation = [touch locationInNode:self];


        if (touchLocation.x < self.size.width / 2.0f) {
            NSLog(@"left");
            touching = YES;
        }

        if (touchLocation.x > self.size.width / 2.0f) {
            NSLog(@"right");
            if (![rocketFlame parent]) {
                [self fireRocket];
            }
        }
    }  
}

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
        for (UITouch *touch in touches) {
    NSLog([[event touchesForView:self.view] count]);
    NSLog([touches count]);


        CGPoint touchLocation = [touch locationInNode:self];

        if (touchLocation.x < self.size.width / 2.0f) {
            NSLog(@"left off");
            touching = NO;
        }

        if (touchLocation.x > self.size.width / 2.0f) {
            NSLog(@"right off");
            //do nothing
        }
    }
}

      

        
        
        
      

    

The problem is I am getting an error where the game does not sense the end touch on the left side of the screen. I'm not sure if this error can also affect the right side of the screen, since this action is only performed once and is not a continuous action, so I wouldn't notice if it didn't feel like a completed touch.

Basically, if I touch at the same time and end my touches at the same time, it works fireRocket

and changes touching

to YES

, but then never changes touching

to NO

, even if both fingers are off.

Here's the log output:

right
left
2
1
right off
