根据ui控件的字体计算占用的长度

    //1.根据icon计算name的长度

    CGFloat nameX = CGRectGetMaxX(_icon.frame) + kBorder;

    CGFloat nameY = iconY;

    //计算用户昵称的长度

    CGSize nameSize = [_weiBo.name sizeWithFont:_name.font];

    _name.frame = CGRectMake(nameX, nameY, nameSize.width, nameSize.height);

    //2.设置vip的frame

    CGFloat vipX = CGRectGetMaxX(_name.frame) + kBorder;

    CGFloat vipY = nameY;

    _vip.frame = CGRectMake(vipX, vipY, , );
