Hi all.
I want to draw some curve in my scroll view using CGPathRef. I tried to draw this path but i see only the part of my CGPathRef which located at 320x480 pixels. Is it way to do that.
Thank you in advance. Here is my code
path = CGPathCreateMutable();
CGContextBeginPath(ctx);
CGContextMoveToPoint(ctx, [[pathArray objectAtIndex:0]CGPointValue].x,[[pathArray objectAtIndex:0]CGPointValue].y );
for(int i = 1; i < [pathArray count]; ++i)
{
CGContextAddLineToPoint(ctx, [[pathArray objectAtIndex:i]CGPointValue].x, [[pathArray objectAtIndex:i]CGPointValue].y);
}
CGContextClosePath(ctx);
CGContextSetRGBFillColor(ctx, 0.5, 0.3, 0.2, 0.5);
CGContextFillPath(ctx);
And when I scroll my view the line does not change its location. My goal is to move this line during scrolling.
