How to draw underline to a multiline label without using CoreText?

Question

I have been trying to underline a multiline label but I am not able to do that.

I have referred to this link but this doesn't seem to help me.

How can be done without using NSAttributedString and coreText?

Answer 1

You could use some of these open source projects from GitHub which are like UILabel's but support an attributed string:

TTTAttributedLabel or OHAttributedLabel

Answer 2

Following steps can be helpful.

1. Extend UILable OR UIView.
2. Implement - (void)drawRect:(CGRect)rect
3. In that method get context using `CGContextRef ctx = UIGraphicsGetCurrentContext();

4. Set text you want to set using this.

   CGContextSetRGBFillColor(context,1.0, 0.0, 0.0, 1.0);
   CGContextSetTextMatrix(context,CGAffineTransformMakeTranslation(0,pageSize.height));
   CGContextSetTextDrawingMode(context, kCGTextFill);
   CGContextSelectFont(context, "Helvetica", 30, kCGEncodingMacRoman);
   char *str=(char*)[@"TEXT" UTF8String];
   CGContextShowTextAtPoint(context,476/2-200,673/2+100,str,strlen(str));
   

5. Set Line using this code.

   CGContextSetLineWidth(ctx, 3);

6. Draw line using this code.

   CGContextBeginPath(ctx);
CGContextMoveToPoint(ctx, thisX, thisY);
CGContextAddLineToPoint(ctx, thatX,thatY);
CGContextStrokePath(ctx);


Hope above collected segments of code helps you....
