Decorate iOS UI elements

This section describes the presentation style attributes that are supported for iOS devices.

Foreground colors

In order to define the foreground color for items used in the iOS navigation bar, toolbar, and some items in the forms (Buttons, SpinEdit, Radiogroups, and row checkmark and disclosure indicators in list views), the iosTintColor style attribute can be used at Window level:
<StyleList>
   <Style name="Window">
      <StyleAttribute name="iosTintColor" value="white" />
   </Style>
</StyleList>

Background colors

Background color of iOS specific elements can be defined with the following style attributes at the Window level:
  • iosTabBarTintColor
  • iosToolbarTintColor
  • iosNavigationBarTintColor
For example:
<StyleList>
   <Style name="Window">
      <StyleAttribute name="iosTintColor" value="white" />
      <StyleAttribute name="iosNavigationBarTintColor" value="blue" />
      <StyleAttribute name="iosToolBarTintColor" value="blue" />
   </Style>
 /StyleList>

iosTintColor inheritence

The iosTintColor style attribute can be used at Window level to defined the text color for Tabbar and Toolbar elements.

However, when defining the text color at Window level, it has an impact on the form elements such as Folder, Button, SpinEdit and RadioGroup too. For example, if you set iosTintColor to white at the window level, Folder, Button, SpinEdit and RadioGroup element will appear as if they were hidden.

To avoid this, set another text color at the Form element level, as shown in the next .4st style file: 
<StyleList>
   <Style name="Window">
      <StyleAttribute name="iosTintColor" value="white" />
      <StyleAttribute name="iosNavigationBarTintColor" value="blue" />
      <StyleAttribute name="iosToolBarTintColor" value="blue" />
   </Style>
   <Style name="Form">
      <StyleAttribute name="iosTintColor" value="blue" />
   </Style>
</StyleList>
Important: Note that in the above example, the iosToolBarTintColor and iosNavigationBarTintColor define respectively the background color for the iOS navigation bar and the iOS toolbar.
