Question

Hi I am working on an application where i have to draw something. When I draw with marker stroke it makes some edges, how i can avoid these edges?

Code for marker stroke

- (void)drawRect:(CGRect)rect
{
//    KidsPhotoBookAppDelegate *appDelegate = (KidsPhotoBookAppDelegate*)[[UIApplication sharedApplication]delegate];
//    brushPattern = (UIColor*)appDelegate.kidsSelectedColor;

    DBManager *dbMgr = [DBManager sharedManager];
    [dbMgr.c setStroke];
    for (UIBezierPath *_path in pathArray) 
        [_path strokeWithBlendMode:kCGBlendModeNormal alpha:1.0];  
}

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    KidsPhotoBookAppDelegate *appDelegate = (KidsPhotoBookAppDelegate*)[[UIApplication sharedApplication]delegate];

    myPath=[[UIBezierPath alloc]init];
    myPath.lineWidth = appDelegate.kidsBrushSize;
    myPath.lineCapStyle = kCGLineCapRound;
    brushPattern=appDelegate.kidsSelectedColor;
    UITouch *mytouch=[[touches allObjects] objectAtIndex:0];
    [myPath moveToPoint:[mytouch locationInView:self]];
    [pathArray addObject:myPath];

    appDelegate.viewContainsDrawing = YES;
}

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    UITouch *mytouch=[[touches allObjects] objectAtIndex:0];
    [myPath addLineToPoint:[mytouch locationInView:self]];

    [self setNeedsDisplay];
}

I achieved this smoothness with the help of this code https://github.com/levinunnink/Smooth-Line-View
