What should i do i am using unity canvas button and images

Hi Burhanuddin, thanks for reaching out. Since you mentioned that your Unity canvas UI (buttons and images) isn’t showing on iOS while it’s fine on Android, here are a few things to check:

• Make sure your Canvas settings are correct. If you’re using Screen Space – Camera, ensure the camera is correctly assigned. If using Screen Space – Overlay, verify that nothing (like a wrong sorting order or overlay conflict) hides your UI.

• Consider the iOS safe area. Modern iOS devices (with notches or rounded corners) sometimes require adjustments in UI anchoring and scaling to appear properly. A quick test is temporarily disabling safe area adjustments to see if your UI appears.

• Check UI element material and shader compatibility. Sometimes a shader working on Android might have issues on iOS. Try using the “UI/Default” shader for both buttons and images to rule out a shader-related problem.

• Look out for any platform-specific code. It may be that there’s a conditional compile (#if UNITY_IOS) or similar that unintentionally hides the UI on iOS.

• Lastly, verify your Canvas Scalers and reference resolutions, so that on iOS the UI isn’t scaled outside of the visible area.

Checking these common settings solved similar issues for many developers with cross-platform UI in Unity. If these don’t resolve the problem, please share your Unity project info (using the “Copy Project Info Into Clipboard” option) or a minimal reproducible example. That will help pinpoint if it’s a setting, shader, or code issue.

Let me know how it goes, and feel free to provide more details so I can help further!

it is not visible

Burhanuddin, if your UI is not visible on iOS but works on Android, here are some troubleshooting steps you can follow:

  1. Check Canvas Render Mode: Ensure that the Canvas is set to either “Screen Space - Overlay” or “Screen Space - Camera” (and that the camera is correctly referenced). If it’s set to “World Space,” it might not display properly on iOS.

  2. Safe Area Considerations: With newer iOS devices, UI elements can get obscured by notches or rounded corners. Use the Safe Area settings to ensure your UI does not extend beyond the visible screen area.

  3. UI Scaling Issues: Double-check the Canvas Scaler component settings. Ensure the “UI Scale Mode” is set appropriately (e.g., “Scale With Screen Size”) and the reference resolution is correctly configured for both iOS and Android.

  4. Material and Shader Compatibility: Sometimes, specific shaders might not work on different platforms. Ensure that the materials used for your UI elements are compatible and consider using the default UI shaders to rule this out.

  5. Check Platform-Specific Code: Look for any specific code that may be affecting visibility based on the platform. Use conditional compilation (#if UNITY_IOS) to debug.

  6. Debugging: You can add logs to print out whether the UI components are active and enabled on the iOS build. This will help pinpoint if the objects are simply set inactive.

  7. Update Unity and Needle Engine: Ensure you are using the latest versions of Unity and Needle Engine, as fixes and improvements are often included in updates.

If you continue to experience issues after trying the above steps, please consider providing more details about your canvas setup or specific settings you’ve configured. This will aid in further troubleshooting!

Good luck, and let me know if you need more assistance!

You’ll have to provide more information on what you’re using so we can help you. Converting canvas elements to USDZ is partially supported.
