UILabel size

忽略 linenumber ，得到最大的size

{
        UILabel* lb=(id)[_vTableHeader viewWithTag:TAG_HEADER_LB_REMARK];
        lb.backgroundColor=TEST_COLOR_RED;
        CGSize maximumLabelSize = CGSizeMake(lb.frame.size.width,1000);
        NSDictionary *attributesDictionary = [NSDictionary dictionaryWithObjectsAndKeys:lb.font,NSFontAttributeName,nil];
        NSMutableAttributedString *string = [[NSMutableAttributedString alloc] initWithString:lb.text attributes:attributesDictionary];
        CGRect newFrame = [string boundingRectWithSize:maximumLabelSize options:NSStringDrawingUsesLineFragmentOrigin context:nil];
        CHANGE_FRAME_HEIGTH(lb, newFrame.size.height);
        CHANGE_FRAME_Y(lb, CGRectGetMaxY([_vTableHeader viewWithTag:TAG_HEADER_V_LOCATION_FLOW].frame)+8)
    }

当linenumber>1时候，得到size

{
        UILabel* lb=(id)_lbSignature;
        CGSize maximumLabelSize = CGSizeMake(lb.frame.size.width,1000);
         CGSize newSize =[lb sizeThatFits:maximumLabelSize];
        CHANGE_FRAME_HEIGHT(lb, newSize.height)
    }

{
        UILabel* lb=(id)[_vTableHeader viewWithTag:TAG_HEADER_LB_NAME];
        CGSize maximumLabelSize = CGSizeMake(1000, lb.frame.size.height);
        NSDictionary *attributesDictionary = [NSDictionary dictionaryWithObjectsAndKeys:lb.font,NSFontAttributeName,nil];
        NSMutableAttributedString *string = [[NSMutableAttributedString alloc] initWithString:lb.text attributes:attributesDictionary];
        CGRect newFrame = [string boundingRectWithSize:maximumLabelSize options:NSStringDrawingUsesLineFragmentOrigin context:nil];
        CHANGE_FRAME_WIDTH(lb, newFrame.size.width);
    }

TTTAttributedLabel size

{
        TTTAttributedLabel* lb=(id)[_vTableHeader viewWithTag:TAG_HEADER_LB_REMARK];
        lb.backgroundColor=TEST_COLOR_RED;
        CGSize maximumLabelSize = CGSizeMake(lb.frame.size.width,1000);
        CGSize newSize= [lb sizeThatFits:maximumLabelSize];
        CHANGE_FRAME_HEIGTH(lb, newSize.height);
        CHANGE_FRAME_Y(lb, CGRectGetMaxY([_vTableHeader viewWithTag:TAG_HEADER_V_LOCATION_FLOW].frame)+8)
    }

  {
        UILabel* lb=(id)[_vTableHeader viewWithTag:TAG_HEADER_LB_BROWSE_COUNT];
        CGSize maximumLabelSize = CGSizeMake(1000, lb.frame.size.height);
        NSDictionary *attributesDictionary = [NSDictionary dictionaryWithObjectsAndKeys:lb.font,NSFontAttributeName,nil];
        NSMutableAttributedString *string = [[NSMutableAttributedString alloc] initWithString:lb.text attributes:attributesDictionary];
        CGRect newFrame = [string boundingRectWithSize:maximumLabelSize options:NSStringDrawingUsesLineFragmentOrigin context:nil];
        CHANGE_FRAME_WIDTH(lb, newFrame.size.width+2);//HERE: text is clip, why ??
        CHANGE_FRAME_X(lb,  CGRectGetMinX([_vTableHeader viewWithTag:TAG_HEADER_IV_COMMENT_ICON].frame) - lb.frame.size.width -8);
        CHANGE_FRAME_Y(lb, CGRectGetMinY([_vTableHeader viewWithTag:TAG_HEADER_LB_COMMENT_COUNT].frame))
    }
    {
        UIView* v=(id)[_vTableHeader viewWithTag:TAG_HEADER_IV_READ_ICON];
        CHANGE_FRAME_X(v, CGRectGetMinX([_vTableHeader viewWithTag:TAG_HEADER_LB_BROWSE_COUNT].frame) - v.frame.size.width-3)
        CHANGE_FRAME_Y(v, CGRectGetMinY([_vTableHeader viewWithTag:TAG_HEADER_LB_COMMENT_COUNT].frame))
    }
