Problems with Multi-Touch

[LukasBanana]

Hi everybody, I'm new here and I don't know if this is the right sub-forum.
I have some problems with the multi-touch for iOS. I thought "touchesBegan" from the UIView will always be called when a new finger touches the screen.
But it don't. It only occurs when the first finger touches the screen and "touchesEnded" occurs when the first finger releases the screen.
But I want to know when a new finger touches the screen. I don't know how to determine that in my program.

Another problem is that the "touchesMoved" only occurs when the first finger moves. The other fingers also get a movement information but this function will only be called when the first finger moves.

And the third problem I have is that the indices of the touches changes when new fingers touche the screen.
i.e. when I go-through the NSSet of all "[event allTouches]" the first touch can sometimes change to the second one when a new finger touches the screen.

This is my current code part:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [super touchesBegan:touches withEvent:event];
    NSSet* touchSet = [event allTouches];
    
    int i = 0;
    for (id touch in touchSet)
    {
        CGPoint Point = [touch locationInView:self];
        
        iOS_SetTouchBegin(i++, Point.x, Point.y);
    }
}

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    [super touchesMoved:touches withEvent:event];
    NSSet* touchSet = [event allTouches];
    
    int i = 0;
    for (id touch in touchSet)
    {
        CGPoint Point = [touch locationInView:self];
        
        iOS_SetTouchMove(i++, Point.x, Point.y);
    }
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    [super touchesEnded:touches withEvent:event];
    NSSet* touchSet = [event allTouches];
    
    int i = 0;
    for (id touch in touchSet)
        iOS_SetTouchEnd(i++);
}

My C functions "iOS_SetTouchBegin", "iOS_SetTouchEnd" and "iOS_SetTouchMove" always get the Index of the individual touch event.
But this is never guaranteed the correct Index.

I hope you understood my problem and anyone can help me.

Greetings,
Lukas

I have exact same problem. Not found and answer, yet.

multipleTouchEnabled = YES;
also seems to make no difference.

You have to set multipleTouchEnabled to YES if you want the behaviour you are looking for.

You need to set it in all the views involved
