How can I draw a dot on the screen on touchesEnded using UIBezierpath

ios, objective-c, uibezierpath

Solution

Your path doesn't include any line or curve segments to be stroked.

Try this instead:

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
    CGPoint p = [touches.anyObject locationInView:self];
    static CGFloat const kRadius = 3;
    CGRect rect = CGRectMake(p.x - kRadius, p.y - kRadius, 2 * kRadius, 2 * kRadius);
    pPath = [UIBezierPath bezierPathWithOvalInRect:rect];
    [self setNeedsDisplay];
}

- (void)drawRect:(CGRect)rect {
    [[UIColor blackColor] setFill];
    [pPath fill];
}

Problem

Can someone here please show me how to draw a single dot using UIBezierpath? I am able to draw a line using the UIBezierpath but if I remove my finger and put it back and then remove nothing get drawn on the screen. ``` - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint p = [touch locationInView:self]; [pPath moveToPoint:p]; [pPath stroke]; [self setNeedsDisplay]; } - (void)drawRect:(CGRect)rect { [pPath stroke]; } ```
