Action Definition

1. Log in to the Kuika platform.
2. Open the project you want to work on from the Apps screen.
3. Go to the UI Design module.

4. Select the button and add the Device > Is iOS action from the + ADD ACTION menu according to the desired trigger event (Initial Actions, OnClick, OnBlur, etc.).

Conditional Display or Behaviour Definition

The boolean value returned from the ‘Is iOS’ action in Kuika is saved as a Screen Input, for example, isIOSDevice, and this variable is used as a condition in the Visible property of elements in UI Design to control visibility on iOS devices.

• Display an element only on iOS
• Redirect to different content: If the user is on an iOS device, a different screen or message can be displayed.
  

On a reference form screen, you want to display an ‘iOS User Guide’ download button only for iOS users. Android users will not see this button.

Adding a Button Display Action on iOS Devices

1. Enter the UI Design module.
2. Drag a Button element from the Elements panel on the left side and drop it onto the screen.
3. In the Properties panel, enter ‘Download iOS Guide’ in the Label field of the button.
4. Click on an empty area and follow this path from the + ADD ACTION menu: Onclick → Device → Is iOS

Configure the Is iOS Action

• Action Type: Initial Actions > Device > Is iOS
• Where to use: In the UI Design module, select the button element whose visibility you want to set.
  
  • Open the Properties panel on the right.
  • Find the Visibility field.
  • Here, select the Sometimes Visible option.
  • In the Condition field that opens, enter the variable or expression that will determine visibility. For example: isIOSDevice
  • Save your changes.

• Dynamic Device Control: The Is iOS action can be used to display different content for different devices. For example:
  
  • Display different messages on Android devices.
  • Use special elements that only work on iOS.
• Platform-based navigation: Navigation actions can be customised according to the device's operating system.
• Conditional action chains: Is iOS can be used to trigger other actions. Example:

• Make a different API call on iOS
• Different button behaviour on Android

Technical Risks

• Incorrect Condition Usage: If the action result is not used correctly, content may be displayed to the wrong user.
• Platform-Specific Differences: iOS devices' browsers and behaviours may differ in some cases. They should not be released without testing.
• Hidden Action Definitions: If the result of an iOS action is defined without being used, it will have no effect.

Is iOS Action is critical for designing platform-aware user experiences in Kuika. You can deliver iOS-specific content, filter behaviours, and define customised flows based on different devices. With its web and mobile support, it provides a powerful control mechanism for your cross-platform applications.
