I wanted to give an update to this answer in case someone comes here looking for a way to do this as I did.
我想更新这个答案，以防有人来这里寻找像我一样的方法。
You can give the label a class with this option :item_wrapper_class => 'class_goes_here'
您可以使用此选项为标签指定一个类别 :item_wrapper_class => 'class_goes_here'
Here is a full example:
这是一个完整的例子：
= user.input :resident,
:collection => [["In the U.S", true],["Outside the U.S.", false]],
:label_method => :first,
:value_method => :last,
:as => :radio_buttons,
:label => "Where is your principle residence?",
:item_wrapper_class => 'inline'

If you want you can pass new_classto the label doing something like:
如果你愿意，你可以传递new_class给标签做类似的事情：
<%= f.collection_check_boxes attribute, collection, value_method, text_method do |b|
b.label(class: 'new_class') {b.check_box + b.text}
end %>

The easiest way to change the label class for a checkbox is to insert the following in /config/inititializers/simple_form.rbor /config/initializers/simple_form_bootstrap.rb:
更改复选框标签类的最简单方法是在/config/initializers/simple_form.rb或/config/initializers/simple_form_bootstrap.rb 中插入以下内容：
config.boolean_label_class = 'form-check-label'

This should be pretty straight forward like mentioned above one should add :label_html => { :class => "myclass" }in order achieve this, for instance:
这应该很简单，就像上面提到的那样:label_html => { :class => "myclass" }，为了实现这一点应该添加，例如：
= f.input :remember_me, as: :boolean, :input_html => { :class => 'kt-checkbox kt-mock-span' }, :label_html => { :class => "kt-login-checkbox-label" }
= f.input :remember_me, as: :boolean, :input_html => { :class => 'kt-checkbox kt-mock-span' }, :label_html => { :class => "kt-login-checkbox-label" }
will create and assign the attributes for the styles on the checkbox's label like this:
将为复选框标签上的样式创建和分配属性，如下所示：

To get the label class I had to get rid of the auto-generated label and write my own.
为了获得标签类，我必须摆脱自动生成的标签并编写自己的标签。
this is in rails 3 with simple form 2.1 so YMMV....
这是在带有简单形式 2.1 的 rails 3 中，所以 YMMV ....
before:
前：
<%= f.input :remember_me, :as => :boolean if devise_mapping.rememberable? %>
after:
后：
<%= f.label :remember_me, :class => 'remember-me' %>
<%= f.input :remember_me, :label => false, :as => :boolean if devise_mapping.rememberable? %>
