iphone – 画下划线/删除线文字(MULTILINE STRING)？

CGContextSetFillColorWithColor(c,[[UIColor blackColor] CGColor]);          //THE TEXT COLOR OF THE StriNG TO BE DRAWN.

            UIFont *fontName = [UIFont fontWithStyle:@"Arial-BoldMT" andFontSize:13];

            if(FontOverLayUnderLine || FontOverLayStrikeThrough){

                NSArray *StringsArray = [textString componentsSeparatedByCharactersInSet:[NSCharacterSet newlineCharacterSet]];
                CGContextSetstrokeColorWithColor(c,[appDel.textDisplayStyle.fillColor CGColor]);
                CGContextSetLineWidth(c,1.0);
                CGSize StringSize;
                NSString *StringToDraw;
                for (int i = 0 ; i < [StringsArray count]; i++) {

                    StringToDraw = [StringsArray objectATindex:i];

                    if(![[StringToDraw StringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]] isEqualToString:@""]){

                        StringSize = [StringToDraw sizeWithFont:fontName forWidth:rect.size.width lineBreakmode:UILineBreakmodeCharacterWrap];

                        float x = rect.origin.x + (rect.size.width-StringSize.width)/2 + 7;
                        float y = 4 + StringSize.height*i;

                        [StringToDraw drawAtPoint:CGPointMake(x,y) forWidth:stringSize.width withFont:fontName lineBreakmode:UILineBreakmodeCharacterWrap];

                        if(FontOverLayUnderLinE)
                            y += (1.05) * StringSize.height*i +1;
                        else
                            y += (StringSize.height/2)+1;

                        CGContextMoveToPoint(c,x,y);
                        CGContextAddLineToPoint(c,x+StringSize.width,y);
                        CGContextstrokePath(c);
                    }
                }

            }

希望这对所有人都有益.

谢谢,
