}

-(void)drawTextInRect:(CGRect)rect {
   
    CGSize shadowOffset = self.shadowOffset;
    UIColor *textColor = self.textColor;
   
    CGContextRef c = UIGraphicsGetCurrentContext();
    CGContextSetLineWidth(c, self.outlineDeep);
    CGContextSetLineJoin(c, kCGLineJoinRound);
   
    CGContextSetTextDrawingMode(c, kCGTextStroke);
