iphone - How can i draw a dot on the screen on touchesEnded using UIBezierpath -

can here please show me how draw single dot using uibezierpath. able draw line using uibezierpath if remove finger , put , remove nothing drawn on screen. thanks

- (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]; 

}

your path doesn't include line or curve segments stroked.

try 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]; }
