iOS4.2: TouchBegan does not draw more then one circle per sensed touch
- by Christian
Hi all,
quick question (which might be a no-brainer for most here) :)
My code below should draw a circle for every time touch that is recognised but although more than ones touches are sensed only one circle will drawn up at a time.
Can anyone see any obvious issues?
This method sits in the XYZViewControler.m class.
TouchPoint.m is the class that defines the circle.
Thanks a bundle for your help and redirects.

- (void) touchesBegan: (NSSet *) touches withEvent: (UIEvent *)event {
NSSet * allTouches = [event allTouches]; // get all events
for (UITouch * touch in touches) {
TouchPoint * touchPoint = [[TouchPoint alloc] initWithFrame:CGRectMake(0, 0, circleWidth, circleWidth)];
touchPoint.center = [touch locationInView:[self view]];
touchPoint.color = [UIColor redColor];
touchPoint.backgroundColor = [UIColor whiteColor];
[[self view] addSubview: touchPoint];
[touchPoint release];
CFDictionarySetValue(touchMap, touch , touchPoint);
}
[[self view] setNeedsDisplay];
}
