Create Line in iOS Objective C

Solution:

In iOS you can create a Line using CGContextref.The below code is used for draw a line in a view in x1,y1, is 0,0 and x2,y2 is 20,20.

   CGContextRef ctx = UIGraphicsGetCurrentContext();

  CGRect rect = CGRectMake(0, 0,20,20);

   CGContextClearRect(ctx, rect);

  CGContextSetStrokeColorWithColor(ctx, color.CGColor);

   CGContextSetLineCap(ctx, kCGLineCapRound);

   CGContextSetLineWidth(ctx, 10);

   CGContextSetAlpha(ctx, 1);


   CGContextMoveToPoint(ctx, 0, 0);

   CGContextAddLineToPoint(ctx, 20, 20);

   CGContextStrokePath(ctx);

   CGContextDrawPath(ctx, kCGPathFillStroke);
