Question

我使用以下代码突出显示所选标签标题。

  [[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor], NSForegroundColorAttributeName,nil] forState:UIControlStateNormal];

  [[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor redColor], NSForegroundColorAttributeName, nil] forState:UIControlStateSelected];

以上代码完美无缺。我可以修改上面的代码来增加标签标题的字体大小并使其居中吗？

Answer 1

本准则将为您提供帮助。

// set the text color for selected state
[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor blackColor], NSForegroundColorAttributeName,[UIFont fontWithName:YOUR_FONT_NAME size:YOUR_FONT_SIZE],NSFontAttributeName ,nil] forState:UIControlStateSelected];

// set the text color for unselected state
[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor blackColor], NSForegroundColorAttributeName,[UIFont fontWithName:YOUR_FONT_NAME size:YOUR_FONT_SIZE],NSFontAttributeName ,nil] forState:UIControlStateNormal];


//To make title center use below one 
[[self.tabBarController.tabBar.items objectAtIndex:0] setTitlePositionAdjustment:UIOffsetMake(0, 0)];
[[self.tabBarController.tabBar.items objectAtIndex:1] setTitlePositionAdjustment:UIOffsetMake(0, 0)];

//if you have more tabs increase the index

试试这个：

    try
    {
        var query = from o in ctx.ORM 
            select new 
            {
                id = o.id,
                claim_no = o.claim_no,
                emp_id = o.emp_id,
                dept_id = o.dept_id,
                location_id = o.location_id
            };
    }
    catch (DbEntityValidationException ex)
    {
        var errorMessages = ex.EntityValidationErrors.SelectMany(x => x.ValidationErrors).Select(x => x.ErrorMessage);
        var fullErrorMessage = string.Join("; ", errorMessages);
        var exceptionMessage = string.Concat(ex.Message, " The validation errors are: ", fullErrorMessage);
        throw new DbEntityValidationException(exceptionMessage, ex.EntityValidationErrors);
    }

使用UITabBarItem外观将选项卡标题居中
