Drawing line Continous.
- by japs
Hi All,
How to draw line continuous in uiview?
I have used below code and it works fine but after drawing line straght when i draw another line then first one gets clear if i do not clear that then they join each other.
Please suggest some solution.
(void)drawRect:(CGRect)rect {
CGContextRef context = UIGraphicsGetCurrentContext();
//for( Line *eachLine in lineArray )
// [eachLine drawInContext:context];
CGContextSetLineWidth(context, 2.0);
CGContextSetStrokeColorWithColor(context, [UIColor redColor].CGColor);
CGContextSetFillColorWithColor(context, [UIColor redColor].CGColor);
if (firstTouch.x != 0.0 && firstTouch.y != 0.0) {
CGRect dotRect = CGRectMake(firstTouch.x - 3, firstTouch.y - 3.0, 5.0, 5.0);
CGContextAddEllipseInRect(context, dotRect);
CGContextDrawPath(context, kCGPathFillStroke);
**CGContextMoveToPoint(context, firstTouch.x, firstTouch.y);
for (NSString *onePointString in points) {
CGPoint nextPoint = CGPointFromString(onePointString);
CGContextAddLineToPoint(context, nextPoint.x, nextPoint.y);
}**
CGContextStrokePath(context);
}
else {
CGContextSetFillColorWithColor(context, self.backgroundColor.CGColor);
CGContextAddRect(context, self.bounds);
CGContextFillPath(context);
}
}
